Questions about DC to AC Power Inverter

Q: Questions about DC to AC Power Inverter

I guess this can go in here since it is kind of hardware.

I am looking into buying a DC to AC power inverter to use in my car so I can watch DVD's on my laptop for long trips. I was wondering if anyone has ever used one of these, and how well they work.

I am planning on getting a 400 or 600 watt one. And I just want to run my ibook off of it.

Any personal experience and notes is appreciated, as I would like to get one soon.

A: Questions about DC to AC Power Inverter

Really need one that powerful for just a laptop - or are you going to run something else off of it. Now I'm not real sure on this but I've seen it with car amps, if you run something that powerful you could need a better alternator than a stock one? I had a friend once who when his camero would idle you could literally watch the voltage on the battery decrease, he had to actually drive to keep the battery charged with his speakers going.

Maybe Stormbringer will have a real answer.

Hi guys,

I'm working on a Toshiba Satellite A105 laptop. The laptop suddenly went dark while in use and now the screen stays dark. In a dark room, with a flash light on the screen, you can kind of make out a picture. I wanted to confirm that this is most likely a power inverter issue before ordering the part. If anyone could help i'd really apprecaite it, thanks!
**************SOLVED***********************:

Here is the solution for anyone interested: As I did some troubleshooting I found that the screen had a pinkish hue which an article mentioned that that usually means there is a problem with the BULB, not the INVERTER. What had me confused is that unplugging the cable from motherboard to inverter brought the bulb on for a second, but unplugging the BULB from the INVERTER did not bring the bulb on, so I thought 'maybe it is the power inverter.' I then took out the LCD monitor from an old dell laptop and hooked it up the the bad HP laptop with the HP'S POWER INVERTER to rule out whether it was the inverter or the bulb. Monitor came on just fine, which means the BULB WAS THE PROBLEM AFTER ALL, otherwise the bulb would flicker just like the bulb from the hp laptop did. Cheers!

I have a Gateway 450SX4 that just went belly up. I turned my back on it and then when I went back the screen was black. I could barely see the imaging on the black screen if I squinted and looked really hard. Is there any way to tell if this is a CCFL backlight problem or a power inverter problem?? Also is it possible to replace the CCFL on a Quanta Display model QD141X1LH06 ?? It seems to be integrated in the LCD with an aluminum sealed cover. E-mail responses also welcome.

Thanks, Trafcon

I have an HP DV9000 which had no picture on the LCD. Well, it had a picture, but it was very, very faint as if the back lights were dead. Works fine when plugged into VGA or if you squint/shine light to see the actual screen.

So I replaced the screen with my friends old screen from the identical model, assuming the backlights are part of the screen assembly. Apparently not, because it didn't take care of a thing.

So then I figured it must be the power inverter. Replaced that, too, and exact same problem.

What could possibly be wrong? I know how to replace the parts, I did it right. I can still faintly see. Is the backlight a separate part from the screen? Why else would I have no light at all? I know his screen and inverter work fine.
 

A:Screen and power inverter replaced, still nothing.

Is the laptop motherboard supplying the correct operating voltage and dimming control signals into the backlight inverter?

And yes, the backlight lamps are built-into the LCD panel itself. They have their own power cables and connectors for attaching to the inverter.

Working on a client's problematic laptop...it is a Dell Inspiron 5105.

Laptop was having problems with being unable to power on, and with a darkening LCD when it did power on.

Disconecting the touchpad fixed the power-on problem.

However, the LCD continues to malfunction. I can't tell if the problem is with the inverter, the CCFL, or the LCD itself. The symptoms are as follows:

Sometimes, the screen works fine.
Sometimes, the LCD comes on, but the backlight does not.
Sometimes, the LCD does not function at all.
Video out to a CRT monitor works fine.

There seems to be no way of predicting whether the LCD/backlight will work or not. Just, sometimes it does, and sometimes it doesn't. I've checked to be certain all the connections are secure...

Unhooking and rehooking the connections seems to make little difference. I've reseated the inverter and CCFL, which also seems to make no difference.

Any ideas as to which of the four--inverter, CCFL, LCD or (detachable, ATI) video card--is the problem? Or know how I could determine which it is?

As mentioned before, the computer would not boot reliably until the touchpad was disconnected. Is it likely these two problems are related somehow? I've been assured the laptop did NOT take a lightning strike, but i have only the client's word to go on for this.

Got so I can use notebook computer in car.

Are these safe to plug notebook computers into? Any assistance appreciated. Dorothy
 

A:ACDelco 100W Power Inverter

I've been using a ninety-five-watt version for about a year now with my Averatec loptop without detectable adverse effects. Mostly, I use it for charging; but, I have on rare occasions used it to run the system.

To be sure yours in sufficient to run the laptop you could monitor the state of the laptop battery's charge to see if it looses, gains or stays the same.

Example: If your laptop needs 130 watts and the inverter puts out 100 watts, your battery would slowly drain and the inverter would run hot and maybe fail after a while.

Frankly, I don't undertsand why so many people spend a hundred dollars or more for a twelve-volt power supply they can plug into a cigarette lighter when they can get one of these inverters for around 20 dollars or less. I got a package of two nintety-five-watt jobs for $20 at Sam's Club. That's only $10 each.

Hi,

I am looking for a backup solution for my desktop computer (read as: tight budget) which can notify through a software interface about time remaining till batteries run out.

I am trying to run a server on this machine which I'm planning to use to give a demo to some parties from remote location. So basically this desktop will be unattended. I have written a small utility to gracefully shut down the server in case of power failure so that it doesn't look as though it crashed . And this utility needs to read the time remaining till total shutdown from somewhere. So I am looking for a budget backup solution which can provide me this data. (It is doesn't need to log it or so, I'm just happy to scoop it from its process memory if I have to.)

Can you guys suggest any backup-solution or anything which can help me find the time remaining till this desktop shuts down, if running on backup power?

cheers

Hi guys,

I recently posted about trying to troubleshoot a power inverter vs a backlight. With some troubleshooting and help I was able to trace it to the backlight.

Now I've run into a slightly different problem. The screen is black (very dim and even looking at it in the light its hard to see the icons but you can very barely make them out). When I press the standy switch by the monitor it flashes on for a second with perfect colors (NOT purplish like in most ccfl bulb issues).

I took another ccfl bulb just to hook it up and the bulb did the same thing, flickers on and off. I hooked the laptop up to an external monitor and it works just fine (if i press standy I can see it going into standby on the external monitor).

I would say it is the power inverter at this point but would like a second opinion Thanks!

I'm about to go on vacation with my family and decided to bring my laptop along to keep myself entertained on the long car ride. My laptop only has a 4 hour battery and it's an 8 hour trip. So I bought a 12V to 120V power inverter so I could plug it into the cigarette lighter to power it. However, I noticed that the cigarette lighter port provides 120W of power and the inverter is 160W. My laptop only needs 90W to run (according to the manual). My question is: is it safe to use a 160W inverter when the power port only provides 120W? Would I just get the reduced wattage instead of the full 160W or will something fry when the inverter tries to pull 160W out of a 120W outlet?

Thanks to all in advance.

I have a Toshiba Laptop... A week ago, my screen has started going black and coming back. Just two days ago, my screen went black and did not come back. I thought my screen was dead but then I figured that the back light of my screen was gone because when I look at the screen carefully, I barely see the things on my desktop....When I turn on my laptop, I can see my screen for 3-4 seconds, then it goes black again. Same thing happens when I log on after log off... It again gives me the light about 3-4 seconds after just logging on, then it goes black again. I finally opened up the screen, and found the display inverter... and it again gives me the light 3-4 seconds after I plugged out and plugged in the inverter cable. I am not sure whether the problem is the inverter itself of the inverter cable. I really need help.
 

A:Distinguishing between display inverter and inverter cable problem.

It sounds like the inverter may be sensing an overload on its output(s) and shutting down after a few seconds. Some possible conditions causing it could be 1) the backlight lamp(s) failing, 2) arching of the inverter output cable to itself or the frame of the LCD panel, or 3) a failure of the inverter's overload sensing circuit that makes it think it is being overloaded, when it really isn't.

WARNING: Use extreme caution when working around a CCFL inverter with power applied to it. Portions of it will have hundreds of volts of electrical energy on it. You could receive a nasty (and possibly fatal) shock if you come in contact with the high voltage.

How much power does an dell inspiron 2020 all in one desktop if left on 24/7 with all the power savings settings disabled? I don't leave it on 24/7 but I am trying to get a cost of usage per hour in various modes.

I would also like to figure out how much less it would use if you put windows 7 in sleep mode or hibernation mode lets say an hour.

I am also trying to figure it how much it would save money at night if I just unplugged everything.

We are on Duke Energy Indiana, U.S.

Does a Screen Save use less or more power?

Thank you for this information in advance.

A:Power usage and Power savings settings questions

No clue. You`d have to compare 2 elecrical bills, but someone will come along with a technique.

You should never leave a pc on 24/7 if you`re not using it, that`s just crazy IMO.

You should have the monitor going off after 10 to 15 and sleep or hiber after 45 to an hour.

Of course a screensaver uses more power and just heats up the video card, no need to even run one.

Hello,
I am looking for some learned answers to some newbie basic computer power questions.
1. Is it true that no power strip will protect the computer from a direct lightning strike?
Having had a couple and lost a 17" Monitor to them, I am wondering.
2. Is it best to unplug computer from wall outlet to be completely sure.
3. How many of the members consider a UPS as necessary equipment and always use one?
4. Finally, will a UPS add any protection from lightning strikes? I believe it will help in small outages that we get.
Thanks for any opinions. Having just built this system I want to protect it.

1. Absolutely true.
2. Yes.
3 and 4. I consider a UPS essential with all of the power surges and brief outages we have in Florida. But do not rely on it to protect your computer from a direct lightning strike. It will not do it. When the lightning is heavy, unplug your UPS.

I just rebuilt my pc. I'm running a GIGABYTE GA-M57SLI-S4 AM2 NVIDIA nForce 570 with an AMD Athlon 64 X2 6400+ Windsor 3.2GHz. Two XFX PVT84JYDF3 GeForce 8600GT 512MB in SLI and CORSAIR XMS2 2GB (2 x 1GB) 240-Pin DDR2. I also have two HDD's, one a Samsung SATA drive and the other a WD IDE drive and one DVD RW-DL drive. I had a 400 watt power supply in there which seemed ample... apparently not. I was playing Crysis at near max resolution, everything on high, not VH when I started to smell something like melting rubber. Before I could kill the power there was a load pop and a blue flash then nothing. I don't think anything else went out with it. I plugged in an old ATX supply that was good for 300 watts, and I could get the mobo to start up. I didn't want to go any further since it just blew a 400 watt source. Anyways, my question is what wattage and brand should I go with? I know the one that popped was a cheapo, it came with the case when I bought it three years ago. Also how many 12v rails would you all recommend? and is there any real difference between the 24 pin and the 28 pin ATX sources? I know my mobo takes either, but is it better to use one rather than the other? Thanks in advance for the help.

Okay heres how the cookie crumbles: Its a regular old day on my laptop until I figure out that my laptop isnt charging despite the charger being plugged in. So I think rationall and try to figure out the problem before the computer goes kaput. I order a new charger off of Amazon etc. Etc. Then my battery reaches zero and something strange happens: the batterystatus when hovered over says 'plugged in not chargeing', thus I propmtly try to Google the issue but my laptop finally goes black and dies. Now I try and turn on my laptop with AC power (took out the battery, and pressed start) but it wont turn on.

hi DontStare,
 
When you said "the battery says its dead", do you mean the charge is stucked at 0% and says plugged-in not charging?
  - Link to picture
 
Regarding your questions:
1. There's no special method to boot the G505 using AC power. Just plugged-in the AC adapter and the unit should turn ON with or without the battery.
2. The plugged-in not charging issue is usually triggered when the Lenovo Energy Management / Lenovo Energy Manager is set to Optimized Batteyr Health (Win8) or Conservation Mode (Win8.1)
 - Link to picture

To check, try to charge the battery while the AC adapter is plugged-in and computer is off

If the battery still doesn't charge, I recommend you contact Lenovo and report the issue (they'll most likely give you a new battery).

Now that I've built my new system, my "standby" functions do not work as before. I'm pretty sure it is something i can set up, or does anyone know if the GA-7DX cannot do this?

When I press "standby" the drives do shut down, but the fans are all operating. How can I make the fans sleep as well?

Also, once my ssytem is in "sleep" the kbd or mouse will not wake it. Nothing wakes it. I have to press the power button and then it looks like it retarts! How do I make the keyboard & mouse come out of sleep?

Is that the same thing as Suspend To RAM? I dont have Suspend To RAM enabled - I'd have to set a jumper for that. I thought that sleep and suspend to RAM were different.

Any thoughts on these sleep issues?

A:power supply questions

Sounds like the bearings on the power supply fan are starting to seize. You can either replace the fan or the whole power supply. Lot's of sites sell both.
The cpu fan should be running. You had best replace that as well. Check and make sure it is plugged in and didn't come lose. should be a two wire plug coming from the cpu to the motherboard.

So long story short, my brother dropped my laptop a few times and it damaged the DC power jack to the point where it won't even charge even if I jiggle the AC adapter cable, bend it, or try and shove it in to the jack. I have a Gateway MD2419u laptop and when I talked to someone on the gateway support live chat, they said I'd have to get a new motherboard, but a local technician told me I just needed to have my power jack resoldered, or solder a new one on. So I'm just wondering, do I need a new motherboard, or a new DC power jack? I can easily just buy a new DC power jack and take the current one off and solder on the new one if that's the case.
 

A:Laptop DC power jack questions

"Easily"? If you can take it apart and put it back together, it can be replaced (or maybe just resoldered). But it is likely that the original soldering was done by a robot, so it may be a very small place to work in.

hi guys again

I was thinking if this is bad or not. Like for my pc setup, I have a bad habit of disconnecting my backup HDDs[3 of em] and reconnecting (ide+power wires)them just to transfer files, whats the point of having them connecting 12-24 hours a day if im not going to use them so thats why I have them disc., mainly for backup purposes.

Is it ok just to leave the IDE cable connected without the power wire connected(Really dont wanna disconnect ide cable out of my seagate one, afraid the pin might get ruined again)while my pc is running? I only use 2 main hdds on my bottom racket. Other 3 are just backups. Or to any IDE hardware with ide cable connected without power?.

Recently just fixed my seagate drive with pliers, I mentioned in another thread, where it was pushed in the pin, and when i pulled it out it clicked, now working full speed I suppose, now just need to test it out some more to be sure cause before with the pin pushed in it was like 1/4 of its speed only.

6 1/2 year old Dell Inspiron 546 Minitower running Windows 7 Pro.

The power supply died and I want to swap the dead power supply with one of the many old power supplies I have laying around. I realize a big part of installing a new power supply is that it will fit in the case. This really isn't important to me, even if it just hangs there by the cables, because all I want to do is boot it up long enough to do a back up of a few files to its DVD burner. I have already purchased a new computer but would like to get a few files off the old one. If it doesn't work that's fine but would like to give it a try.

Any electrical shock issues I can avoid? Maybe no grounding strap when I do this? Also, if the replacement power supply isn't the exact Watts or Volts will it probably still work. Like I say, performance here isn't important, just want it to boot, get a few files burned to a DVD and then it goes in the garbage.

I have all the stats on this computer and can also get the model and serial number off the old power supply if needed and was wondering what a new (cheapest) power supply would cost me?

Thanks
 

A:Power supply change out questions?

Rather than spend money, why not just pull the drive out of the old system and connect it to the new system? Windows will see the drive and assign the next available drive letter to the drive. Copy whatever you want.

Note if this is an ide type drive, then you are going to need an adapter, docking station, etc. If it is a sata type drive, then you do not need anything; simply connect it to the new system.

I wanted to ask if it would have less wear and tear on this hardware setup to put it in hibernation at night, keep it on 2 to 3 days straight and then turn it off one night, turn it off each night, or keep it on 2 to 3 days and then put it in sleep mode for one night unless reboot is needed with software?

I also wasted to ask about my monitor. Should I turn it off each night when not in use, or leave it on all the time and let it turn the backlight off after 20 minutes and when the PC is off?

I thank you in advance for any advice.

I feel (no documentation to back this up) That power up and down cycles causes more wear and tear on components. If the computer is not used most days hibernation is OK. I personally leave mine on 24/7 and let the monitor go into power save

My power supply on my CPU recently kicked the bucket and i have a few questions about it. I built my own PC but i got a case with a built in power supply and i was recently told that wasn't the brightest of ideas but that's besides the point. The current one i have is 500w and i guess basically here is what i wanna know.

A) Are all power supplies the same as far as size/compatibility with cases and such?

and

B) Other than wattage, what else should i look for?

Memory
I am building a computer with a Q6600 which will be overclocked. The motherboard is a Gigabyte GA-P35-DS3L (unless I have been out of the loop too long and there is a new inexpensive board that is widely recommended, please let me know). My options for memory are DDR2 800 CAS 5, DDR2 800 CAS 4, and DDR2 1000 CAS 5. How much performance gain would I see with CAS 4 over CAS 5, and how much would I see with 1000MHz over 800MHz? What effect does being able to run memory 1:1 with FSB? (The 1000MHz will probably run at 1066MHz.) Should I try to set the FSB as high as possible or is it just as well to run 800 x 4. I have read random posts and articles on this stuff in the past, but never really could grasp the concept. Could someone could clear things up in this area for me? Thanks.

Power Supply
The system will include the Q6600 and also an 8800GT. Everything else is basically standard, a hard drive, a dvd drive, a flash card reader... oh, and 4GB ram. I am going with a RAIDMAX SMILODON case that includes a 500W psu because it is a nice looking case, build quality seems decent, has good features, and includes plenty of fans. The rebate helps too. If I remember right, Newegg's pictures show 22A on the 12V+ line, (newegg's site has not been working right all day... is it just me?). Anyway, if I could get multiple opinions on whether this is enough PSU for the system... I know some people are all about expensive PSU's, and I have had one system with a core 2 duo ... Read more

A:2 Questions: Memory and Power Supply (purchasing new)

No real performance difference with CAS latencies at all and DDR2-1000 will give you a whopping 1% performance boost.

The only thing that DDR2-1000 is good for is overclocking your FSB.

This will give you a good idea of power consumption: http://www.anandtech.com/cpuchipsets/showdoc.aspx?i=3153&p=10

In looking at a new desktop either HP or Dell, I note that the power supplies that come with them are borderline adequate. I used to have lots of problems upgrading Dell power supplies. Physically, will these two manufacturers accomodate secong market power supplies (both physically and hookup wise)?

A:Power Supply/Graphic Card Questions

Don't get a modular PSU if you're not really, really, really persistent about having one or two cables less inside the case. It's just not worht the extra price, and the loss of power the cables cause, and the multi-rail design instead of the rock-solid single rail desing. Get this instead: http://www.newegg.com/Product/Product.aspx?Item=N82E16817139005 or this http://www.newegg.com/Product/Product.aspx?Item=N82E16817703005 even cheaper and well enough.
You'll need to post the model number of the HP, but I would say it fits. Also... I would still recommend a new case. HP cases do not have enough airflow for high-end components like (well, mid-high) 9800 GTX+.

Hey all,

I want to upgrade my power supply to a 550/600 Watt one, as I want to upgrade to a 640mb nVidia 8800 GTS and I don't think a 450 watt PSU would do it justice with a Core 2 Duo E6600, 2GB Corsair Extreme DDR800 Ram etc, 250gb Sata 2.0 etc..

Any help is appreciated,

A:Power Supply and Case Upgrade Questions

Measure the size of your current power supply, and look for which plugs and sockets your motherboard requires.
The better quality new power supplies come with everything you need.
Avoid "cheap" power supplies, but there are hundreds that will work fine... FSP, Antec, Color Master, CoolMax, Thermaltake, Apevia, Sparkle, PC Power and Cooling (the best, in my opinion), Raidmax, XCLIO, and most of the ones sold on the more popular websites are going to do the job. I avoid OCZ, and Corsair, Delta, Powerman.... You will find that most power supplies are made by just a few manufacturers in China and Korea. Save your receipt, as even big name, expensive power supplies can suddenly fail.

Here's the problem -
4 year old Gateway laptop, LCD went dark suddenly (could just make out screen in certain light.)
I figured out it was the inverter, order a new one, and installed it.
Hooray, everything worked fine. Bright clear screen.
I'll say here that the drive was wiped, so when it boots it boots to "No OS found."
Booted it up and left it alone for it to charge battery. Sat for 1/2 hour with no problem with "No OS found" bright and clear.
Re-booted to begin install of OS and it lit up, showed 'No OS found" for 60 seconds, and then goes completely black, not even faint.

So I can't tell now if this inverter went, backlight is shot, or ????
Since it starts every time bright and clear I have no idea. It just goes black 60 seconds after I turn it on.

Recently my Inspiron 8600 started booting with a black screen. Shining a flash light on it, I could see login prompt then XP desk top.

A:LCD inverter?

To be honest, the best way is by substitution of the inverter or the backlight. Whichever fixes it is the problem.

The high voltage produced by the inverter could be measured with an appropriate meter, but as it is effectively a ballast the results could be affected by the CCT backlight, it may be hard to deduce just which is the problem. Open circuit voltage would also be inconclusive, it could still be a defective inverter that falls over with the load and fails to strike the CCT.

I was given a slightly beat HP laptop when one of my customers upgraded. The video chipset still works (i.e. works fine when attaching an external display) but the screen itself is acting up. When the computer is powered up, the backlight turns on but there is just a single vertical line of colored pixels. I know all of the pixels work because if I tap the side of the screen they will display normally at any given time, but then the picture seems to get distorted or slowly burns out. So I'm thinking the inverter is junk, which is an easy enough fix... but I wanted to ask someone who has a bit more experience with this sort of thing. Any ideas?

I have a DCL LCD19A 19" LCD Monitor. It went dark and when I unplug then plug it in it lights up for a few seconds then goes dark again. I paid $139.00 for the monitor, and when I queried the manufacturer, they said they won't sell me the part, but for $99.00 plus shipping they will repair the monitor. Since this would probably end up costing me more than the original cost of the monitor, I am surely not going to ship it to them. I have opened the monitor (I am fairly technical and a Ham operator), and I cannot find a separate inverter. It appears that the monitor has a single board. Does anyone have an idea as to where I can find a replacement? Any and all thoughts would be much appreciated.

I've had my laptop for around 3 years now and just last week, the lower half of the screen flickered for a few seconds. I never thought much of it but over the last few days, the problem has become more noticeable. I have done some searching around and this isn't an uncommon problem, across all makers of laptops.

I have been advised to hook up an external monitor to see if it flickers in sync with the laptop, if it doesn't then it is most likely a failing LCD Inverter.

Does anyone know how much one of these would cost over here in the UK, or if they are all compatible?

Best regards

Hey,

The exact price is depending on your notebook model and display. Different notebooks have different hardware so there is no common inverter for all displays.

An exact answer you can get from an authorized service provider in your country. The guys have access to all Toshiba databases so they can tell you the part number and how much it would cost.

If you have a problem with a laptop screen is there a definitive way of telling whether it is the inverter that has failed or the screen? I have seen a number of forums mention the possibility of either but no way of actually definitively telling.

if inverter is bad, you can still see the image on the screen. if you don't see, so there's lack of LVDS signal from MB to LCD screen. in this case, you should check connection between MB and LCD, and if your laptop has nvidia geforce7200/7300/7400 videochips or nforce 6150go video, you should repair this laptop via warranty service.

I have a Compaq 6910p laptop running Windows 7. Lately I have been getting a pink tint to the screen and have tried all adjustment to the display settings I could find. I removed the bottom portion of the LCD screen by using the instructions on the Compaq web site. I disconnected the inverter checked for any cracks or physical damage and could not find any. I put it back together and everything seemed fine. It worked fine for about a day. I am now getting a pink tint again when I start it up but it seems to go away after a little while. I am now getting a flickering on the screen It was flickering at a pretty fast pace when I started writing this. It has now stopped the flickering and the tint is gone but I feel it is just a matter of time. Would this be caused by a bad inverter or is there a backlight in this that could be waiting to die? While I was having the problem I hooked it up to an external monitor and it was fine. Thanks

Hello everyone.

So I've been attempting to fix an older laptop with a busted CCFL or inverter. The screen is totally dark, no weird colors or anything. I figured this would be a burnt out bulb so I ordered a new CCFL. I got everything apart easily and soldered the new one in. When I put it back together however the problem is still the same.

I looked for websites on how to test the inverter with a multimeter but I'm still not sure what setting to use. This site http://www.asklaptopfreak.com/laptop-notebook-help/2006/07/12/test-fl-inverter-input-and-output/ says to use the 1000VAC setting but with the risk involved I have yet to try it.

Another thing I was wondering is if it was possible that I soldered the CCFL with the incorrect type of solder. I used rosin core w/ silver solder. I doubt that's it but I thought I'd ask anyways. Also maybe I got the CCFL in backwards? I didn't see polarity marks on the light but again, possible?

Any help at this point would be great. I'd mainly like to test the inverter though as I'm 90% sure that's the problem at this point. Thanks!

So my CCFL didn't light up so i order another inverter. well that inverter lights up my CCFL for like 2 seconds than turns off again. I take a part another laptop and use the inverter and the screen and could not get it to light up. However, i took apart a laptop with the symptoms of not powering on at all. I am confused.

HELP !
 

A:Diganosing inverter board

Are you using inverters matched to the computer motherboard and to the CCFL?

Different CCFL tubes need different voltages to operate and also draw different amounts of current. The inverter output needs to march the striking voltage of the tube and also be able to support the amount of current being drawn. The inverter typically has a current limiting circuit that may allow a lamp that draws excessive current to operate for a second or two and then cut out.

Different inverters also have different DC input voltage and current requirements and some require additional control line inputs to control the dimming function. They may not put anything out if the control line is left unconnected.

So my laptop (same one I've been trying to get a mouse to work on) had a blank screen, at all times. I can vaguely see the desktop or whatever is shown by using a flashlight, but I'm confused whether this requires a new backlight, or simply a new inverter.

I've already found the thread concerning opening up around the screen to view the FRU and PIN numbers for my current inverter (FRU: 27K9951 EC, PIN: 27K9952, on an IBM ThinkPad R51), but I'm unsure where to go form here. After a few Goole searches I've found a few decent prices (best being around $50) for an inverter, but I want to be sure I'm buying the right part to fix my problem. Just some confirmation or helpful tips would be helpful from the community, thanks a bunch.

P.S. I have already found the thread with the pictures of removing the frame, and from it I've understood that it is the inverter I need to replace, but better safe than sorry, I suppose - don't want to buy a $50+ part I don't need.
 

A:Inverter vs. New Backlight Bulb?

Inverter.
That is a very high price for an inverter for an R51, but the R51 is a very rare computer... so you may have to pay it.
you need a very good quality #1 hard steel philips screw driver, great care in removing and replacing the screw covers, and the time it takes to remove and replace 18 screws. But the inverter just plugs in. Mark all your screws as you remove them as they are not all the same length or diameter. But the most important function is removing the screw hole covers so you can use them again. You will benefit from a very, very thin flat blade screw driver or other tool to lift the screw covers out and off. You will need a nice adhesive that remains soft when you replace them.
It is very rare for an inverter to go out in that model.

I plugged the inverter into the cigarette lighter in the truck and then the Spectre charger into the inverter.  Unfortunately, it didn't charge and worse now it won't charge when plugged in to normal house 120 volt.  It says "plugged in, not charging".  When it is plugged in it is not using battery power, but it won't charge the battery.  Suggestions on what could be wrong and how I might fix it?  Thanks.

Had a customer call me with an IBM G40 laptop with issues.

Faintly see the graphics on the LCD screen and no back-lighting. I popped the trim on the LCD and checked voltage out of the inverter, nothing. I did notice that the LCD will light for just about 1 second when power is 1st applied to the inverter so that rules out a bad panel.

Has anyone ran across such symptoms on LCD inverters? I guess I can swap out a $26 inverter & see if it cures the problem.

Thanks

Would any significant problems be expected if I was to try to run my M93Z off of a modified sine wave inverter? I know that pure sine wave inverters are recommended, but it also sounds like a lot of desktop computers have components that monitor and smooth out the power input anyhow. I don't intend to use anything too heavy like video games, just a lot of Excel. Any thought woukd be greatly appreciated - thanks in advance!

The Intverter in my Audiovox FPE3206 has expired. Looking around I can't find the model inverter which is in the TV
(VIT70002.00). I can find a VIT70002.6. Can I replace one with the other?

A while back, user "raybay" posted some guidance on replacing the backlight and/or inverter on an ibm thinkpad r51 notebook. Here is a quote:

Inverter.
That is a very high price for an inverter for an R51, but the R51 is a very rare computer... so you may have to pay it.
you need a very good quality #1 hard steel philips screw driver, great care in removing and replacing the screw covers, and the time it takes to remove and replace 18 screws. But the inverter just plugs in. Mark all your screws as you remove them as they are not all the same length or diameter. But the most important function is removing the screw hole covers so you can use them again. You will benefit from a very, very thin flat blade screw driver or other tool to lift the screw covers out and off. You will need a nice adhesive that remains soft when you replace them.
It is very rare for an inverter to go out in that model.​
What I'm wondering is, this sounds like instructions for replacing just the inverter, but what if my problem is with my backlight as well (or instead)? Apparently they can also be replaced, but I've read suggestions that this may involve soldering. If you are lurking, raybay, do you know specifically what is required to replace the backlight on this model?
 

A:Replacing backlight/inverter on thinkpad r51

You can get the inverter, new, on eBay for $9.95 on up to $20... DO NOT BUY A USED ONE, and DO NOT BUY ONE FOR A SLIGHTLY DIFFERENT MODEL. It is the screen that determines the model number... and that inverter/backlight is part of that particular model number.
Your inverter and your backlight are basically the same thing the failure of one affects the other... or they are in the same device depending on the laptop.
None of the IBM Lenovo units need soldering... but you have to remove about 20 screws, and remove the rubberized screw covers... so making it pretty again when you are done is the hard part... as you have to learn how to reapply the screw covers and the rubberized stickum.
USE VERY GOOD, VERY TOUGH TOOLS. DO NOT USE TOOLS that wear easily. Cheap toosl will mar the screws and ruin stuff.
First you buy the backlight.
Second, remove the keyboard.
Third, you remove the screw covers with a very thin device like a 1/2 or #1 flat screw driver, only with thinner metal... and some tweezers to lift off and store the screw covers which are mostly very thin, round flat rubber disks.
You need some soft of bowl or series of cups where you can put the different size screws. You need to keep a chart of which size screws come from where... Unless you have a good mind for those sorts of things and nobody does.
You may find it easier to remove the back of the computer where the screen is kept... and CAREFULLY remove the ribbon cable for the screen that plugs in beneath the keybo... Read more

My Inspiron 1545 laptop screen no longer works properly. The display is extremely dim (just about impossible to see) so I figured I'd replace the backlight.

But I'm not sure what I should try to replace first - the backlight or the backlight inverter?

Anyone have a suggestion? I know the backlight inverter is much easier to replace, but is there any definitive way to tell which one is causing the problem?

Hi. I have a Sceptre S1902D-RV X9G-Gamer monitor. I am having the problem where, when powering the monitor on, it will turn on for a split second (and look fine) and then turn itself back off. Apparently this is because the inverter board is faulty, and replacing this board should fix the monitor.

I am having a hard time determining exactly which board is used in the X9G-Gamer, and also can't figure out where on earth I would go shopping for a replacement.

It seems like replacing one little board would be cheaper than trashing the whole monitor and buying a new one, and it'd also be kind of fun for me to crack this open and see if I can fix it ... but if it's going to be so much trouble to figure out, or just as expensive either way, I guess I should just get a new monitor.

Looking forward to your comments and suggestions.

My laptop is about 5 years old. When it boots, it works fine, but after a period of time, the backlight goes out. I can still see the screen if I look at it at an angle with a flashlight or something. If I restart the computer, the backlight comes back on. A week or two ago, the light would go out after a few hours of use. Now, it goes out within a few minutes of booting. Is this an inverter or backlight problem?

I recently sent in my old hp compaq to a service centre as the fan was making a noise, so I simply asked them to clean the dust out of the fan. I got a message from them 2 days later (!) to say that the screen inverter needed to be replaced. I replied to ask why, and they said it had stopped working and that it was nothing to do with the work they carried out as they only opened the back of the laptop to service the fan. My laptop went to them in perfect working order. Is it possible for the inverter to just stop working, seems too much of a coincidence to me. Does anyone know what causes the inverter to stop working? Thanks.

This unit's screen is barely visible (You can just about make out the windows logo on boot up). It works ok when connected to another monitor. The inverter has been replaced with the same fault? It has been to a repair shop who say it may be a micro switch of some sort??? I think it's just the screen.....Any ideas please? Many thanks in advance!

Hi,

Well from that description you do not appear to have much faith in the repair companies diagnosis!

So, why do you think they are wrong?
Do you have a spare screen to try?
Can you test the micro-switch function?

I have a Dell ATG-d620, that I use for field work. The screen has stopped displaying correctly, it is very dim. External monitor works fine. Self diagnostics tell me that the LCD Inverter Detection test failed. I wonder about trojans/virus etc because I have had a few on this machine, thought I got rid of them but... One symptom that I have not; when I hit ctrl+alt+del for the task manager, it does not display correctly, (no title bar, no tabs, little x in the corner to close it. etc) I am running Windows XP and a number of additional applications. anti virus: stopzilla, superantispyware 4.25, Winpatrol. Any help you all can give me would be greatly appreciated

I see a lot of inverters advertised on e-bay for a Dell Latitude D520. Problem is the D520 came with two sizes of screens, a 14.1" and a 15".

I wonder if the inverters for Latitude D520 work in all D520 regardless of whether the screen is 14.1" or 15"

My laptop LCD has been out for awhile and I've been using with an external monitor, but I decided to fix the LCD so I ordered a new LCD screen for it. The lcd screen arrives, install it and picture still doesn't show up. I then thought maybe I just had a bad cable from motherboard to LCD so I replaced that.. still no luck.

I can see a faint image in the background, but it's very dark. Same with my original screen.

What's odd is before my original laptop would show a just scrambled picture of black and white-- which is why I originally thought it was LCD.

What would the next step be? To order a inverter? Do the symptoms above sound like it's a bad inverter?

Hi,

I have a Toshiba Satellite Pro A120 laptop and I believe the inverter for the screen has gone kaput! It powers up, gets drive activity light etc but the screen is totally dead.

Anyone with experience know how easy it is to check / replace an inverter?

I tried to have a look at it at the weekend as I willing to try and I have been building desktops etc for years, just have little experience with laptops. Took it apart as best I could (which wasnt much) but couldn't seem to find my way into the case at all! Removed Battery, hard drive, RAM, modem and all the screws I could find and still I couldn't get into it.

Any thoughts / help / info greatly appreciated.
