Re: back light

I would suggest Tritronics for the service manual and the replacement parts. Unless you have a service manual, it takes a lot of disassembly by careful observation (or trial and error) to determine how that delicate LCD panel is put together! Of course I'd want to be sure that the problem is not in the inverter instead since that's a much more common cause of backlight trouble. Unless you happen to know it's one or more CCFLs, then of course you'd want to replace them all since they have the same aging.

It sounds like the screen is bad. A quick search with the model number and "LCD Screen" will show you that it would be cheaper to purchase a new monitor.

If it was the back light it would be an easier repair. But you are saying it does not come on at all so that is telling me the screen itself is bad.

Hope this helps! Please rate my answer :) Thanks!

Sounds like a problem with the video board of the monitor. I would contact Acer, since it less than 3 yrs old, tell them the problem that you are having get an RMA number and they will fix it for free. You only have to pay for shipping it back. Hope this helps.

The monitor gets dim as sson as it turns on. it

The problem is a back-light problem, it could be caused by a faulty inverter board or faulty CCFL lamp.

Monitor comes on and can see picture, but almost black screed have to look real close in order to see screen piture

Sounds like the back light on your monitor went out. All LCD monitors and TVs have a back light that is used to illuminate the pixels on the screen. This is how the "Brightness" setting on your monitor works. If this back light is burnt out, then it would be possible to faintly see the colors on the screen, but they would be nearly invisible as the light that was supposed to illuminate them is burnt out.

The solution to this problem would be to replace the back light on your monitor, but that is a very time consuming effort and you run the risk of it not working in the end anyway. I recommend purchasing a new monitor to save yourself some time and a major headache.

If you are still interested in repairing your monitor try going here for a guide on how you go about doing it. It may also be possible to find someone to repair it for you, but once again, it would be a lot easier to buy a different monitor in the long run.

You buy a new LCD Monitors, now still not working., if that new LCD Monitor is OK, then check your VGA Card, its inside the CPU maybe its broke or not connect properly inside. This are the cause of not displaying in your LCD Monitors.
If you here some beeps of your CPU then find out how many beeps and tell us here immediately.
