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! http://www.tritronicsinc.com 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 problem is a back-light problem, it could be caused by a faulty inverter board or faulty CCFL lamp.

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.

Hi i turn on my pc and my monitor will come on and show windows and then it will go black.I tried it on another pc and it does the same thing can you tell me if i can fix this. thanks anns


OK :-) I am guessing that your monitor is corrupted and I think it's the monitor's problem not the pc's. I would recommend for you to borrow a friend's monitor and test it own on your pc to make sure if it's the pc's problem. If it works fine that means you should buy a new monitor.
