Question about Acer Televison & Video
I have a 32inch Acer LCD TV, AT301W. When I first turn, it works for a minute and then the screen either goes black, or green, or checkers, sometimes it freezes on a picture. No matter what I can't turn it off from remote or TV, I have to unplug wait 30 seconds and plug back in. Sometimes I need to do this up to 3 times before it starts to work fine.
The problem is most likely the the screws are loose on the inverter boards. The screws must be tighted as they provide the ground to the inverter bds. The inverter boards are undet the shields on both sides of the unit after pulling the back cover. One way to make sure that you are losing back lights and not video is when your picture goes black, shine a flash light on the screen at an angle and will see the video is still there. This mean the back lights are out. If you do not see the video it may be another problem

SOURCE: LCD TV picture is green
I unplugged my TV for 15 minutes and that fixed mine a few months ago, the problem returned today, I noticed that it was only happening on the HDMI 1 port, when using my Xbox (on HDMI 2) the problem didn't happen
if you only have 1 HDMI source, try switching to the other port

Actually its a panel fault. You will need new inverter board for the panel. (That is if you get the power and sound, but no picture)

Sorry, this has no easy fix. The good news is you do not need an LCD Panel. The bad news is the Video Processor has a problem.
This TV has x3 Boards. The one you should replace first is the one in the middle. If this doesn't fix it, try the one on the right. The Part #s are on the Boards if you wanna try ebay.
