32inch Acer LCD TV, screen goes funny, need to unplug

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.

Issue with Samsung LE32B450. After the TV has been on for about 5 minutes, when you change channel the screen goes blank and the sound goes off. However, the TV is still on as pressing the power but


Just do a hard reset to this set and check. Unplug the TV from AC mains wall socket, and re-plug it back after 10 minutes or so. This must make it a hard reset.

My Sansui 32 Inch LCD screen shuts off, after a minute. The power remains on - the screen just switches off.


This may not work but i had a similar problem. My 32inch sansui LCD TV would switch off after about 10-20 minutes. I had to unplug it to get it going again. So i decided to open it as the warranty was long gone anyway. Very easy to open the back. I checked to see if anything was "swollen" as some sights suggested, but found nothing burnt , blown or swollen. Then i thought about heat? So i left in on without putting the metal backing plate back. It worked! when i put the plate back.....20 minutes and it shut down. So i just left the metal backing plate off! And no its not dangerous as the sansui has a protective plastic backing, that covers the metal one, that is better ventilated and protects the bits and pieces. Its been a week now and its fine.

What would cause the sound on a lcd hdtv 32 inch flat screen tv to just stop?


What other device are you connecting to your tv and how are you connecting it?

If you connect via a single HDMI cable that may be causing your audio problem. Some Tv and STB have handshacking issues which can knock out audio and/or video. The only solution would be to replace the HDMI cable or switch to composite cables.

Good luck!
