Color distortion I have Toshiba 32AF43 for about 4 years now. Everything was fine with the TV until this evening. When I turned on the TV, there was no picture but sound was fine. After a few hours, I turned on the TV again and this time the picture was back but it seems that it's missing green color so that the picture color looks funny. Any idea, what's the problem and how to fix it?

You can have a seine board from the following link:
But before purchasing, make sure that it would fix to your model (Ask about it to your repairman). If it does, do the purchase. Once it is in hand, the fix would take less than 24 hours.
Cheers. Thank You.
Hi,Yes your problem sounds like the DMD board.This is how it works: http://electronics.howstuffworks.com/dlp1.htm Basically the light of the lamp goes through a tunnel that carries a color wheel(rotating disc with a gamma of colors that creates the colors on your tv)then the light of the lamp goes through the DMD board which is a chip composed of around 2 million pixels that creates the images and colors.When it starts to fail it will create black bars,pixelation,color distortion or white dots on screens. Here's a video that will help you find where the DMd chip is located : http://www.youtube.com/watch?v=0jr_9A5Xd2Q Have a blessed one!
Sounds like a bad tuner/decoder on the Qam analog side of things. You can bypass this with a Clear qam converter box or a analog to digital tuner box or simply having this repaired upwards of $200 bucks.
I had the same problem when I accidently hit the remote. If you are hooked up to cable make sure INPUT is on the correct setting -- AV, S-Video, YPbPr1, YPbPr2, VGA, HDMI1, HDMI2, ATV & DTV (see button on TV or remote). Hope this solves your problem.
You will need to trouble shoot the start up and shutdown circuits. Often this is a minor component failing causing the set to not power up or go into protective shutdown. Do you have the service manual for this TV?
