Our 13' Audiovox AVT-1498 looses it's picture after it is on for about 5-10 minutes. We get a gray strip through the middle of the screen, but the sound is fine. We are assuming something is overheating. It is $200-$300 to replace. We already bought 2 portable DVD players for our two young sons, but we can not connect the PS2 to those. We were also looking into satelite television, because we regularly have a 10 hour drive to Grandma's house. Was there a recall we do not know about? Can we just replace a less expensive part?
If you suspect overheating then try removing the back and clean out with a long, wooden handled artists brush. Make sure the children are not about and try it with the back off, but do not touch things inside. You may blow cold air if you see what is overheating. See how long it works OK for. If it works without going off (assuming it was very dusty inside), then replace the back. If it needed a fan to keep it working you may find out what needs replacing.
The greay line you said is colled a frame collapes this is most likely to be caused by a dry joint on the frame output or in the general aera around the frame chip if you dont have a clue what im talking about seek pro help

The vertical output IC or the vertical circuit is whats at fault. its all solid state and im sorry to tell ya that its not a user replaceable part. This set is probably not worth the repair it would take to get this set working again but please if you like ask a ;ocal repair shop what they thought about this problem.. Good Luck and please dont forget to rate this thread

That model has a history of bad solder connections in various circuits. I would not be surprised if that is the case with the color circuitry. You may get the color to come and go by slapping the sides of the TV or lifting one corner about 1/2 inch and dropping it. If it does, it is a bad connection and possibly fixable. If no change is noted, it could be a bad semiconductor or capacitor, etc., causing the symptoms. For that size set, it would probably be cheaper to replace with a different brand. Toshiba has a nice 14" model IMO.
