Picture is distorted on my toshiba 42h83 audio is perfect. started with this problem slowly and was able to correct by switching between tv/video selections. Now picture is distorted all the time.


Distorted in what way WAVEY? there is a problem in the past with 11 very small capacitors that can cause this did it help when it warmed up? The trouble is these capactors can be replaced. but it take someone whe can do very difficult solder called surface mount. i do maybe 2 a month its very labor intensive i am not saying this is the prblem but this set does have that history

I f you push you button and actually you listen that it clicks or feel it and no phiscal damage. Button is correct.
The tv is now in a system of protection. A diagnosis is needed to repair the unit now.

Problems witha toshiba rear projection 2002 50h71 model


sounds like you might have the hypermodule capacitor problem. there is a cuircit board in this set that has 11 very very small capacitors that go bad this is charistic of wavey lines that go away after warming up. and eventally not going away. we repair about 2 of these a month at our shop. we would loved to just replace the board but this board is not availble we cant find it. so we very carefully resolder these caps. with magnifers and twezzers. so i dont recomend anybody attempt this except experience technician., you can easly damage this board and once damaged u cant find the board.
