Toshiba 42wh36p problem

I have a problem with my rear projection tv, when you first switch it on its fine then after about 20 minutes lines appear across the top of the screen which get worse until the picture breaks into red and blue and goes curved. I turn the tv off and on and it does it again after a few minutes. It gets worse the longer ther tv is on.

Toshiba 42WH36P rear projection TV has wavy lines

the problem is going to be a bad NEXT HYPER UNIT module. this is the digital scan card in the tv. try using the componenet inputs and if the tv works ok then you know that the HYPER UNIT is the problem. the reapir process for a "do-it-yourselfer" is too involved and would recommend a serivce center for this repair.

Toshiba model 57H81

If you have zagged lines there are 10 small surface mounted capacitors you will need to change on the HYper Board. This is not an easy repair so alot of folks simply replace the hyper board. You will need a service manual to take this set apart and to get the proper part number. If you have no TV repair experience or do not know how to solder, as the hyper board has sheild arounfd it, you should play it safe and call out a pro to assist you in this repair. Good Luck
