Question about Toshiba 42H83 42" Rear Projection HDTV-Ready Television

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.

Power went low all things went dim since then are tv's are all red picture and sound fine but all red

You need to first: Unplug TV and let it sit 20 minutes.

Screens broke

You can go to www.tritronics.com and use your model number to see if they are still available . They are somewhat easy to install by removing the speaker grille on the bottom thus exposing the screws hold the frame that secures your screens . Sometimes the screws are on the back side holding the screen . Send a picture of your tv if you think you might want to try it yourself . The screens can be expensive . Also try to call around to see if a repair shop might have some used ones that will work with your tv that are in good condition . Could save big bucks . Good luck

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
