It is common problem in this unit. Toshibia has a service bulliteen to service shops about this unit. It involves replaceing 11 16microfared surface mounted capacitors on the cuircit board known as :HYPERMODULE. I am currently got one of these in front of me now at the shop and the repair is rather difficult .,, removeing the board take alot and then repair the board take some doing ... you must be an expert at soldering surface mount components, i would not recomend this for a non tech. but on the good side your set is repairable.

Alot of rear projection t.v.'s have a convergence option in the menu on the t.v. There you can set the try to set the colors back how their supposed to. Mine has a cross in the middle of the screen and you just have to try to get all 3 colors to line up. Unfortunately, the actual lens inside mine has to be aligned so it doesnt work. Just something to try though, hope it helps.

Convergence issues with Toshiba 42H83 - Red lines will not align


Absolutely! if the consumer control has failed to rectify the problem you need expert help. There are two control boards near the power supply 1 or both are involved and more than 90% of the time both of the boards have to be replace otherwise the problem will occur again in a short time.
It is not a DIY project for the unskilled as it has to be tuned correctly when it is installed.
Better to leave it to the professional

Very wavy picture- gets worse when show has fast-cuts


First thing Do not beleive peeps about a bad card. Modules are not used in TV sets any more unles your talking about a complete board change out for a Zenith TV set. Toshiba sets do not have a card or board changeout!.. These peeps are crooks! A Toshiba set is repaired to componet level. It sounds like you may have a convergence problem or a problem inj the power supply involving the filter or couping capacitors. Seek out a pro whos an authorized servicer for Toshiba.
