Trying to manually fix color convergence on Toshiba 57H81

The convergence ICs and the six 1.8 ohm 1watt resistors need to be replaced. You can get the convergence repair kit for your model at www.tvrepairworld.com which has the Two Convergence ICs and the six resistors plus the CD with instructions on how to do the repair.

I'm having a problem with my Toshiba 57H81 Rear Projection TV where there is to much green in the picture. Adjusting the tint and colors only helps some. I notice when I turn the TV off rather than a ...

Two things---first if you don't mind give me a vote here--I am rated on how many problems I fix

Second---with the original remote go into the customer menu and select Convergence---see if you can adjust the other problem that way---I can if that helps you email you the instructions for going to the tech menu to adjust convergence all over the screen and and saving those adjustments----if you find the convergence will NOT adjust in some area of the screen you may have a convergence problem.

I would appreciate a vote here for my help and if you need the directions for the advanced convergence let me have your email.

Toshiba Rear Projection Tv 40WH08B

If the convergence on one or more color does not align using the convergence setup procedure, that means that one or more convergence ICs must be replaced, that is the reason why you get bad picture.

That means that the convergence ICs are bad and must be replaced, the job is about $200/$300.

Here there is an example of the repair needed: Fixing Convergence problems in RPTV's
