Color Problems My Toshiba 40H80 is showing a blue shadow on everything. It was fine the night before, the next day this blue shadow is on everything. I have tried using the convergence on my remote, but it will not fix it. Is there anything I can do?

Re: Color Problems

No they are soldered in the board, I am having same convergence problem also on a 51" Panasonic. I am trying to figure out how to get at the IC chips to replace them. Found a cool video on youtube..on convergence problems, and found parts on Ebay ..the STK392-110 ones....i hope this helped..thanks..John.

My 51" sony rear projector has blue shadow on image. pictures are fine but it has blue shadow. how can I fix that?

Clean the mirror or the blue color gun. You may have it next to a powerful magnet from a speaker system that can also distort the blue. If thats not it it may be bad convergence ICs

I have a toshiba 62mx195 with a bad light engine does anybody repair light engines?

Im having problems with my 62mx195.
The I have a good picture but i have shadows next to or on certain objects. It occurs over the whole screen at different scenes of show. There are blue shadows that pop up intermittently. I have tried hooking up different DVD players to the TV to see if there is a difference, but nothing. It seems minor but it annoying as hell. I hope it is not an Light Engine.

Convergence amp ICs need replacing and quite possibly the resisors that power the IC as they usually burn open when the iC goes out. You will need two ICs. Let me know if you need any more info.

Is it worth keeping???

I would suggest calling a repair shop explaining in detail what your problem with the set is and see if they can give you an accurate estimate on what the cost would be to repair your set.

No pic but sound :/

You are having a high voltage problem. Quite possibly in the horizontal deflection. I would check the horizontal output and regulator transistors.
