Convergence Problem Hello, my name is Josh and I have a Tosh Theatreview projection TV. The problem is with the convergence. Then I go to the secound convergence screen (push 1-9) the red will not come down in 3,7,and 8. On 7, it is pretty high and looks it is being shined from an angle.

There is a convergence board located inside the set that regulates the alignment procedure. this board is malfunctioning and there is a chip set on the board that has failed. you will need to replace this board in order to restore proper convergence functions.

Hello, I have a 60" Phillips rear projection TV


It sounds like a convergence problem; depending on your skills it may or may not be something you can do (parts cost on EBAY will be under twenty dollars).

I will attach some convergence photos: does your set look anything like these?

If it does and you can solder etc I can tell you the best place to get the parts and how to do it.

Before you rate this information let me know what you find.

Toshiba 43HX70 convergence problem


One or both of the STK convergence chips have probably failed.

I can give you guidance on this if you are confident to do the repair. I had the same problem with my Tosh 40WH08B and after replacing these chips it works like new.

This is a problem within the convergence circuit. If you can solder you should be able to repair this yourself. Let me know if you wish to attempt the repair and I'll provide additional details and instructions.

there is no convergence adjust in a 32" tv. Convergence is done when there is more than 1 picture tube, ie; 50" projection sets have 3 tubes so convergence can go out. post the model number of your set and we can help more, BMW Rider
