My panasonic projection screen tv is having problems with convergence on the sides of the screen.?

Question

I have tried to fix it manually with no results.

Answer 1

My first guess is power supply. But, that not a promise.
If you can find the Model Number and do a search, you may find better answers in some forums.
Type something like;
panasonic projection screen #2030-P (Whatever the model)
panasonic 2030-p convergence
You may have to try a few different ways of searching. But panasonic and model number be most important in the search and probably convergence.
