The Picture is filled with rainbow colors

    I have rainbow colors at top and bottom as well, and when i push the Digital Array button, to re-align, you can the little +'s at top and bottom are off. Yellow + is below blue +, but the +'s across the middle are lined up and white like I think they should be. Nevertheless, the Digital Array button does not do anything.

Hello Big Sav,

It sounds like you have a Convergence Correction IC problem. This problem happens quite often and is fixed by replacing the ICs and the biasing resistors. There are many articles on the Internet about how to do this yourself. Here is one:

I should mention that, If you do not have a background in electronics you could do damage to your TV by performing this procedure. I you feel that you can not perform this procedure properly have a qualified technician perform it or have the board serviced at a TV repair shop that specializes in board repair.

I hope this helps,
Thank you,
