Unhappy Mitsubishi 45" Problem

Hi
I have an old but formerly great operating 45" Mitsubishi Bigscreen (vs-459-rs). Turned it on yesterday and have a triple image, one each, Red, Yellow, Green worse at the corners, particularly left side. Convergence ?? Can I fix it myself?? How??
Thanks for considering my problem

You got it, convergence board problem. One or serveral voltage reg. transistors are shorted and possibly several low value resistors also. If you have never done this before you might need a service tech for this problem.

You might want to consider replacing the board, there should be a layout diagram in a pouch on the back cover, inside the cabinet or you will have to disassemble the lower front speaker area to get to the board for the part number.

Thanks for the reply. I thought that might be it. Will investigate further.
Thanks again

This a common failure on this set. The Convergence IC's have
failed.

Suggest you check http://www.treasurechestcorp.com/Default.htm

for a service manual. As Freddy said, there are usually a few
low value resistors that fail as part of the process. Look to the
convergence board for the failure. Also, check the fuses.
