The plasma panal is made up of a bunch of IC's that process the picture information

Each IC's takes care of a certain area of the plasama display

these IC's are mounted on FILM ribbon cable and are not replaceable once they go bad

The Ic that processes the area of the pix youare ahaving issue with has failed

what causes it?

Excessive Heat over the years chiping away at he glue/solder that was used to mount the ic to the cable

it cant be repaired once this happens
