Re: LG 50PA5500 in need of buffer board

It is the second one from the top on the upper buffer board.

Greetings,
My LG 50PA5500 plasma has the lower half of the screen working and everything works as well. This was accomplished by up plugging the UPPER buffer from then control board (S-suss??). Any way I have read that replacing just that buffer will cause damage and you need to replace the upper, lower, and control board, is this correct? What if I replace the IC that is causing the problem? I diagnosed that bad one by doing a continuity check between the ribbon connectors and the board interface. Only one showed a short. I work on an SMT and surface mount system so the tools are handy...
