[TV] Re: RCA DLP 50"

Paul , solarization on pic is caused by misfiring of the plasma cells .
I had one Rca with that trouble once , and found a small potentiometer somewhere that helps clearing that problem , been a year so I don't remember the exact location , but it was on a very small board I think , around top middle.
