CHECK C2C52 10 UFD @ 50 V OFF THE BASE OF Q2C51 ON THE SIGNAL PCB. 2. CHECK C2P05 100 UFD 16 V OFF PIN 3 OF IC2P01 AND IC2P01 PART # 270P466020 (9-VOLT REGULATOR). BOTH ARE ON THE SIGNAL PCB.

Bad Tcon board or the cable going from the board to the panel, try that first by cleaning both ends if that doesn't help you need a new board

do the proper isolation proceedure and try unhooking the Su from the SC board to see if you then get a normal picture all the way across the bottom half of the screen? I am assuming the Vertcal extends extends all the way from top to the bottom of the screen?

I think you should take it back, cause! defective laser pickup, or the video processor, and possibly the audio/video cable, "replace to be sure"

The screen is ok Your T-Con board quit. You can get a new one from here: TV Parts Universal TV Stands DLP Chips ShopJimmy
