Question about Toshiba 43H70 43" Rear Projection Television
I took the right (Green) board out to repair bending convergent red signal and now it is flickering rapid. The board was tested OK and two STK392-110 ICs (driver chips) was replaced with 2 from electronix by a service repair person. It didn't flicker before replacing the 2 stk392s. What could possibily be wrong with It? Bad stk392s or something else? Maybe on the tan board? Please help.
The black box with 4 large red wires in it is the high voltage distribution box. One red wire brings the high voltage in and the other 3 bring high voltage to each of the 3 picture tubes. If those red wires are not all the way in and tight, then there will be high voltage arcing inside that box and the picture will rapidly flicker. Make sure all red wires are pushed all the way into those holes and your picture should be back to normal. Convergence IC's will not make the picture flicker, so I am sure your IC's are fine.
