Jeff do you have a print of the video circuit? The set turns on but black
screen on all inputs. Turning up the screen shows full deflection. Video is
getting stopped somewhere. I changed 108 caps most of them on the signal
board. When I first went to this church I had no power. Then changing all
the caps I had no picture then all of a sudden it came on and after awhile
it started rolling. I had one once that the rolling was caused by the PIP
section so I went through the PIP section and found 2 caps that were high
ESR. took it back over and now the picture doesn't come on at all. I figure
I'm back to the same thing I had before the picture popped on. Took the
signal board out and found more bad caps. But I still have no picture so I'm
going to need the print. Thanks for listening.
