Another project that's been lying around for a few weeks. New flyback and cap kit, looked great and worked fine for a few days, then suddenly the picture was nothing but scrambled horizontal lines, like the H hold pot was cranked totally out of whack. Turning the H hold pot on the main board from one limit to the other does nothing but narrow and expand the screen a tiny bit. Remote board was never disconnected, does the same thing in different cabinets, it's not a sync wiring problem, solder joints look like new, voltage on the big resistor is 125 on the low end. Any ideas? Thanks.
