I agree with the initial approach of the CRT board, but that is not it,
since only the bottom 50 lines or so are affected, losing sync, so it is
probably on one of the main boards. In 1982 I tried the TV repair
business and opened a shop just about the time TV's became throw aways,
bad timing.
I have also been nailed by the 25,000 volts on the big screen sets, and
after being kicked across the room once I got real careful. If it isn't
a solder problem it may just be a thermally sensitive chip, and if it is
too much work I will take it to the local church and buy a new LCD
monitor for less heat.
Thanks though,
