UPDATE:
Replaced open R3340 that has the 200 volts through it on CRT ckt board,
still shuts down, also replaced IC on ckt board.
Checked picture tube, ok (has no shorts).
I also afterwards found that I can hold continuously any button on the
panel except the power and the set will come on and stay on with full raster
and normal hi-voltage but with snowy raster (no video) and no noise. Menu
functions will even come on screen.
I guess it's about time to let this old dog lie unless someone has any
good suggestions.
