it was the IC on the CRT board, pin 5 shorted to ground, replaced, all is
well, thanks to Jim and Damon and who ever else, you guys and this site
are a life saver, wish I could do more myself, but by the time I get on
most problems are already resolved, thanks again. now for the 85 mile trip
to take it back, can you believe that, at a buck a mile, mileage alone
is 340 bucks, plus another couple hundred for me and the part !!
oh my aching back
