Hello Techs,
Unit came in with vertical lines top of screen. Replaced usual suspects
around vertical deflection heatsink, C451, C453, C455, C458 and a
.1uf/50V cap (forgot its board location). Anyway now I get vertical
distortion at the top of the screen while viewing a channel. With just a
blue screen (like from a VCR menu) I can see the top 5" of the screen
pulsing up and down, I rechecked all caps and verified the charge-pump
circuit is working properly. What am I missing here? Another cap?
Thanks,
David Lessard
