Hi Techs,
I am working on this chassis that has an intermittent vertical sweep
problem. It doesn't seem to respond to tapping on the board (like a solder
connection) but I have carefully resoldered the vertical section as well as
replaced the vertical IC and C423/C424. I am getting about 26v on pin 6 of
the IC (Vcc) but only about 1.4v on pin 3 (power for vertical deflection
output). Can some kind soul tell me what this pin should read and where the
source for this voltage is? Or better yet upload the schematic to Techassist
where I can download it. Any help would be greatly appreciated.
