wg7xxx med res monitor - hv shutdown trim dripping/melted?
I'm trying to troubleshoot this Wells-Gardner medium rez monitor in my APB. The screen is blank when I fire up the game. No static sound, no neck glow. Fuse tests ok. There is a noise almost like a cassette player eating a tape and light flickers that appear to be originating from under the chassis board, under the flyback.
I pulled the monitor to do an initial visual inspection of the chassis and noticed this syrupy shit I mean stuff that looks like it's coming from what the label calls the "hv shutdown". The stuff has dripped across a few resistors.
2 questions-
1. What does the hv shutdown do and what is this syrupy goo dripping out of it?
2. Do I measure the B+ voltage from the resistor on the left side of the chassis, outside of the metal frame near the flyback? Or is it measured from the one standing on its end on the right side?
Thanks,
Marc
