Greetings! I'm new here, and new to arcade repairs, and could use some help. I know a bit about electronics, and I do alright with a desoldering pump, an iron, and a multimeter.
I have a "Pac-1 Pac-2" bootleg board, with Ms. Pacman ROMs installed, in what I think is an old TAITO / HOEI Space Bird or Space Battle cocktail cabinet, with a TOEI CM-B14N monitor.
The monitor blows the F3 (1A) fuse on power up with no other noise or signs of life (the game plays, but nothing from the monitor). The service manual:
https://usermanual.wiki/Document/TaitoTVMonitorServiceManualToeiCMR20andCMR14.647713656/viewsuggests that I should check for a short in B+, the horizontal output and HV circuits being likely culprits.
So far so good, though I'm not sure where to check B+ voltage, or where the high voltage or horizontal output circuits are (I can't find Q202! Q32 is top center, but no Q202).
Safety wise, I know general electronics safety precautions, about discharging caps, and the flyback at the tube (though I doubt any of that has gotten charged in a while), and running the monitor through the isolation transformer exclusively. Any other safety recommendations are most welcome, I've never worked on CRT tubes, or with high voltages.
When I first pulled out the monitor and did a visual inspection, I found a small cap that had obviously expired, and replaced it. I also replaced 2 larger ones (not the big filter cap though), because it looked like they had leaked, but in retrospect it was probably just glue residue. I also dusted the board because it was covered in nasty sticky black sooty dust, I only mention in case it's a meaningful symptom. I've also disconnected the video inputs to pull the monitor out.
Some pointers would be most appreciated.
Thanks!
