I have a G07 monitor from my Ms. Pacman that has an intermittent issue. A prior owner did a cap kit and appears to have replaced the flyback.
Every once in awhile when I turn the game on, I get a black screen and the monitor goes into high voltage shutdown. I then toggle power a few times and eventually the CRT turns on and the game play is normal.
Yesterday the part went into HV shutdown and didn't respond to power toggling, so I decided to troubleshoot it. I followed the G07 flowchart and found the fuses OK and B+ at approximately 150V. I then un-soldered X701 and the B+ was still high. I turned the game off and on again and the B+ is now 120V and the CRT is operating normally.
This is the second time this exact same troubleshooting scenario has happened to me. I suspect that I could have a bad solder joint, but a quick look does not show anything. I will probably just reflow the joints and hope for the best.
Has anyone out there seen something similar?
Thanks!
