I picked up a Smash TV last week and finally got around to replacing the severed AC power cord tonight. When I plug it in with everything plugged in, the monitor(K7000) comes on and I can see neck glow, but the switcher doesn't power up. If I unplug the monitor AC power, the game boots up and plays blind. I also checked the 5.9V line(from the isolation transformer to the coin door lights) and it's outputting around 6.3V with no load when I had the monitor on.
Since I'm still a noob at repairs, what should I be looking at for where the problem is? I checked the AC voltage at the switcher and it's around 134V, and it's the same at the monitor. I'm guessing it's a problem at the isolation transformer, but beyond that, I have no idea what to look for or where to troubleshoot next.
