I recently came across a Bank Panic sega convertacab and picked it up pretty cheap. The problem was no power. I put it in storage for a while, but now have some time to put into it.
I pulled the monitor, the monitor was shorting a 3amp fuse which was killing everything.
First thing I ran a complete cap kit. replaced the HOT and 2SC1106 voltage regulator. I replaced the power cable with new and a disconnect. I replaced the small pigtail fuse. (It looked funky - had some kind of condensation inside it)
The game is up and running, but playing blind. No HV, no static charge on the monitor, no neck glow. Metered the main power input wire at the chassis contacts. It's got 120 going in. I ran through the flowchart and pulled the x701 transistor, still nothing. I then ran through and reflowed alot of contacts. Still nothing. I checked the large ceramic resistor on the side, 161vdc on crt side(white wire), 168vdc on the other. I'm not seeing any cracked or cold solder joints.
I'm just guessing at this stage, could the flyback be bad? Shouldn't a bad flyback smoke or spark that was bad? I haven't run across many bad ones but I would think they would give some clear indication. Just not sure where to go next on this G07.
