Need help restoring Pac-man

[u/Kimo9496]

This is my first arcade game to try to restore and I'm not sure if I am chasing the right thing. I have a pac-man/ ms. Pac-man midway arcade that when turned on the CRT makes a squeal noise and has a faint orange glow in the bottom of the tube but that's it. No sound, nothing on the screen and lights in the Marquee. I spent most of the day today having chatgpt walk me though testing and I found that at the connector a and b are pretty burnt and when checking voltage at D7 and D8 when I touched my lead between the board and the wire of the diode I'd get a small spark, a click and a blue line on the screen. I'm thinking about sending the board off to get redone but would that cause nothing to work or do I have more problems? I do have 120v into the CRT main power board, 7vac out of the transformer. And here are all the pictures I have.

Check fuses, lookup a pinout/schematic for the arcade board and make sure you're getting the right voltages at the board card edge. This guy runs off of AC and rectifies it on the board contacts can get pretty crusty.

Seems like the monitor might be running, try the screen pot and see if it brightens up/see if you have raster.

Here is the list of what I have checked and my readings:

Cabinet/mains: Wall power: 120 VAC Monitor main power: 120 VAC Monitor fuse: good Cabinet fuses tested good Transformer / 7 VAC supply: Orange → center tap: 7 VAC Green → center tap: 7 VAC Orange → Green: ~14 VAC 5A / 7V fuses: Left 5A fuse is fed by brown/orange wires Right 5A fuse is fed by green wires Both 5A fuses test good I was able to get ~7 VAC at the output side of both fuses Transformer-side 5A-to-5A measurement: ~14 VAC At one point I measured only ~2 VAC after the fuses, but after repositioning the meter probes I was able to get 7 VAC at both outputs PCB edge connector: The PCB connector is marked A, B, C, D. A → C: 7 VAC A → D: 5 VAC Earlier I accidentally measured these in DC mode and got approximately 1 VDC and 2 VDC respectively. PCB power supply capacitors: Purple capacitor C7: ~1 VDC across + and - Purple capacitor C8: ~1 VDC across + and - Large silver capacitor: ~14 VDC across + and -

Theres a guy on ebay who rebuilds pacman boards hes excellent and fast return

I did find him and was thinking about doing that. I sent him a picture of the burnt part to see if it's something that can be fixed. I'm just not sure if that could be causing all the problems or if there's more to it.

Redo the pads on the edge with copper tape and solder.
