Hey guys! Looking for some pointers
A few weeks ago I bought a non working 4 slot Neo Geo cabinet. Below are some pictures
Plugged it in and all lights and screen turns on but I've been getting some weird flickering and like solid color with boxes at the top. No coins are counted nothing happens when I push test switch no sound not much besides a flickering screen.
The board was pretty dirty and corroded I cleaned the board up could probly clean it up a bit more looks like someone at some point tried to fix some traces. I removed the battery to check for corrosion didnt see much.
I guess I'm just looking for maybe some pointer or if anyone has had this issue or knows where to start. This is my first project cabinet I'm pretty good with soldering bought some new equipment to test voltages and continuity.
I'm pretty active and will be checking back regularly.

Really appreciate any advice thanks!
