Forum Thread: Neo Geo 4 Slot PCB Repair
I bought this the other day, it would only boot to the "crosshatch of death" although all diagnostic functions worked. It just wouldn't see any cartridges.
I stripped the top board off and had a good look at the bottom board.
Just around the battery i could see green/blue dusty fragments, there was corrosion around CN10 under the battery.
I spent a couple of hours doing pin continuity checks and finally took a chance on where the three missing tracks were going. I could have saved myself some time by doing a search on the net, as after I finished my repair I found the info I needed.....Typical
There were 3 missing tracks that had been corroded through so I put jumpers across them, (Probably need thinner wire but this was all I had on a Sunday)
It may not look that pretty but this is the final result,
I still have a few glitches with the cartridges but I think thats down to a clean of the connectors as if I tap them I can get glitchy graphics but that clears with another tap.
Very, Very happy with my days work
