Having a rom issue with a Konami Djmain board running beatmania the final. 2 roms show an error in the test screen. I replaced every rom on the board and got the same results. I also replaced every socket and got the same result. Voltage tests good at 5v to the board. Another strange issue, 0 Rom 0 through 3 are all close together on the PCB. While removing roms to determine the ones that are showing bad I noticed O rom 0 would test as "ok" if O rom 2 was not present, and O rom 1 would test "ok" if O rom 3 was not present.

first, continuity test for broken traces between ROMs. ROMs can also be internally broken in such a way that makes them work when one or the other is missing from the bank, i.e. ROMs A, B & C may all be testing bad, but only B needs to be replaced because it gives a bad connection between A & C. not sure if this helps but glhf
Im tired of attempting to fix this board. Do you know of anyone willing to repair this hardware?
