Anyone currently offering repair services on 4 slots?

Cab is fine; 1 slot works normally on it.

4 slot graphics, every slot, every game look like an acid trip.

Neo Geo boot screen, has the ‘Geo’ superimposed on the ‘Neo’.

Please and thanks!

6764A7C3-0BC4-49A9-8A78-3BA6F20BAD65.jpegNow I can’t even get it to boot into acid trip attract mode.

Goes to Unibios screen, no response to lever or button presses, no response w/ cab’s test and service buttons.


Locks up at Unibios screen.

What troubleshooting have you done so far? Have you cleaned your games and slots to rule that out? Cleared backup ram? Checked for battery leakage? Checked 5v rail? If none of that works, I'd use the DIAG BIOS to check for hardware errors. You got a chip burner?

I’ve done all that, and no DIAG and no chip burner.

Thanks for the ideas tho!

I’ll be sending it to BB.
