Hi all, i have an issue with a MVS MV1F, 1 slot.
Sounds, in this case FX, effects, voices, are distorted, i dont know how to explain it. Music works fine.
I have repaired many mvs boards but i cant find the problem in this one. Traces between ram (6116), SM1 , Neo-D0, z80, Y2610 are tested, following the jamma nation diagrams.
I have replaced the Y2610 and nothing changed. I have been 2 weeks with this board and I dont know how to continue, any idea?
Tested Neo Diag bios too, I can see Z80 expected C3, Actual: 00, but I am not using the M1 eprom so this error maybe I can skip it.
