I have a CPS-1 with bad sound.
I say "bad sound" instead of "no sound", because it does play some sounds nice and clear.
It does not play any music.
The A PCB is the 89626A-4 12 mhz DASH model.
The B PCB is a Daimakaimura (Japanese Ghouls n Ghosts) reproduction. 91634B-2.
I did not create the roms.
In the test menu, it will play some of the sound effects, but none of the music.
No sound is made when inserting a credit.
When the opening scene plays out (after pressing start), only 2 sounds are played (no music), when the 2 characters are cut down by the demon.
When the game begins, 1 sound is made. That sound kind of echoes and then there is nothing but silence until the power is cycled.
I have created a video that demonstrates the issues I am describing: youtu.be/f1tHsWFhHc0
Does anyone know what may cause this issue?
My searches have revealed it could be the z80 but I do not want to just start replacing parts (although that may be required).
The game was working perfectly for about 35-40 minutes (level 5 for the 2nd time) and then a loud noise was emitted. After that, the sound cut out and it has been in the state described above.
I removed all the roms and cleaned all the sockets today. No change.
I originally posted this in the "Other Capcom..." section. Somehow, my brain was not willing to see the CPS1 section. I apologize for the bad first impression.
Thanks for your time.
