I have searched the internet for WPC-S DCS audio board schematics without any luck, anybody know if anything is available?

Mine plays audio for a few minutes after power up, then cabinet and back box speakers go dead, sound then restarts for a few seconds after each ball starts play, supply voltages check good, but that's about as far as I can get.

Cheers,

Chris.

Still no joy on schematics, but since started getting a 4 bleep code, U4 issue on DCS board, I pulled it to verify it and found corrosion in the socket, all a bit odd as the rest of the board looks great, so pulled all the EPROMS, they all had socket corrosion, so all cleaned up now and normal service resumed.

For reference the sound would die on both outputs after a short time, restored briefly when the next ball was launched.

Happppy :)
