Hi there

I have one voice down (common I know) - just silence.  It's not the ABCD cables, or the relays, have confirmed that.  Looking at the board for that voice, I can see someone has been there before me trying to fix it.  3 chips have a white dot on them (CEM3387, PCM53JP-1, M8724).  What do you think this might mean?  "I replaced those" "those are ok" ??

Any body else brought back a silent voice?  What was it?  (don't talk about the cables, I eliminated those...)

Swap the two sound boards (channel boards). Has the faulty channel "moved" ? (From channel 1 to channel 9 for example) ?
This is the first thing to do, the flat cables ABCD are most of the time not relevant in this case.
