I have one of these units and its got a fault but if I could get a circuit diagram of all the units, I would have a 90% chance of fixing it.
This means I could also sort out audio problems.
Can anyone help with diagrams please.

Try new Speaker wire if you can, making sure the wire end is thick and folded over a few times, push it in firmly into connection and check integrity of wire to speakers
