Question about Sony STR-DB930 Receiver
It's most definately dry solder joints on the main PCB.
this is very common on this model and the DB-940.
these generate alot of heat when in use and is also the cause of the problem.
you may also hear the relays clicking from time to time and this means they'll need resoldering too.
hope this helps.

Re-engineering the speakers themselves is, well, don't do it. It isn't rocket science but it also isn
