first of all, check all the capacitors. Other than that, it needs a repair guy to have a poke about inside it with a screwdriver. Has anything happened to it lately that could have upset it a little bit? such as a powercut or had anything done to the plug? (e.g. change of fuse, and put in one that was a different rating) And is it plugged into a surge protection socket, or a plain old fashioned electrical socket?

My SA-AX710 overloads intermittently. The problem is a broken solder joint between a pin on one of the power transistor modules and the circuit board. To fix it, I removed the circuit board from the case and resolder the borken joint. Opening the case is easy. First remove the top of the case. Then remove the 3 screws in front. The front panel can then be pulled off. After that, remove all screws holding the connectors on the back. The circuit board can be detached from the case by removing the screws from the top of the board. Broken solder joint is probably one of the most common problems with modern electronics.

Checked fuses then sprayed contact cleaner on the fuses and the fuse holders. The speakers began to work correctly.
