I'm am not certain, but it could be a safety circuit that is tripping the power. It will require investigation of the power supply to determine if it is good. It seems to me unlikely that it is the switch itself to blame. I think it would be rare for the locking mechanism of the switch to act like that.

The output transformers may-be gone
looking at +$50 AUS
for just the parts
or a licensed service

SOURCE: keeps turning itself off
If Both speakers are working at a low volume and you turn it up and it clips and shuts off you have one of 3 problems. you have over driven your speakers and one has shorted the voice coil but still will work at low volume, its a overload protection for ohms short in receiver. unhook each speaker and turn balance to the one hooked up and turn up receiver if it shuts off do the same with other speaker to determine which side is bad. 2 speaker wires are touching at speaker or receiver. 3 a bad receiver output transister. Good luck.
Unlike the budget stereo receivers now flooding the entry-level price points at dealers across the country, the Sherwood RX-4109 is designed and built in-house with the same quality and attention to detail we have been bringing to our audio gear for the last 50 years.
With 105 Watts RMS per channel, phono section, binding posts, a versatile remote control and switching for two pairs of loudspeakers, the only thing that bespeaks the word "budget" about the RX-4109 is its modest cost.
