Hi, I have a Yamaha RX-V596 home theater that has all of a sudden
started to hum, unit is about 8 years old. . You can hear it in all the
speakers, it is coming from the unit itself, anyone know what I can do?
Thanks, Adam

If the Yamaha were actually producing hum, this would indicate most likely a
power supply problem.
Normally the Yamaha's protection circuit would shut it down in this
scenario.
Does the problem with ONLY the speakers and no other devices hooked up?
If not, perhaps a ground loop. This is not uncommon.
If so, maybe a main power supply capacitor open circuit - I'm not sure if
that would trigger the protect circuit.
