Question about Sony DAV-SC8 System
I'm suddenly getting distortion from the Front Right (Red)Speaker and the both the two Surround speakers (Right silver/grey and Left blue).The remaining two speakers ie the Front Left (white)and the centre speaker appear to be fine. The distotion is very noticeable on piano pieces.
It sounds like the speakers themselves are the problem rather than the amp.
Although, it would be rare to have overdriven/blown the surrounds.
My suggestion would be to isolate which speakers or channels (on Amp) are at fault.
Swap left and right to see if the problem transfers across.

Generally speaking, an amp protects itself from heat, shorts and overloads by refusing to turn on or stay on.
Overloads can be from excessive periods of high output and shorts would be wiring issues or a speaker blowing up.
You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.
If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.
If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced hands-on tech.
