I've got a RCA surround sound receiver I've had for 5+ years (so old it doesn't have HDMI ports).  It hardly ever gets turned up past half way in volume.  It has recently started turning itself off randomly while I'm using it.

Is this a precursor to it dying for good?

It could be an overtemp condition that causes it to shut itself off to avoid internal damage.  Check the vents to make sure they aren't clogged with dust.  If they are, vaccum them clean.

In every unit I've ever had, turning the volume knob half way up is too much.  One third is usually about the max you can expect without the onset of clipping (distortion), etc.

Is it going to go for good?  Dunno.

You could have a short.  Check the speaker wire connections and make sure no bare (copper) wire is exposed.

Also, make sure it's not overloaded on the inside with dust.
Could effect the air cooling of the amp.

Or this, lots of ribbon wire in AV amps can have a cold soldering issue, might also check that out if you get inside of it.

Thanks for the input guys.  I hadn't thought of the overheating issue, but I did have some other theater components on top of it, so I unstacked them to see if that helps.  Checking for shorts will be next if the problem continues.
