RCA Stereo turns off

I have a 6 year-old RCA stereo with surround speackers that turns
itself off after 2-3 seconds of playing music (radio, CD, or input).
If not sound is produced, it will not turn off. It seems to happen
when the music is at a normal volume too. If it is quiet, it will not
turn off.

Any suggestions? Is there a fuse or something that can be replaced?

Model number info might help, but it sounds like a protection circuit issue,
possibly detecting DC at the output (a distorted waveform might trigger the
DC detect also).

If it's not worth spending at least about 100.00 to fix it, then just buy a
new stereo. It's pretty unlikely you can repair it yourself.

What's the model number?

First, try it with no speakers connected, then with just one connected. If
it still works, try the same single speaker on the other channel. If it now
stops working, then the second channel tried is faulty - DC on the output at
a guess. If it doesn't work when you try the first channel, swap the speaker
to the other, and try again. If it does now work, then the first channel is
faulty. If it works on both channels with one speaker only, try the other
speaker on its own. If it now doesn't work, the second speaker or its wiring
is faulty. Likewise, if it doesn't work with the first speaker on its own on
either channel, but does with the second speaker, then the first speaker or
its wiring is faulty.

Can also be a filter cap in the protection circuit.
