receiver shut by itself

[Greg R.]

I recently got an Onkyo home theater package (receiver is Onkyo R320).
It's worked and sounded great). Tonight, for the first time it just
shut off by itself. I turn it right back on with no problem and it's
staying up. I did not have the volume up real loud (just at normal TV
watching volume). It does not appear to be over heating, and I'm sure
the speakers are not shorting. Is this a freak incident or should I
have it checked while still under warranty? Thanks

Most modern day amp have built in protection circuits to shut down when the
have a condition that could cause damage. How long have you had your
receiver connected to the speakers you are using? Anything change in your
set-up recently?

I've oly had the whole setup for a month, the configuration it's in now
is the only only one it's ever been in (same speakers, same location,
etc). It's only shut off the one time.... One thing I do notice is, we
live in an old apartment and our whole place is fed by just a single
circuit breaker. When something liike the microwave or the fridge kick
on, the lights will dim. Could this slight "brown out" cause it? I
can't recall if this was happening when the receiver shut, but I'm sure
the condition isn't ideal...

I have seen receivers do this when a subwoofer is not attached to the
system, or if the unit is not programmed that one is present.

If all of you apartment is on 1 breaker, that would mean your fridge and
other devices are on the same circuit. It could be you had a voltage drop
out low enough to shut it down. I believe most power supplies are good for
down to 90V input.
Did your TV shut down as well?
Do you have a UPS for your computer system? They usually have software that
will track the incoming voltages over time. It may be good if you could
chart it.....

The subwoofer is attached (and receiver is configured for it). The TV
has never shut off before, but I have blown the 1 breaker a few times (I
think I'm at the limit my apt can take). All we have for compters are a
few laptops, so I don't really have a need for a UPS. This shutdown
only happened one time, I'm hopin it was due to either a fluke or "brown
out".
