Pioneer 1014 shutting down

[Youngin...]

I was watching a movie tonight and every time there was a loud action
scene the receiver would shut off. I checked the cables and replaced
them with a different set and switched from coax to optical from the dvd
player. It must have shut down 30 times. I let it sit for half hour
one time and then the next good action scene it went down again. I
figure it seems like a power problem but my wife says it did this to her
while listening to the radio one day and after it shut itself off three
times she just left it alone. That was about a month ago and it hasn't
done it since.

Check out your speakers do they match the power of the amp, and the
impedance, your receiver speaker impendance switch matches your
speakers , is power ratings of your speakers enough to handle the
power the amp , maybe that is why it's going off during loud sounds.

I am not sure but I think the ohm(impendance have to be the same for
all speakers.

You might get away with using 4 ohms for front and rear, my Yamaha
receiver calls for 8 ohm only on the center speakers,

Also I don't think you can use 8 ohms for front and four ohm for rear
in other words mix and match

Make sure the ends of the cable aren't touching the metal backing of the
receiver - it could be shorting out.

Also, how large are your speakers? Perhaps the speakers are overloading the
receiver?

Or... the receiver is defective?

Good point about speakers being large enough, but if it was shorted
speaker cable I don't think it wouldn't come back on until it was
corrected.

[Youngin...]

All speakers are 8 ohm.

I have large front speakers and small surrounds all terminated with
banana plugs. No wire is making contact with the back of the unit.

Had the same problem w/ my Yamaha.

It would work fine on normal volume - anytime I would crank it up or hit a
good explosion it would turn off.
Ended up tracking it down to the left rear speaker wire.
Replaced it and it was fine - after doing some testing on the wire - turns
out there was a short somewhere in the line - after closer inspection -
looks like a staple went thru the wire.

Try this - disconnect the speakers - execpt for the fronts and see what
happens.
If its fine - add the rears and see what happens.
Just a way to see if its the same problem.

Good luck.

Are the small speakers rated high enough to match the output of the
amp.
Of course it is very unlikley you would actually reach 100 watts or
whatever the power is, even twenty watts would have your neighbors
complainng.

Whenever somethings turning off its doing it for a reason, after two or
three tries you shouldnt try to "force" it anymore, unless you want to
damage something
Check your speaker wires, but I doubt thats it, sounds like a parts going
bad, and when they do they usually become heat sensitive and the receiver
shuts down with a high temp or power load.
If your speaker wires arent shorted then its probably something going
sideways. Now, you might think that you can play it at lower vollume levels
and it will be fine, but the level at which you can play it will get
lower... and lower... and lower
One more possibilitiy, your receiver is overtaxed by the load inposed by
your speakers, when you play it at moderate vollume levels its fine, but
tuirn it up and you get something called "clipping", which is hell on
speakers.
This used to provide a lot of business for speaker makers, nowadays a chip
tells the receiver to shut down in order to protect them when it detects
clipping. If you have a humongous set of he-man speakers that could be your
prob

Actually the poster said the rear speakers were small

[Archer]

I almost forgot, you do bring up good point about over heating. One
question does it have good ventilation, not "sandwiched" in between
other components. there should be nothing on top and free to breathe.

If not, l there is defintely something wrong, and needs repair.

[Youngin...]

I have an exhaust fan in my entertainment unit that keeps the receiver
very well ventilated but the amp wasn't doing this before.

I have watched probably 50 movies at least with the Pioneer at
roughly the same volume and this is the first problem that i've had and
we were watching a comedy to boot so the loud scenes were few and far
between.

You seem to be doing every right, but if you do have something on top
of your receiver, you might want to to take it off, if vents are
blocked, the fan is useless it becomes like a convection oven and gets
very hot.

I am not saying you do, but just in case you
you do. The rule is don't block any holes.

I am sorry I can't be a better help to you!

[Archer]

Of course it is quite possible the amp is bad

[Youngin...]

The only thing on top of the amp is the fan and thats right at the
back and only 2" deep. I think I found a short in one of the surround
speaker wires after some visual inspection.

I had a 5yr old Yamaha surround amp do that on high volume peaks ... I
think it cost less than $100 to fix, don't remember the components
that were replaced. Before getting it fixed I directed a desk fan
right into the top of the amp which helped until I could take it in
for repair. In my case, I was running 4ohm speakers and the amp was
really only rated for 8ohms - while playing loud music/videos the amp
would get very very hot, so I presume that led to premature component
breakdown.
