Shut off during loud play


Many receivers have a thermal "overload" switch that will shut down power to protect the rest of the unit if it senses an issue like excessive heat, or if the ohms or impedance gets too high. This is a safety mechanism and you should probably seek a qualified audio repair shop for further troubleshooting.

My Pioneer displays Overload


Overload is displayed when the amp draw is excessive, and can be caused by different faults.
when Overload is detected, the protection circuit will shut down the unit to prevent further damage.

The first thing to try is hard reset. Shut down the unit for about one hour to drain power completely.
This can fix minor problems that can cause overload, for example electrostatic charge accumulation on internal capacitors.

If that does not fix the problem, then you must find the fault.

Overload can be caused by shorted speakers, wrong impedance speakers, or by a contact on speakers wiring.
Check speakers connection and test different speakers with 6, or better 8 Ohms impedance.

Another test can be done by unplugging all speakers, and reconnecting and testing them one at a time, at a very low volume.

If the speakers are OK, then preamp, shorted input/output connectors, main power supply or faulty output transistors can draw too much amps causing overloading.

In that case it is recommendable contacting Pioneer at the number listed on the owners manual.

I have run my surround sound through my Pioneer vsx-d510 receiver for years without a problem. Today it suddenly started shutting down and flashing overload. There is nothing on top of it causing it to...


Just the same, FEEL for heat.


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 or marginally low impedance loading by the speakers; 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 and competent hands-on tech.

When i turn my system on it plays a little and says overloaded and shuts down itself.What is the problem


Sounds like heat build-up.

Generally speaking, an amp protects itself from heat, shorts and overloads. Check for loose speaker connections.

Pioneer VSX D710S, I hook everything up and turn the unit on, after about 5-10 seconds it flashes POWER OFF and shuts down.


I wouldn't hold my breath waiting for free detailed circuitry.


A precise make and model might yield more-specific answer.

Make sure the speaker wires are tight.

I believe that smell is the death of a semiconductor in the surround power amp. How loud did you have it? As for an inexpensive fix, there will be hours of diagnostic work, and the parts can be VERY hard to find and expensive.
There is also the issue of safety. You should likely take it in for repair. Receivers aren't as dangerous as televisions or microwaves but they often have the two live 110V wires exposed near the primary of their power transformer. If you don't know what that means I strongly recommend you don't fix it yourself. These can also be dangerous even when they're unplugged, due to high value, medium voltage capacitors

Power overload


That is a good thing, your receiver is going into "protect mode" that means the receiver is shutting down to keep from damaging delicate internal circuitry, it is sensing a speaker bottoming out or some other electrical "short" that could be damaging!
Also could be from over driveing the amp and then it starts to overheat thus going into "protect mode".
If your speakers are "clipping or distorting" turn it down, you are going to ruin your amp. Good luck !

No more than two 4 Ohms speakers can be connected to the unit, or you will get overload.

If the speakers are OK, then preamp, shorted input/output connectors, main power supply or faulty output transistors can draw too much amps causing overloading.

In that case it is recommendable contacting Pioneer at the number listed on the owners manual.
