SOURCE: onkyo HT-R500 amplifier protection circuitry activated

u have a short.

remove all speakers cables and turn it on, if remains on and u can up the volume do the next.
1: turn it off.
2: connect only 1 speaker cable (each time to see if the short is in one speaker or cable)
3: turn it on, up the volume.
this way u must be able to see what cable or speaker have the problem.

if still the same prob the short is inside.
i put a answer of a prob where cant up of 41 check the cleaning method.

Good luck

SOURCE: Power will not stay on

Activated protection circuitry means that the amplifier is seeing conditions it does not like and is shutting down the power to prevent further damage.
Either you have a short in your speaker wires, in your speakers, or a blown amplifier.
Disconnect both speakers and turn on the amplifier. Does it still give the error message? If it does, your amp is blown. If it does not, carefully inspect your speaker wires and their connection. Make sure all looks good and reconnect the speakers and try it again. Still get the error message? You likely have a problem in your speaker cabinet(s).

Eliminate the short or overheating problem it thinks exists. Disconnect all speakers first to see if one of them is the culprit. If it's internal, take it to a shop.

No one would be able to troubleshoot it over the phone or internet. Take it to a reputable shop and get an estimate, then decide if it's worth the cost.

I have an Onkyo TX-SR500. I turn it on, and immediately it shuts off. Under troubleshooting it says, "activated amplifier protection circuitry". Here is my issue: I've called Onkyo USA...

This site said it was free - then there is a charge? I am getting a "Protecting" message when I turn on my receiver - then it shuts off....What does this mean and what should I do?


It means the receiver senses excessive heat, or a short at its outputs. Disconnect the speaker wires and see if that helps. If not, get it to a Tech. If it turns on, figure out which speaker path(s) was causing the problem and resolve it.

The manual.

Power shuts off immediately after power on.

• Amplifier protection circuitry is activated. Remove the power cord from the outlet immediately. Contact your Onkyo service center.

Amp protection circuit has been activated


sometimes the protection circuit will enable because of a bad speaker i would suggest taking the load off of it by removing the speaker wires and turning it back on. if it stays on take an ohm meter and check the speakers should be between 2-4 ohms load.

No power


My receiver has a similar problem. So far I have found a pair of output transistors fried shorted E to B to C (Q6051 and Q6061) and the associated ceramic current limiting resistor array (R6101) failed open. These bad components will definitely be sensed by the protection circuitry as an overload condition. I ordered some replacement transistors from Mouser (2STC4467 and 2STA1694) and the resistor (RSS2WK-0.22 ) from Encompass.

I will let you know if this corrects the problem once the parts are installed. I also got a service manual from www.user-manuals.com which helps a lot.
