Generally speaking, an amp protects itself from heat, shorts, overloads and operator exuberance 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.

My onkyo HT RC330 will not power up at all. Have had problems past couple of months with starting it but if you played around with swith it would start. Now nothing.


Try resetting the AV receiver To reset the AV receiver to its factory defaults, turn it on and, while holding down VCR/DVR, press 8 ON/STANDBY. "Clear" will appear on the display and the AV receiver will enter Standby mode.

It is possible that the protection circuitry has been activated. Remove the power cord from the wall.. Disconnect all speaker cables and input sources, and then leave the AV receiver with its power cord disconnected for 1 hour. After that, reconnect only the power cord and set the volume to maximum. If the AV receiver stays on, set then the volume to minimum, disconnect the power cord, and reconnect your speakers and input sources. If the AV receiver turns off when you set the volume to maximum, disconnect the power cord, and contact your dealer.

If the standby light is lit it and the unit will not boot it is most likely that the protection circuit has been activated. If there is no standby light then check the fuses. These units check that the power supplies are operating near specification. If a capacitor or resistor in the circuit, or a broken solder connection the unit will shut down. Because of the temperature the thermal cycling around the power supplies a broken solder joint can occur. This will make for an intermittent operation.

Hope this helps.

Onkyo ht-rc180 standby light blinks will not start.i tryed factory reset, still blinks


The amp protection circuit has been activated. Remove the power cord from the wall outlet immediately. Disconnect all speaker cables and input sources, and leave the AV receiver with its power cord disconnected for 1 hour. After that, reconnect the power cord and reconnect an input and a pair of speaker wires onto the unit. If the receiver still does not turn on than you will have to bring it in for service. Turn up the volume and if the receiver doesn't shut down, power off the receiver and add another pair of speakers. Power up the unit again and turn up the volume. If it doesn't shut down, power off the unit again. Now connect all your input sources and turn on your receiver. If the unit shuts down again, your unit will need to be further serviced at an authorized Onkyo service center.

Onkyo ht-r500 no speakers attached goes directly into protect mode, standby light blinking..


I have a HT-R520 - First thing stated in the manual is 'Do Not Apply Power to the System Until All the Speakers Are Connected to the Receiver.' This practice avoids any hot connects to the speakers. As with any high-outpiut system connecting spreaker wires to the system while in operation can spike the speakers as well as the amplifier curcuits. Hook up your speakers first and give it a try. Good Luck!
