How to fix Onkyo TX SR 303 when it says phones engaged but no phones are not plugged in


Hello, I suggest a reset of the receiver. Please see the procedure below. Thank you, Onkyo USA.

To reset the AV receiver to its factory defaults, turn it on and, while holding down the [VIDEO 1/VCR] button, press the [STANDBY/ON] button. "Clear" will appear on the display and the AV receiver will enter Standby mode.

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 TX NR515 .. when in standby mode .. light is not coming on .. everything works fine .. i must have pressed something by mistake but cant work it out what ... on the display panel in standby mode...


If Zones are turned on or, if a mobile device connected to the Front Input is charging (MHL), the HYBRID STANDBY indicator won't light. See the TX NR515 owner's manual at http://filedepot.onkyousa.com/Files/own_manuals/TX-NR515_English.pdf for more info.

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.

Black and white picture from blu ray player


Run the Blue Ray straight to the TV and see if the picture is still in black and white. If it is you know that your reciever is fine and the problem lies in the player or the TV. If the picture is normal then you probably have a bad HDMI IC that will need to be replaced.

I have an Onkyo AV Receiver HT-R500 and when I turn it on, it turns on and in less than one second it turns back to standby. What could be wrong?.


Try disconnecting all the speakers and see if it does the same thing. If it doesn't, connect speakers again one at a time to find out which one of them is doing it. Make sure the speakers rating match the output of the amp.

Have ajustments all screwed up


If you can’t resolve the issue yourself, try resetting
the AV receiver before contacting your Onkyo dealer.
To reset the AV receiver to its factory defaults,
turn it on and, while holding down the [VCR/DVR]
button, press the [ON/STANDBY] button. “Clear”
will appear on the display and the AV receiver will
enter Standby mode.
Note that resetting the AV receiver will delete your
radio presets and custom settings.

Onkyo HT-SR800 won't turn on


If you call Onkyo directly, 201-785-2600, there is a procedure to "reset" the system, something like holding the power button on and holding down another button for a few seconds. Can't remember which, so I can't be sure, but try giving them a call.
