Hybrid standby mode on onkyo nr656 - Onkyo Audio Players & Recorders

The Auto Stand-by turns off the receiver if there is no audio or video signal for 20 minutes when set to On. Thus it shouldn't be blocking the receiver from coming on if it is set to Off. When the USB Power Out on Standby (power to a USB device when the receiver is off) or Network Standby (enable network power on requests from the Onkyo app) are enabled, then you get the hybrid standby mode if the Power Management Auto Stand-by is active (On). There is also an HDMI Standby mode for throughput of an HDMI signal.

What devices do you have connected to the receiver? Try turning on a video or audio source before you turn on the receiver. The other reasons for the unit not to turn on is the protection circuit being engaged. This can happen from overheating or a loose speaker wire touching another wire or the back of the receiver. Usually if the unit has the protection circuit engaged, the display will indicate Amp Diag Mode. After the diagnostic test, the display will indicate if there is a problem (SP wire). If there is nothing on the display after the diagnostic, the receiver should work properly when it receives an audio signal to send to the speakers. If the unit has been overheating, make sure that there is good ventilation around the receiver. Also clean any dust off the unit.

Crutchfield has the manual for the TX-RZ730 on the product page: https://www.crutchfield.com/S-lvaBRQ0O5ib/p_580RZ730/Onkyo-TX-RZ730.html . The current link to the manual is https://pdf.crutchfieldonline.com/ImageBank/v20200223150400/Manuals/580/580RZ730.PDF .

I hope this helps. If you heard an abnormal sound or smelled smoke, then the unit has internal damage. Similarly, if the problem continues, I'd suspect a wiring fault between the internal power supply and the main board of the receiver. The unit needs service or replacement.

Hold the "VCR/DVD" button while pressing the "On/Standby" button, and the receiver should enter "Standby." Turn it on again by pressing the "On/Standby" button. Bear in mind that this will clear all the presets and other settings - but it may be those settings that are causing the problems.

Try to use S/PDIF (Coax or opt)for audio input instead of HDMI may solve the problem.

Confirm that your remote is dead. If so, then get a new one.

Check out google - you can use an am radio or a digital camera to check for remote operation.

Hello, I am sorry about your issue. The receiver may have detected a problem with a speaker or speaker wire. Please contact Onkyo at 800-229-1687 option #3 so that we can troubleshoot with you. Thank you, Onkyo USA

Hello, since the center speaker works now after it was replaced I would suspect the speaker. Thank you, Onkyo USA

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.

Did you check the remote with another Onkyo system at the dealer ??. If its OK try resetting the system. Remember you will loose all your stored presets ( FM and customized settings ) and the Amp will go back to factory settings.
While in standby mode hold down the DVD button and press the Standby/On button., the display will show Clear and the Receiver will go into standby mode. Turn it on and try the remote once again.

Had an Onkyo DV-SP301 that would only intermittently come out of standby. Found faulty resistor R2 on the power supply board (board ORTP-865), it was nominally 5600 ohms, measured much higher. This after checking most p/s caps! R2 runs warm when unit is in standby, so you may want to replace with a higher power rated resistor. I used same rating but 10 k ohm instead, worked fine then.
