Onkyo TX-805 7.1 fails to power up out of standby

My brand new Onkyo TX-R805 7.1 fails to power up out of standby mode. I have done everything the users guide recommends, evening letting it sit overnight, but the display never comes up. The unit clicks, waits, clicks, and returns to standby mode. Please advise. Larry

The unit has sensed an internal fault and shut down or the start up relay has failed in pin #3 inside the unit you will need a service tech to help, if its new the unit is under warranty, the other common cause can be a speaker short in the back, in the wiring or worse at one of the speakers, my new unit had the same problem twice, once for the relay and once because the unit error self test did not like the unit in 6.1 configuration with the left rear surround speaker, holding the power knob down on start up for 10seconds kicks in the auto self diagnostics mode good luck

Onkyo TX-SR 805 flashes message "Test - < - 42" when switched on at power button.


Hello, you seem to be in technician test mode. Unplug the receiver for an hour, turn on and perform a reset by holding vcr/dvr and then on/standby. This should resolve your issue. Thank you, Onkyo USA

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.

I have a onkyo tx-sr507 and it works great the only problem is the setup feature for the unit doesn't show up on my tv it only shows up on my receiver can anyone help me figure this out my cousin has...


A simple composite video connection from its Monitor Out to the appropriately-selected input on your TV may resolve that.

Or, from the manual...

"While the Pure Audio listening mode is selected, the video circuitry is turned off and only the HDMI OUT outputs video signals."

My reciver just shutdown then went into standby mode. Will not power back on. How do I fix this problem?


What do you mean by standby mode? Do you hear the power relay switch clicking constantly, or does it just click once and turn off? In any case, it could be a faulty power relay. I just sent in my TX-SR806 for warranty repair recently, and it ended up being just that.

No power


When an amp won't come out of standby mode when you try to turn it on at the receiver, there is usually a problem in the output section (shorted outputs) and the amp may also display something like "protect" on the display if it has one. There could be lots of other causes but outputs are the first thing I'd look at.

If its brand new, then return it for a refund.

Receiver keeps turning off after I turn it on.


CHECK THAT YOUR SPEAKER CABLES ARE NOT TOUCHING.ALSO DID YOU NOTICE THAT THE SPEAKER CONNECTIONS ON YOUR 605 ARE SIDE BUY SIDE NOT ABOVE EACH OTHER?

Brand new Onkyo Tx-sr605 won't leave stand by


If the unit will not leave standby I would remove all power, disconnect *all* connections at the back, reconnect to a power source and try powering on. This will eliminate any connection causing the Onkyo to stay in standby due to a short. If it still will not enter power-on mode, you may want to look at the power source (is it properly grounded?), but beyond that the unit probably needs to go back.
