SOURCE: Onkyo TX-DS474 Receiver shuts down after Standby mode.

It's going into a protect mode. The amp is probably shorted out. Disconnect the spkrs and turn it on. If it still shuts off, it's the amp, if not, it's the spkrs.

SOURCE: Onkyo TX-NR905 Protection Circuit Activated

The problem is not with the inputs. This unit is in protect because a problem has been detected in the output section. Try disconnecting the speaker wires and turning it on. If the unit remains on, there is a short in one of the speaker wires. If the unit still shuts down, there is an internal problem that will require repair. It sounds like this is a new piece. If so, it should be covered under warranty.

Keep us posted,

SOURCE: Onkyo AV Receiver turning off - by its self.

The space you have provided should be enough. If this is a new unit and still under warranty, I would request warranty service. It sounds like the unit is entering protect mode. This may be due to heat or it could be because of a defect in the protect circuit. In any case, this should not happen that quickly.

Update this if not under warranty and I'll provide a list of diagnostic tests to help determine the problem.

Please provide instructions for how to play music from I phone/IPOD using analog. I plugged in the devise into the Video 4 area in lower right hand corner.

Hi Kathy, the easiest way to do this on your txsr700 would be for you to purchase Y connector which will have RCA connections on one end and a headphone jack on the other end. Connect the RCA cables to any open RCA connection other than the Phono input and then connect the headphone jack to the iPod. Please be sure that the volume is turned up a bit on the iPod. If you should require further assistance please feel free to contact our Product Support Team at 800-229-1687, Thanks, JT

Dont have my manual. i can't get am reception and it was good before. am reception is fine. also have a new lg led tv and the only audio coming out of the tv is an optic one, my onkyo tx-8511 does not have...

Register and download the manual for free at

As far as the TV audio goes... unless it is the primary source of the audio (tuned through its own antenna and available no where else) why don't you just run the actual primary source's (cable/sat, whatever) best digital audio straight to the Onkyo and skip the middleman that adds nothing to it but expensive unnecessary cable hops.

I'd also run each video sources absolute best video straight to the TV for the same reason.

How do I hook up my blue tooth headphones to my onkyo SR 605

You cannot rig up a blue tooth headphones to this receiver with out a blue tooth transmitter ( the Onkyo does not have one built in ). If you have a transmitter it can be plugged into the headphone out socket of the Onkyo ( in front ), just remember that it will cut out the sound from all your speakers when you insert the headphone jack . The advantage though with this connection is you can control the headphone volume using the Onkyo remote.

Hooking laptop to onkyo sr604 through hdmi no sound through stero

hdmi is video only

you will need to use the rca/phono inputs for audio.

you will need a stereo mini jack to steroe rca/phono

use the i/p marked aux/cd/

make sure the volume on the onkyo is turned DOWN before connecting any new input source.

The output from most laptops is designed for headphones so you may need to adjust the volume on the laptop DOWN as well.

Perhaps start off with laptop at 30% and the amp DOWN then increase the amp until you can hear the laptop sound.

To get good quality audio from a laptop you would be beter off with a USB sound card.

hope this helps, thanks for using FixYa

if this is helping please vote.

Onkyo receiver fried after hooking up to pc

I am not used to count colors or numbers on wires, but what you did is that you created an oscillator, by hooking up the output of the receiver and ran it through your computer which inverted the phase, so the thing oscillated and committed suicide. Onkyo used to make some good impact printers, before the modern inkjet came around. If your unit is within warranty, don't hesitate to go where you bought it and ask them to re-imburse you. Receivers don't blow up just like that, because someone hook a wire wrong. One of the specifications is to check just that: phase reversal and oscillations...
