How can I connect my Onkyo TX-SR507 to a PC to play MP3 files

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."

Onkyo SR >> X << 507?? No such animal according to Google.

How about TX-SR507?

No USB.

Anything that has a headphone output can be adapted to feed an RCA cable pair for standard stereo to any audio device with a standard RCA input (except PHONO).

Get a cable like the one described here: http://www.monoprice.com/products/product.asp?
c_id=102&cp_id=10218&cs_id=1021804&p_id=665&seq=1&format=2

and connect it into any available analog input EXCEPT "Phono".

Did resolve the issue? I 'm pkanning to buy wii @ my home. Please suggest me.

I do use the Onkyo 507.

Check the laptop's audio controls. Try any input on the BACK of the Onkyo to make sure it's not a failure to select the input you're using.

standby light flashing means that it has had a thermal meltdown given that the onkyo can not be that old i would contact onkyo support because our model should be under factory warranty

go to the cox cable web site for the programming info on their remote

It sounds like you don't fully understand the Onkyo's HDMI port assignment procedures.

But why burden an HDMI cable with audio only? Don't you have a coaxial digital or spdif optical output on the PC you could use? That would make things simpler for setup. Just jam it into one of the appropriate audio inputs on the Onkyo.

Take the adapter cable from the Wii that plugs into the back of the Wii and converts the output(audio/video) into RCA style pin plugs, you will have: RED=right channel audio, plug it into any of the red audio INPUT on your Onkyo, then you will have WHITE=left channel audio, plug it into the other white INPUT jack next to the red plug on the Onkyo, then you will have YELLOW= video(picture) that will go directly to the yellow video INPUT on the back or side INPUTS of your TV.
Then when you want to play the Wii, set the input mode on the Onkyo to the inputs that you connected the red and white plugs into, then change the input on your TV to which ever the input is labeled on your TV in which you plugged the yellow plug into, you now will have sound comming from your Onkyo and the Wii up on the TV screen ready to play. Good luck!

Hello Katieandjona,

My first & second
guesses would be monitor & head-set modes...
(possibly Zone 2 activated)

ELSE...

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 (see page 93).
