Trying to connect cable box....

"Onkyo TX-NR801 AV receiver using a coaxial digital cable but cannot get sound from the AV receiver." In onkyo amp, choose DVD, then in digital audio settings choose coax1. Then enter. In blu ray player, digital output selection choose auto or bitstream .

And you don't think the speakers are wired wrong. Re-investigate or reposition the speakers you THINK are Front to the Rear and go on from there.

it sounds to me like you have a broken dsp board. not a repair for amateurs

Need to be diagnosed my serv tech. This could be many thing. Most Onkyo receivers have 3 year warranty.

You don't.

Use whatever digital or analog audio outputs and S-video or composite video outputs that are provided on your source devices.

1-disconnect subwoofer first and test-and then disconnect surround speakers-and front speaker after-and later center speaker.ever time you disconnect you check the operation until you find the bad one(or two)which make the problem change its cable first and then change speaker itself.if all above failed contact the service center.

Turning any receiver off will erase the settings - there is no backup battery (Onkyo uses Battery Free Memory Backup) and the length of time depends on the capacitor charge. Why not just leave the receiver plugged in? Stand-by mode uses a negligible amount of power - enough to keep the capacitors charged and the LED on the front panel on.

you most likely fried a circuit board trace on the power supply

you are nuts, you must to use a computer with analog line input if you wanna record from analog sources to a digital media

I just read over the problem you were having with your Onkyo TX-SR500 receiver. It sound like the unit needs to be setup for all five channels.Sence your symptom says the diplay shows Dolby D3/2.1. According to the owners manual with the remote control look for speaker setup whin the button is pressed the current speaker setup will be shown in the display. Press the preset/adjustment<> to change the current setting to five speakers. the listening mode will automatically change according to the number of channels you selected. Hope this helps. Radiotech
