If you have disconnected all connections from the receiver including your sources and the unit shuts down and goes in protect then there is an internal shortcircuit on the receiver and you would need to send that to an authorized service center. Now, since you just bought it 4 days ago, if you purchased it from an authorized dealer of Onkyo you could have it replaced since its way within the 30 day return policy. But, if you have purchased it from circuit city, unfortunately your option would only be the service center for repairs. If you send it to an authorized service center, you would need to put in a copy of your sales receipt together with a brief description of the issue you are encountering. Where did you purchase your 806?

if what Dark_Orbit said does not work try doing a master reset by ressing and holding the dvr/vcr button and stand by button simultaneously. This would erase all your assignments so you would need to reassign all your sources hooked up to your onkyo.

SOURCE: Onkyo TX-SR705 shuts down suddenly

Onkyo receivers have a safety circuit in them to protect the Amplifier from blowing up:

If you listen closely when it shuts down ( after a loud scene ) there is likely a loud 'Relay Click'..
If this is what is happening you might be able to verify it by turning the volume all the way 'off' and waiting for the circuit ro reset ( releasing the safety relays & returning power to the internal Amplifier ) : you should hear another click, yhen you can bring the volume back up carefully and there will be sound again.

This safety circuit trips when then Onkyo receiver detects an 'Over Current' condition on the
' Power Supply ' that feeds the internal 'Audio Amplifier'..

Generally caused by:

1.
Improper load presented to the Amp outputs ( FL, LR, RL, RR, SUB, CENTER )
If you can ( one at a time ) turn off the SUB, Center, Fronts and Rears: trying to re-create the failure each time while you have one part of your system disabled or having their level turned way down..
You can isolate where the problem is coming from.

- any or all of these speakers being the wrong Impedence ( I.E. 4 Ohms instead of 8 Ohms )
Unless the receiver manual or the sticker near the 'speaker connetor' specifies a range or another value, you should assume 8 Ohms. Your speakers should say on the back of them.

- any of the speakers being connected in parallel ( 2 speakers to a single one speaker output ) .. Two 8 Ohm speakers connected in parallel make a 4 Ohm load to the amplifier.

- If the Suwoofer is Passive ( Not having its own power cord and amplifer ) it has a
Passive Crossover : this crossover can have its own power rating or limitation.. If it is constructed with capacitors that have too low of a working voltage, then they can saturate and the crossover itself can present a load to the amplifier that will case this 'Over Current Shut-Down'..


You user manual should detail this.

Hello, the most used buttons can wear out over time. On/standby and volume are the ones that are used most often. I suggest purchasing a new remote. It is available at shoponkyo.com. Thank you, Onkyo USA

I have a Onkyo TX-SR806 HDMI output does not work anymore. Tried switching HDMI cables. My component video output works.


Sounds like you may have a bad HDMI card my friend. I had an issue with my HDMI card that was causing blue dots to appear on the dark parts of the screen, when outputting 1080p over HDMI. This is a rather common issue, so it wouldn't surprise me if your HDMI board needs replacement - especially if you've ever experienced the infamous blue dot issue.

Alot of loud feedback through speakers, a loud buzzing noise


What sources make it happen or which do not? All buzzing = something in the amplifier end. is it from all speakers or just one?
One external source= RCA cables not grounded. Reconnect them tightly with a twisting motion to wipe off oxidation.
