NO sound out of speakers

I think the Amplifier Protection Circuitry was activated on my Onkyo Receiver TX-822. This is an older model. How to I deactivate or reset the receiver?

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,

u have a short.

remove all speakers cables and turn it on, if remains on and u can up the volume do the next.
1: turn it off.
2: connect only 1 speaker cable (each time to see if the short is in one speaker or cable)
3: turn it on, up the volume.
this way u must be able to see what cable or speaker have the problem.

if still the same prob the short is inside.
i put a answer of a prob where cant up of 41 check the cleaning method.

Good luck

SOURCE: Power will not stay on

Activated protection circuitry means that the amplifier is seeing conditions it does not like and is shutting down the power to prevent further damage.
Either you have a short in your speaker wires, in your speakers, or a blown amplifier.
Disconnect both speakers and turn on the amplifier. Does it still give the error message? If it does, your amp is blown. If it does not, carefully inspect your speaker wires and their connection. Make sure all looks good and reconnect the speakers and try it again. Still get the error message? You likely have a problem in your speaker cabinet(s).

Eliminate the short or overheating problem it thinks exists. Disconnect all speakers first to see if one of them is the culprit. If it's internal, take it to a shop.

I have an Onkyo TX-SR500. I turn it on, and immediately it shuts off. Under troubleshooting it says, "activated amplifier protection circuitry". Here is my issue: I've called Onkyo USA...


No one would be able to troubleshoot it over the phone or internet. Take it to a reputable shop and get an estimate, then decide if it's worth the cost.

This site said it was free - then there is a charge? I am getting a "Protecting" message when I turn on my receiver - then it shuts off....What does this mean and what should I do?


It means the receiver senses excessive heat, or a short at its outputs. Disconnect the speaker wires and see if that helps. If not, get it to a Tech. If it turns on, figure out which speaker path(s) was causing the problem and resolve it.

The manual.

Power shuts off immediately after power on.

• Amplifier protection circuitry is activated. Remove the power cord from the outlet immediately. Contact your Onkyo service center.

Can i connect 2 sub woofers to my onkyo receiver model tx-sr604 ,and if so how. and is bi wiring of front 2 speakears and surround 2 speakears any good iam using polk audios tsi300 as both front and...


You can hook as many subs as you like since the Onkyo only provides the Pre-Out Line Level to the amp(s) that drive it (them). I run two myself.

Bi-wiring is a personal choice and some swear by it while some of us swear at it in a modern home environment. The premise of bi-wiring is that your amps or crossover networks **** to start with so you have to do all this work-around.

My $.02 is you add complexity, waste speaker wire (which can be expensive if you subscribe to the theory that wire can change the sound other than at the cash register, but don't get me started on that), amplifier resources, and MAYBE you'll think you hear an improvement. Perhaps if you lived in an anechoic labratory you might. I think it's a crock.

http://www.brilliancehifi.co.uk/how-to-bi-wire-speakers.htm

If you look at the second diagram you'll notice the fundamental electrical circuitry of the speaker wire is essentially unchanged except you now have twice as much speaker wire. The same amplifier output posts still feed the same speaker input posts. How can this be electrically different?

You'll rarely find anyone who can produce a measured audible difference with any of the snake-oil schemes to get into your wallet. It's always flowery prose and faith.

No power


My receiver has a similar problem. So far I have found a pair of output transistors fried shorted E to B to C (Q6051 and Q6061) and the associated ceramic current limiting resistor array (R6101) failed open. These bad components will definitely be sensed by the protection circuitry as an overload condition. I ordered some replacement transistors from Mouser (2STC4467 and 2STA1694) and the resistor (RSS2WK-0.22 ) from Encompass.

I will let you know if this corrects the problem once the parts are installed. I also got a service manual from www.user-manuals.com which helps a lot.
