Question about Onkyo TX-8222 Receiver
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.

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.

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.

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.
