Question about Onkyo TX-SV727 Receiver
My onkyo ht-r510 would not turn on. The three fuses i see on the insider are not blown. I removed all cables from the back, and tried to turn it on again. It came on briefly and then turned off, never to turn on again. From all that I read, it seems the dreaded protect mode was activated. I live in RI and there are no service centers near by. Is there a way to determine what specifically is involved in the "circuitry" that Onkyo says is avtivated to protect the system? The system was given to me and I am not going to pay to have it fixed. I would rather dump it and purchase a different make system that has a better service center network, than Onkyo.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

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.

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).
