SOURCE: Onkyo tx-sr800 PROTECT mode

Hold video1 and press speakers A button, it will say "clear" If the message protect appears again, then its service time.

SOURCE: My Onkyo Receiver TX 601 is turning itself off

Adjust bass control to half position then feed loud signal,if it shut off adjust the bass contol to zero position,if it shut off again the defect is in the over load protection circuit it is already sensetive to loud signal.you may call the nearest audio amplifier technician on you.

Hope it may help you,

SOURCE: My Onkyo tx-sr606 7.1 receiver turns off by itself

hi, when the unit shuts off by itself, it means that the protection circuity inside has been activated. it can be a problem with the receiver itself or it is just detecting something hooked up to it that can cause possible damage so it shuts off.

you would need to disconnect everything from the back and by itself, try to turn it on, see if it will stay on and then crank the volume way up to max. if it stays on, the receiver is ok and you then need to rehook your devices one by one starting with the speakers until you determine the one causing the receiver to shut off.

however, if the receiver shuts off and won't turn on even by itself, it means that the problem is internal and it either has to go back to your dealer for an exchange or it has to be sent to a repair center for servicing.

hope this helps a bit.. ^_^

SOURCE: I turn my Onkyo TX-SR600 receiver on. After a few

The most common problem found on FixYa for Audio Video Receiver's is:

My receiver say's "Protect" or turns on then off. What's wrong? Seven times out of ten it is a shorted speaker or speaker wire. To determine your exact problem, the first step is to disconnect all speaker wires "at your receiver" Next: Turn the receiver back on. If your receiver still says "protect" or turns off, it needs to be serviced. If your receiver stays on; reconnect your speakers one at a time and power back up after each speaker. You may find that after reconnecting all speaker wires it works! Most commonly the small braids of wire from the + to the - have touched and have caused the problem. In some instances, you noticed the problem only when turning the volume up. either way, make sure the exposed wires to your receiver are no longer than 1/2" long and are completely under the screw down terminal or slide in. When you've found the wire or speaker with the problem, your receiver will go back into "protect" At this point, disconnect the wire from the speaker at the speaker that may be causing the problem then test again.* Note* Make sure speaker wires do Not touch each other as this Will cause a short! If you turn the receiver back on and it stays on, you now know the problem is in your speaker itself. To test your speaker, you will need a multimeter. Set it to ohms resistance and touch the speaker terminals, if there is a short internally the meter will read "1......" If it's an analog meter, it will peg to the right. There's your problem. Now, within any speaker there are quite a few possibilities as to what could be causing the problem. Most common is a blown coil and the speaker needs to be replaced. Some speakers have internal crossovers (usually floor standing speakers) and may have a shorted or burnt board (usually very visible brown burn marks on the board) and can possibly be repaired if your handy with a soldering iron. Now, if you disconnect the speaker wire at the speaker and it still says "protect" Check your wire for the obvious cut or nail thru the wire if possible. If your system has wiring that runs behind walls, you may need to use your meter again. Disconnect the wire at both ends, keep the ends separated, put your meter on ohms resistance and touch probes to the + and - wires at one side. If the meter pegs to the right or reads "1...." the wire is shorted and needs to be replaced or repaired at the short. Hope this helps.

SOURCE: my onkyo receiver (tx8511) keeps going to protect

Hi there
To answer your question;
Your amplifier goes into protect mode when it detects a fault or condition that could damage the speakers and/or the output stage.
Often caused by shorted outputs.
Although this does`nt tell you much on how to fix this problem, the best help i can give you at this point is to tell you to have it looked at by a repair shop.
Hope this help good luck
