I have a new RX V661 7.1, shuts down when I turn it up.
Just hooked up my new receiver, keeps shutting down when I turn it up. I reconnected the wires to the back of the receiver, to make sure that there was not any wire touching or sticking out. Appears to be all clean in the back, but still shuts down. I have JBL in-wall speakers, have not pulled them out yet to check, but don't think that the connections at the speaker end is the issue. What can I do?

You have to read the manual about 4ohm speakers 6ohm speakers and 8ohm speakers. Im not familiar with your problem but i know its saftey feature so the receiver wont overheat. Hope this helps a little.

The amp protection circuit has been activated. Remove the power cord from the wall outlet immediately. Disconnect all speaker cables and input sources, and leave the AV receiver with its power cord disconnected for 1 hour. After that, reconnect the power cord and reconnect an input and a pair of speaker wires onto the unit. If the receiver still does not turn on than you will have to bring it in for service. Turn up the volume and if the receiver doesn't shut down, power off the receiver and add another pair of speakers. Power up the unit again and turn up the volume. If it doesn't shut down, power off the unit again. Now connect all your input sources and turn on your receiver. If the unit shuts down again, your unit will need to be further serviced at an authorized Onkyo service center.
My first thought would be that when you moved the receiver to connect another DVD, the problem quit since the speaker wires moved. The best way to test would be to re connect the original unit the same way as the new unit and test again. If it still cuts out, disconnect the speaker wires and re test. if it still cuts out, try the new player and test again. if it does not cut out, there may be a problem with the old units audio output. Generally if its a problem with the receiver it would not matter what source you are using, even the tuner on the receiver, if there was a short in the receiver it would cut out. Let me know what your results are and I will help more if needed. Best of luck!
It indicates an output load problem, dis-connect the speaker wires from the back of receiver. Next power on and turn the volume right down, if the unit runs, check for shorts in the speaker wires and speakers. But if it still shuts down "with speakers and wires dis-connected" one or more of the audio output ic's is shorted and will need a professional to assess the item.
This is a common question on this site. Amps of all types have protection circuits to keep them from doing a self meltdown. Testing follows this logic.
1. Remove all speaker wires.
2. Keep the volume down - all the way.
3. Turn the unit on.
4. If it does not trip off, then there is a problem either in a speaker or the wiring.
a. Reconnect one at a time until/unless it trips off
b. That will tell you where to look further.
If it does trip off, then there is an internal circuit issue in the amp and probably requires professional help to fix.
If Both speakers are working at a low volume and you turn it up and it clips and shuts off you have one of 3 problems. you have over driven your speakers and one has shorted the voice coil but still will work at low volume, its a overload protection for ohms short in receiver. unhook each speaker and turn balance to the one hooked up and turn up receiver if it shuts off do the same with other speaker to determine which side is bad. 2 speaker wires are touching at speaker or receiver. 3 a bad receiver output transister. Good luck.
When a system shuts down after a few seconds it is the self protect circuit shutting down power to the outputs to prevent (further) damage. It may be caused by frayed speaker wires, bad speaker voice coils, or blown output transistors. First, turn off power and remove all speaker wires from the receiver. Turn it back on and see if the problem remains. If it works OK, inspect each speaker wire at both ends for loose strands and correct these. Then, hook up your speakers one at a time until the problem reappears. That speaker or its' wiring is your problem. For safety's sake. turn the receiver off before connecting each speaker. An accidental short of the output terminals can be disastrous (and expensive).
No, one of your speakers is damaged (could be an amp channel went bad, but speaker is more likely). Unplug all spkrs, then plug one in and see if it acts normal when turned up. Repeat this until all speakers are hooked up or the culprit spkr is found.
Unplug all the speaker wires first, then unplug the unit from the wall for at least 24 hours, The plug back in without the speaker wires or anything else plugged in. Then see if it goes to the protection mode. If it does not, plug in each speaker at a time, and see if any speaker, when hooked up, makes the receiver shut down. If it does shut down, My friend, I'm afraid you will need to take this unit into a repair shop, OR get a new unit. Good Luck
