Rx-v795a reciever shuts off after 5 min or more can not hear fan in reciever for cooling.


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.

My denon avr1200 receiver once it is turned on goes into Protection mode. How do you reset or make work?


The reciever will go into protection mode when there is a short in the speaker wires or the amplifier was overloaded. What I would do first is verify that none of the speaker wire connections are loose at the back of the reciever or at each speaker. And verify that none of the wires are making contact with each other. Then label each speaker wire as you remove them from the reciever so you can re-install them correctly. After you have disconnected the speaker wires try unplugging the reciever for 10 to 15 minutes. Most recievers have a self-resetting overload protection switch and this should reset it back to normal. Now try plugging the reciever back in and turn it on without the speaker wires connected. It should be out of protection mode now. If it is still in protection mode verify that there is not a reset switch somewhere on the back of the reciever. If it is not in protection mode now then proceed to connect one speaker set at a time and turn on the reciever to see if it goes into protection mode. If it goes into that mode after connecting a speaker then that speaker is the cause of the problem. If it does not go into the mode after all speakers are connected then try turning the volume up. If it goes into protection mode then there could be an internal short on the amplifier or a incorrect OHM rated speakers connected to reciever. Verify that the speakers are rated the correct OHMS.

I have a new house that had speakers built into the cieling. I bought an onkyo to push all eight speakers. the reciever went into protect mode. i had an old reciever and hooked four speakers to the onkyo...


you can check them with a ohm meter, hook it to the wires that you hook to the reciever and if you get a reading it is good if no reading it is bad wires

My stereo keeps saying ''protect''. how can i fix it? ive tried to unplug it for 4 hours and it still dont work


Check the speaker wire connections and make sure that none of them are crossed. Shorted wires will cause the reciever to turn on the protect mode to keep the amplifier from shorting out. Try disconnecting the speaker wires from the reciever. if you turn it on and it still says "protect" then the short is possibly in the reciever itself.

Protect displaying


Protect on any reciever usually means that it has reached its maximum capacity of volume (known as clipping) and at the reciever is now automatically reducing the volume to avoid damage. This some times is triggered if the reciever was used hard and is now damaged so you would need to bring it to a repair shop. Sometimes its caused by a bad wire to the speakers, a short to say. Check all your wiring, make sure its not overheating and getting plenty of air. Some where its recieving a signal telling it to go into protect mode.

Receiver shuts off when volume raised above 10


A fuse breaker or resetting electronic componet device attaced to the audio receiver protects the amp & speakers for destruction! The quality of the amp ,spkers& spks. wires help on choosing for protection shut downs! Of course at 10 volume you risk all of the amp in the receiver , buy a higher quality brand reciever ,intergrated amp, single amp . BE CAREFUL AT THE HIGHER VOLUME RATINGS YOU RISK HEARING DAMAGE! FOR REAL!

Protect mode turns the reciever off at fairly modest volumes


I Had the same problem.

It occurs when you have a speaker wire touching something that it shouldnt and and you are grounding out the system. The system is going in to protect mode to keep itself from being damaged

In my case I found that I had a couple of frayed wires from one of my back speaker terminals touching the wire on the other terminal. This was all it took. I re-inserted the speaker wires on that one particular speaker and made sure they were not touching and problem solved.

MY AMP KENWOOD VR-206


that is not a problem. i have the same reciever and it has done that since i bought it. i read up on it and it is a protection feature in case you had the volume cranked when you turned it off it gives you 3 seconds to reduce volume before the amp turns on. that is why you may hear a click when the mute turns off. it is also known as soft clip because if the amp would turn on at the same time as the reciever it could cause a surge to the speakers damaging them. it is a feature not a problem.

Reciever turning off.


You have a short in the speaker wiring. Simply put, the pos and neg (red/black ends) of your speaker wire are most likely touching somewhere. The receiver has a short protection circuit that keeps you from blowing the receiver or your speakers. Either try re-cutting the ends of the speaker wire, or if that doesn't remedy the issue, buy new speaker wire.
