SOURCE: Denon AVR-1508 Receiver problems - cuts off and goes into protect mode

Usually when the unit runs for a while before shutting down there are two possibilities:

1) There is a small amount of DC current present that effectively heats up the speaker coils enough to cause a temporary short circuit that kicks in the protect circuit.
2) The output transistors or bias transistors are sensitive to heat and breaking down again causing the protect circuit to kick in.

A few experiments to try:

1) Does the time to shutdown change depending upon the volume level?
2) Is there any background noise coming from the speakers? Listen to a blank tape for example. Is there a hum or any other noise that you would not normally expect?
3) If you have a DC voltmeter, check for any voltage between the speaker lines.

Update this and we'll try to narrow this down.

SOURCE: ''Protect'' mode on Denon AVR 800

Protect mode appears when there is a problem with the amp it goes into this mode to avoid any further damage to the system. to begin with disconnect all the speakers and see if it continues or else it could be that moisture in the circuits have caused it to go in protect mode or else ther is some shorting in the circuitry. It wud be wise to have it serviced by an authorised personnel

AVR X1000 going in protect mode?


If you used it for only 3-4 hours before the problem occurred then you should have a replacement warranty on the product.
I think you have already done the factory reset procedure shown on page 175 of the user manual.
Is it possible to take it to the place you purchased it from. Alternatively check the Denon website and find out who the closest agent is in your locality. Send it back with proof of purchase using a courier service that you can track for receipt. Hope it turns out well.

Denon AVR-1100 receiver "PROTECT" mode


replace all the electrolytic capacitors in the power supply. i had the exact same problem with mine and once i replaced the capacitors it powered up and stayed on and worked perfect.
these capacitors tend to fail as they're of poor quality.
this fault is very common on denon receivers, especially the later models.

hope this helps?

Says protect


Probably some speaker wires got shorted or the output stages freaked out and the cpu went into protect mode. Normally plugging it out of and in to the wall socket should/could reset it.

First check all wiring at the speaker outputs and on the speakers
then if it still wont startup you could try the avr-1500 method with
some trial and error pressing of buttons.

avr-1500 reset method:
Unplug the unit from the wall, hold down both video select and audio select at the same time, plug it back in. Keep holding both buttons for 2 secs, unit will reboot. As you have no audio select button on your avr-1100 you might try pressing video select and another key to see if this will reboot it.
