Denon AVR 800 went into "Protect" now "Standby" light just flashs

I have a Denon AVR800 receiver that one day it would not turn on, it just would say "Protect" I checked all the speaker connections and they were fine. I left it alone for some time now and now I turned it on and something clicks inside (like it use to) but now the "Standby" light just flashes. Any help would be greatly appreciated.

It's going into protect. Unhook ALL the speakers and see if it still shuts itself off. If so, then it will have to be taken in for service.

sounds like overload protection
turn the volume all the way down, then turn it on
if that doesn't do it you may have a short in one of the speaker lines - try disconnecting them one at a time

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.

Did you try to reset the unit? Resetting the unit has fixed every problem I have ever had......turn off unit.....hold down A+B at the same time then turn the unit back on...hold buttons for roughly 3 seconds....Let me know if it works.

No power output or display.green standby light flashes.


Sounds like either a blown mainpower fuse or the thermal fuse for the power transformer. If the protect circuit was kicking in, the display would light up, but then turn off with a red blinking light. the green light with no display means the transformer is not getting power.

How do I adjust the surround sound without the remote?


I was able to find a manual for this receiver at this URL...

http://www.devicemanuals.com/productsupport/Denon_AVR-800_manual.html

Its a free download. I did a search through the file and there is a way to do this. Apparently, the remote for the AVR800 doesn't allow you to adjust the rear speakers anyway, so no problem about no remote.
Hope this helps...post an update if it does or not and I'll keep searching for an answer if not.

Denon AVR-1908 won't power on


Are you getting a standby light at all? Is it flashing? Do you here a click when you plug the unit in? If the answer is no to all of these then you blew a fuse. If you do have soome sort of standby light, then your set is in protect mode. More than likely for a blown channel. If no lights, but you ar egetting a click, you could have a bad transformer. Use a DVM and see if it is open or not. Good luck

After turning ON the power/standby switch, the unit(receiver) display comes ON (green light) then after approx.4-5 seconds the display goes OFF and the unit defaults back to the standby mode (red light). I...


Is the red light flashing at first?
The unit may be going into protect mode. Lets hope it has done the job and the receiver has protected itself from failure.
Protect mode can result from speaker wires touching each other or the Amps2_bing.gif metal case. Check that first.
It can also be caused by unstable ohm loads if too many speakers2_bing.gif are connected to any of the outputs especially zone 2.
If you can remove all speaker wires and turn the unit back on. If it stays on, turn the volume down on the main zone and zone 2 if connected. Then reconnect speaker wires.

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?

What failed component causes protection error message to display right at power up.


well, i just got this thing from a friend. its a Denon AVR-800. when powered up it displays the stops, just before finishing a -protect- shows up. There's a little red light standby light that blinks off and on also. i think that has to do with the internal problem. any suggestions?

Denon avr-2106 problem!!!


You're drawing too much power from it. Sounds like maybe your sub is hooked up wrong, double check that.

Stuck on standby


Unit is in protect mode there are a few problems that can trigger protect mode the most common is blown channel (shorted outputs). Sometimes one of the 15v regulators may go bad causing imbalance of supplys triggering protect mode. Also sometimes a bad solder connection could cause unit to go into protect also. I work for Denon authorzied repair center in Michigan if your nearby and Shipping to Michigan is economical let me know kstahl65@att.net
