SOURCE: Denon AVR-1508

If your amp looks like it's going to work as normal (ie the front display lights up as it should etc), but then the amp goes into protection mode when the anti-thud circuit times out, then I know what's likely to be wrong.

It's one of the power amplifier channels which has gone faulty.

I just found this out after having this problem with my AVR-1906.

I took the amp apart and de-soldered the suspected channel power transistors (centre channel in my case).....and hey-presto! it fired up as normal (obviously the centre channel would be out of service).

I have ordered the replacement transistors from Farnell (UK) at a miserly cost of around £2-£3 each.

Just waiting for them to arrive.

An alternative is, if you don't use all your channels, take the transistors from a known working but not needed channel and swap them over with the duff ones.

Hope thats of use!

SOURCE: Denon AVR 1804 Switch on and

try to reset it

To re-set the 2802, just do as follows:

1. Switch off at unit's main power switch.
2. Hold A & B buttons and turn power back on.
3. Check entire display is flashing at approx. 1 second intervals, release the 2 buttons, microprocessor is now initialized.

Hope this helps.

SOURCE: Denon avr-1804 its turns back after 5 sec

Disconnect all speaker wires on back and then turn on. If it happens again, it's most likely a power supply problem. If it doesn't happen again, it was probably crossed speaker wires.

SOURCE: Denon AVR older receiver but worked fine; now

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.

SOURCE: My Denon AVR-75 seems to stay in standby (red standby light is on) and I don'd get surround sound through it. How do I get it out of standby?

if the receiver does not power on from standby there is a problem like bad power supply or even bad macroprocessor. You need to bring it to a service center for diagnosing. 10-years old receiver, maybe better to buy new one.

I have a old denon avr-1804. try to switch on power but can not. just appear a main power red light flashed rapidlly. please tell me why?


Greetings
the red flashing LED is that the Device is in protection mode.
the internal power supply . +15 volts and -15 volts are defected you need to be replace it ... Regulators 7915 and 7815 .... these you should change , might also need to check capacitors .
these are common defects for Denon . AVR units.
Good Luck
Hope this helps

Denon AVR-3200 wont go into standby mode


Not sure what you mean by standby mode. The power button on most of the audio remotes I deal with merely turns the equipment on and off.

Zone 2 on my Denon AVR 1804 only works with an analog input. Apparently it was designed that way. WHY?


Because in order to use a digital input, the unit would have to completely power on. Zone 2 is designed so that it can be used with the main power off.

After turning on the power, the system shuts down and the power light flashes rapidly


I have the sample problem with my Marantz SR5300. Luckily I found a kind of KIA7915PI with metal backplate and I attached a small aluminum heatsink to it. So far so good.

My receiver keeps shuting down when i turn it on


Denon receiver has a common problem, keep shuting down after power button press, then red light blind. mostly, if none of amplifier output transistors blown, it must be IC7815 or IC7915 mulfunction, find it, replace it. then job down

Unit keeps shutting off


Protection circuit activating. Possibly a shorted amplifier channel or power supply fault. Take it to a Denon repairer

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
