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.

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

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: shuts off then red light indicator flashes, disconnected all speakers but still wont work

Hi, this is a power board issue. remove the cover and make sure that this unit doesn't have blow fuse. if the fuse is fine, you will then need to replace the integrated power/ main board.

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.

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-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

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.

ON/Standby Led Light flashing


Consider re-initializing the machine. Follow the instructions in Pg. 55 of the manual. Note: This will "erase" all your presets, so you'll need to go through the setup again.

Denon AVR 5803A upsampled digital inputs I had 2 questions you might be able to help me with. Both relate to my Denon 5803A signal processing. I have just purchased a Cambridge Audio Azur 840C CD player with both digital and analog outputs. The CD player upsamples standard 44.1 khz to 48, 96, 192 for digital output (and 384 for conversion in the CD player for analog output). The Denon is listed as having DAC's that operate at 192, yet when I upsample the CD digital output to 192, the denon switches to 'analog' from digital, and plays nothing through the digital coax input. If I take it down to 96khz, it plays (and lists as 96 PCM on the front panel when in 'auto' mode). So first question is how do I take a 192 khz digital signal into the Denon. I had thought the "A" designation/upgrade allowed for this. 2nd question - if I take the analog out from the CD player to the analog in on the Denon, does the Denon convert back to digital in order to 1) split the signal to the sub vs. the mains at 80 hz (or is/can this be done in the analog realm), and 2) play in 7.1 channel stereo (I know some signal processing happens for center channel, but I don't use this channel...so technically 6.1 channel). Net, does the left and right channels for front, side, and back have any signal processing in the digital realm on 7.1 channel setting. I ask because the CD player actually upsamples to 384 khz before converting to analog for a very good signal. yet I like a crossovered signal for sub, and enjoy 6.1 music at times. Thanks for any help you can offer.
