Denon AVR 1905

"display not lit and power indicator flashes for 30 seconds then goes steady"

first thing I did was look at the trouble shooting page of the manual.

Disconnected everything and let it stand overnight.
Plugged it back in next day with same result.


Any ideas ???

Re: denon AVR 1905

Hello. Tonight I got the same problem with my AVR-2802, after listening to Sheryl Crow, and Too Slim and the Taildraggers at very high volume for an hour or so. Nasty smell and really hot transformer at shutdown. I removed the cover and checked for visible damage, found none. Checked the power transformer with an O-scope, and am getting only 1 to 2 V peak from all the secondaries, with the full 177V peak on the primary, with secondary plugs either all connected or disconnected. Also with secondaries all disconnected, I get the same symptoms of no display, standby power lamp only. No bad fuses. I suspect the power transformer has gone out, am searching for a service manual. The power transformer is about $120 US.

It happens sometime with low voltages. Try putting in a voltage stablizer in the path and test it. If it works, get a high quality component to give you correct voltage.

Receiver blowing fuses

Problem is most likely shorted output transistors. These are the large transistors mounted on the heatsink. When these go short, they usually take out some the adjoining resistors in that channel.

This is where a circuit diagram would come in handy, displays are tricky to trouble shoot, and this a job for a pro.

It appears that the protection circut has activated and will not reset itself. did what the trouble shooting measures asked and still will not reset.

When you turn on the Receiver if after 4 seconds you hear a click and the standby light starts blinking - it indicates an output short circuit. You will need professional help to replace the components because modern AV receivers have very complex construction ( multiple circuit boards mounted on one motherboard and a lot of interconnecting cables )

I have an avr 4800, and eveytime I raise the volume to -21 or higher it goes into protection mode. can you help? my zipcode is 60184

I'd treat this symptom as "DISPLAY not lit and power indicator is flashing rapidly." under Troubleshooting on Page 60.

and I'd evaluate the speaker load you're presenting to make sure it's effectively higher than 6-0hms per speaker channel.

AVR-1802 5.1 Channels Receiver: My Denon AVR-1802 LED is flashing rapidly. I have...

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?

When i power on the device, it comes on but goes off about 5 seconds later.


1st thing to check is for GOOD speaker connections at both ends
and not mixing A and B speaker wiring.

A Denon is usually a good brand. Might be worth servicing if need be.
