Question about Denon AVR-1905 Receiver

2 Answers

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

The device does power on, but when I push the switch to turn it on the display lights up and it stays on for about 5 seconds and then goes off. The on/standby button then just blinks. This unit is only 3 years on and I don't want to have to replace it if necessary. Does anyone know about this problem? If so, is it expensive to fix? Thanks for any help you can give. Ron

    Hi,

    I'm having the same problem, currently trying to find a Phillips head screw driver to see what i can see.

    I had my amp playing full volume at a party for hours and it started smoking and shut down.

    Now it comes on for 5 seconds smells a bit with a slight hissing sound then shuts down.
    I figure this isn't fatal otherwise it just wouldn't come on at all right?

    Ill have a look in and try to see what component is smoking.

    Any help would be greatly appreciated as Ive had quotes for about 80 quid for repair with a month turnaround so would like to avoid that is poss!!

    Thanks

    I have the Denon AVR-588. We've had it for about 6 wks. We went away on vacation for a week and when we returned it does the same thing as yours - powers on for a few seconds then turns off w/ red light flashing. We've disconnected all speakers and still it doesn't work. We've plugged it into the outlet (instead of surge protector) and still nothing. No other components are damaged so I don't think it's lightning/surge damaged. Our a/v guy is coming out tomorrow get it and send it in.



    Ron, did u have your repaired and if so what was the problem?



    Thanks!

Mine also went on protect mode after a faulty shorted connection..after making sure that all ics and transistors are okay,,ive changed the two huge capacitors on the power supply board ( 15000uf 63vdc x2) and my denon avr3300 flawlessly revived. i am now enjoying it again. this is a very nice receiver. good luck!!

You had a post that said you had fixed faulty power relays on DSP-a1 - how do you identify the relays that need cleaning?


That your amp does not go into the second stage of powering up indicates a fault which is causing it to sit in non-active mode. This could be due to blown output audio module or transistors or a fault in the safety circuit itself. It is not a fault the non-technician can repair and it would need to be sent to an authorized workshop.
I have seen situations where users unknowingly leave frayed ends of wire shorting across the speaker output terminals which can lead to this sort of fault. You could check this out also.

I hit the power button and then it comes on and two seconds later, it turns right off.


you most likely have audio output shorted, when that happens the unit goes into proteccfion to prevent furter damage, you must have it repaired

most of the receivers come with a cooling fan inside see if its working they usually work when you turn the volume up,, if its working that means you are playing it to loud if you lower the volume a little it will play just fine..( if the fan inside is not working thats the reason it goes into protect mode and it means you must have it repaired,, it goes into protect mode to prevent furter damage to the unit or the speakers,,

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.

I have a pioneer receiver..vs 812....and sound has ceased to come out of it. It comes on....and switches between sources...but there is no signal coming from ANY source


First make sure the speaker A/B switch is on.
If still no sound, dissconect ALL speakers from the rear of amp.
Now turn on amp and listen for the relays to click in.
One relay will click when you press power. A couple of seconds later, the speaker relay will click in.
If it does, you could have blown outputs, bad speaker wiring, faulty speakers.
If it does not, the speaker relay may be faulty.
Hope this helps.

Amplifier goes from low volume to high volume without touching any controls. I turn it down only to have it mysteriously go up again 5 minutes later. Warranty ran out one week ago...


Let's eliminate ghosts and goblins. I can't identify your unit. Give me a make and model number.

As a test, locate the remote control window on the front of the unit, if it has one. Set it up to watch or listen to something then cover the remote window on the unit with a small piecr of cardboard. If you can't locate its infrared receiver for the remote just cover the entire front of the unit with something sufficiently opaque to block your remote. Try to operate it with th remote to be sure the unit can't see it.

If the expected problem never comes back you have a stray signal from something else in the environment getting interpreted as a 'volume up' command. Then look around for other remotes being used, wireless devices, use your imagination. I used to have a remote-controlled space heater and my TV would sometimes shut off if I used the remote. Does the unit have line-of-sight to a nearby house? Maybe something next door (garage opener?) is interfering.

If it still happens and there are no other infra-red devices nearby you have a ghost.

Power on T743


Just had my t753 in bits... sounds like its overheating to me. Check that the fans on the bottom still turn and aren't clogged up with dust. Make sure that it has plenty of ventilation.

hmm, also try unplugging everything and leaving it on and see if it still freezes? ie check you're cabling is ok, there are no shorts from bare speaker wires etc...

Could try resetting it too? (in each case hold the buttons for 5 seconds then release)
- Firmware version: hold video 6 and tone control
- Reset DSP: video6 + tone defeat
- Reset completely: video6 + right source button (this will wipe all settings - hold for 5 seconds, release and then unplug from the wall or turn off with the rear power switch)

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


Hi...

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.
