hi, I have the denon avr 2310 amp. The last couple of days it has been cutting out. sometimes straight away and other times 40 mins later. what would you suggest is causing the sudden problem. some advice please if you can

Could be heat (does it have plenty of air round it?). Could be a stray speaker wire strand causing a short - check all the speaker connections to make sure the ends are neat. If those fail, could feasibly be a short inside a speaker, which can be a pain to diagnose. Otherwise is most likely an amp problem...

Does the red power light flash when it cuts out?

If so - Do you have adequate ventilation around the unit it may be overheating. The red power indicator light will flash at intervals of 2 seconds if this is the case, once the unit has cut out.

Also check the speaker connections that they are not loose or touching, this will make the red power light flash at half second intervals.

If the light does not flash is the unit loosing power, is the power cable securely plugged in, etc?

thanks for reply. Theres plenty of air around it, it's been in the same position for 2 yrs.I have heard that a speaker problem itself can cause the amp to cut out like you say( i'm hopeing it's not though) it's a tricky one.My rear speakers are connected together with two seperate lenghths of speaker cable, and have been for a while and it's never cut out, could that be the sudden problem i wonder. I hope you understand this next bit. Could it be - on my denon dbp-2012 bluray player i have connected annalog cables to the 2 audio plugs and have sent them to the cd area of my amp for stereo sound for my music, and the hdmi cable is sent to the dvd area of the amps terminals . Could they be clashing in some way

The red light flashes in half a second intervals or i'd say a second, the amp does'nt seem hot really. It's really strange trying to work out whats actually causing it suddenly

Thanks john , earlier i did connect the rear speaker cable again and put tape round them,and it cut out again about 20 mins later,( it cuts out when i've just got my hopes up) it could be the problem i spose but it never made the amp cut out before. It looks like i'll have to pull the amp out and check every coonection. I hate doing that it takes me about 3 hrs

Yes bummer indeed. Don't do it by inspection though, take each wire out and roll fingers round them to tidy up loose threads (if you're using bare wire as opposed to bananas). If you're using factory fitted bananas, you might be in trouble...

Had a glance at the manual and the 1/2 second interval relates to both a speakers problem and unfortunately failure of the amplifier circuit.

Have you checked each speaker cable at both ends - amplifier and speaker?

The speaker short could also be internal in the speaker cabinets

Faults vary, but the last one i mended (different model) had damaged driver transistors and emitter ballast resistors. Easy job but time consuming. I have no idea of the topography of your model in the O/P stages.

I also changed the reservoir capacitors as they were showing signs of stress and damage.

Hi,

My Denon 1909 did this after about a year, unplug everything from the amp and leave it out in the open.

When you have done that, plug the amp back into the mains and switch it on. Leave it on and see if it cuts out again.

Mine did and needed to be sent off to my supplier, when it was returned it had a software uograde as well.

It just strange that it cuts out any time it feels like it. Like i said could be 5/ 10 /30 mins or over an hour. If it was the speaker cables touching or something around that area i would hear a buzzing or crackling or something i would of thought. Can an amplifier cut out if the audio interconnects your using - interconnects for stereo music use, have been damaged etc.

just a return reply to john duncan . I'm using banana plugs on all of the speaker terminals and speakers.But the other day i took them of the back of the rear speakers so they are now bare wire, only on the back speakers though not the amp.

They can indeed. If you have intermittent connections on the input of an amplifier it can cause bursts of instability (too High frequency for you to hear). These bursts are stressful for the amplifier as it will clip at full power and cause it to cut out or blow up, which ever comes first.

If you have a day or two spare then remove all the cables from the amp and leave on for a couple of hours, (assuming it doesn't trip off) plug in the front tree and run for a couple of hours, (again if it doedn't trip) plug in the surround speakers and run for a couple of hours.

If it does trip at some point remove the cables again and then go one speaker at a time.

Good idea actually. From what you describe it does sound like the rears are more likely the cause of problems, take them out and run with just the front three and see if the problem goes away.

If it does, then the rears are the problem. If that's the case, do the reconnection stuff we've discussed already, and if it's still a problem then -as already mentioned - it could be the wires or the speakers. Difficult to try 'new' speaker cable with such long lengths but it might be worthwhile trying the rears with long runs of cheap two-core electrical cable to rule out an internal short on one of the speaker cable lengths. If that still doesn't work, you might be stuck with taking the back panels off the rears and checking for internal shorts there; for example, my 9.1s have internal connectors that can loosen and rotate internally, touching and causing a short.

I have'nt had time to pull the amp out and do some of the tests suggested. But i have removed the stereo innterconnect from my denon dbp-2012 bluray player which is running to my amp.which i use for music. When i've previously pulled the amp out i've accidently bent the cable a few times or more, forgetting to remove it. After removing it i played the amp with a film and i had it on for about an hour, it did'nt seem to cut out. But like i've said it can cut out at any time. I was trying to think what i had last connected to the amp before the problem started, as i've only just got the denon 2012 bluray player. That was when i had to pull the amp out AGAIN!

Had a similar problem with my amp and it ended up being a defective HDMI cable.
