try to reset. Unplug the unit, press and hold speaker A and speaker B buttons and plug the unit in outlet. If doesn't help, the unit may have a problem with microprocessor or dsp boad and need to be serviced at a repair shop.

Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

Have you selected the speaker option correctly. There are two button on the front panel labeled Speaker A & B. Select any one or both and see if you get sound. Make sure there are no objects pushed into the headphone socket.Test while playing a tuned radio station , make sure the tuned light and stereo indicator is on,that way we can rule out wrong connections at the back. Last - you wont hear sound if the Tape Monitor switch is on.

Check for loose speaker connections as a root cause for intermittent shutdown.

This is an indicatin of a circuit overload condition and is being handled appropriately by the protective circuit built into the output side of the amplifier. Have the problem fixed by an electronics shop to avoid blowing out or burning up your speakers and headphones. One thing to check at home is to make sure there are no shorted wires to the speakers you are currently using. Try different wires and a different set of headphones.
Hope this helps.

hi,

Sometimes reset will solve the problem.
1)On units without the Master On/OFF button.Unplug the power & while pressing both speaker A&B buttons simultaneously, plug in the main power cord. You will notice the entire display would start flashing as long as A&B is held on.Allow it to flash 3-5 times & release them. Unit is now reset to factory presets.
2)Check the volume control IC.
3)It is the problem with loose connection to with the DSP Ic.Just re-solder the loose connection.
If still the problem persist just replace it.Change IC, AT49LV002-70TC (IC 817 ) at DSP board



Please do rate the solution if the issue is resolved or post a comment for further assistance.


Thank you for using fixya have a nice day:-)

Set the receiver for auto audio input - I think that you are getting caught out between MPEG and DTS audio. If you have the wrong one for the audio source then you hear nothing.

Denon AVR-2802 | Answered on Jan 02, 2011


make sure there is nothing wrong with the cords and make sure they are plugged in right and if it still doesnt work then take it to the store you bought it from and make sure to have the reciet and then they should give you a new one

check speaker conections. disconnect all the speaker wires and use one speaker that you know that works and connect it to each channel one at a time. most surround sound stereos will not go into surround mode unless all the speakers are connected so make sure stereo is in 2 channel mode to start testing. check all fuses sometimes amp fuse is seperate from power circuit and denon uses relays in 99% of thier units.

This is where Denon suffers.... I am also not very impressed with Denon's service. Good products..bad after-sales.

If its AVR 2802, you must have bought it some time after 2002...
Are they not legally bound to stock parts for a certain number of years...
You must speak to their seniors in Sales department and if possible, please check locally, take them to the consumer court.
alternatively,
Ask them for the part name and the part numbers, you might be able to source it from somewhere else.
Best of Luck

The processor that creates the surround is all on 1 chip so sounds like a software issue.

Call Denon to see if they have a firmware update for your unit this usually is free and may fix the problem

Try doing a factory reset by turning off main power switch.hold down speaker a and b buttons while turning on main power switch ,display will flash 3 time s then release buttons,this then returns unit to factory default settings.

If the light is staying on after you unplug the AC power this means you have a short in the loop some where that is giving power to the receiver.

Try unplugging all connection to the receiver except for your speakers. Next hold down the power button for 45 to 60 seconds. Doing this will clear the flee power off the system board. Next plug back in the AC adapter and the receiver should turn on. If it does not then there is a problem with the receiver it self. If you did have a device shorting/grounding out to the receiver over time it would have damaged the receiver.

Let me know how things go

Actually, Denon used a thermal fuse in the primary of the power transformer. Have a tech check the primary winding and see if it's open. if so , have it bypassed

I had also the same problem. If you see the "digital" sign blinking on the display, it means the DSP to not start properly. You need to change the IC, AT49LV002-70TC (IC 817 ) at DSP board (Denon P/N 262 3010 006).
