Dear Sir,


First of all

I WISH YOU ALL DENON GROUP, STAFF & FAMILY

Now sir, coming to the point, i had DENON AVR 2802 , AND IT WORK VERY WELL SIENCE LAST NOV, BUT AFTER THAT I HAD PROBLEM IN ITS WORKING.

Receiver comes ON normally, Display is comming Ok.,All the functions are working O.K., except Volume. VOLUME display is varying on the penel, while operated.

When Unit 1st swith on, very low sound can be heared in the headphones and front Left & Right Speakers, and the moment any function is operated , volume cut off to ZERO & does not come on unless unit is swithed on again.
SOUND INITIALLY IS COMMING LOW ON FULL VOLUME, DISPLAY REMAINS ON even the sound is not comming .

We tried replacing EXT IN AV UNIT (1U-3369-1) board.Checked all the supply voltages on power unit (1U-3368-1), FOUND NORMAL.


ALSO CHECKED ALL THE POWER TANSISTERS ON POWER UNIT.

NO BURNING COMPONENT OR BURNING SMELL IS OBSERVED.


SIR, Its my earnest request to guide me and help me to solve this problems, as you might be aware of this problem, and how to solve this problem.

Your early reply will be highly appriciated. and even that will maker our life alive with DENON music.

Thanking you in advance for doing the needful

Truely yours

In general, you should try resetting the microprocessor on any Denon receiver if/when you notice a problem especially when it may seem rather odd. (no obvious defects, while not operating properly)

Resetting procedure is similiar between the models; 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. Youll 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.

If resetting did not have an effect, then problem is more likely in volume control IC or it could even be the processor itself.

(Not affiliated with Denon in any way, but can tell you that there is not much tech support,, if any available from them)
-------------Happy New Year To You Too
