Denon avr 2802 no sound on speakers but "works"

Hi all.
Any one have the good flash content or it is okay just to read the old flash and write it in a new one. Thx.

You can try this. It is not sure that you can read the content form the old flash or not.

Thx.

Team,
I had to wait for parts but got back to the receiver. I replaced the DSP first and no change, then I replaced the flash with the duplicate hex code loaded (checksum correct for the 4M part) and no change either. Exactly the same symptoms.

I tried to read the old flash and the programmer reported about 7 or 8 pins with a problem. The checksum was wrong but some of the code was correct. From that I can assume, the flash has some hardware errors.

I may be able to rule out the DSP and Flash at this point, but would need a bit more troubleshooting to be sure.

Any other ideas to try?

Thanks

Hi,
seems that no one try to push the " Input Mode " Button. When you klick one time through all the available Inputs, the problem is solved. Got the same problem 2 times in more than 10 Years with this AMP and nearly getting crazy about this bug. Really cant remember why and when this appears....sometimes there is NO Sound. Try it. Good Luck.

This remembers me a wedding DJ which was complaining about a mixing desk where the left Cd was playing louder than the right one. He phoned me at ball-midtime .. i have a problem.. I have to set the gain at max in order to have the same volume... so I grabbed some XLR cables and another mixing desk and drove to the venue.
Well... it turns out, it was the desk's crossfader not set at mid position... and he is a professional DJ / animator.

Another guy filmed three weddings with a broken camera. We had to un-calibrate an expensive Sony professional camera in order to recover / dub the movies recorded on tape.

Здравствуйте.у меня такая же проблема с ресивером DENON Avr-2802 нет звука на выходе. Не могу найти прошивку или уже запрограммированную микросхему AT49LV002-70TC.

Hello I have the same problem with the receiver DENON Avr-2802 lost sound on the failure of the memory chip AT49LV002-70TC. Could you send me a firmware of this chip or a new stitched chip

Thanks for all your seriously good advice. I have the same issue with my 2802. Would you be able to send me one of the chips so I can replace my faulty device.

Thanks

Hey guys.
As of today I have the fix for this. Took me months to do it, but now it's finished.
The problem is the flash chip on de DSP board. I has to be replaced with a working chip.
I have those chips 🙂 After replacing all is OK.
I can service the board , or send the chip, so you can do it yourself.
Mind you, it's a tricky solder job, not for the faint of heart 🙂

Regards, Henk
