Re: Denon avr 2802 with no sound on speaker

It's still thanks to you, it was you who started ...
I couldn't have flashed without your 256 KB file.
Thanks again.

Re: Denon avr 2802 with no sound on speaker

wow, that is a really impressive & creative solution, to use an Old DIP32-size FLASH memory in place of the surface mount type. I'm glad you were able to get this 5V FLASH to work at 3.3V.

Re: Denon avr 2802 with no sound on speaker

Hello,
I am a small French hacker, sorry for the translation ...
The idea for me was to repair my DENON AVR-2802 without buying a memory or programmer : maladroit:
In addition, orders in China impossible with Coronavirus.
Thanks to azchris for all the valuable information :clin d'œil:

I used an ARDUINO MEGA 2560 to program a W29C020 memory that I had in stock of the same size 256k x 8
A SPI mode SD card reader

I used the 256Kb azchris flash file, renamed to "HEX.bin" copied to an old 128MB SD card formatted in FAT32 or FAT16.
Thank you, thank you to azchris

For information, I tried with a 2GB SD card but does not work ...

I made sure to read the SD card by block of 0x80 Octect because the Arduno does not manage the 256K Octect at once.

The wiring details in the file "FLASH_DENON.ino"
For W29C020, a PDF file for erasing and programming procedures.
The procedures can be different on other Flash memory.
The W29C020 memory is in 5 volts but works very well in 3.3 volts on the amplifier.

It is not super clean with the wires but it does not bother me as long as it works well.

I'm happy, my Denon amplifier is coming back to life

I kept the old memory just in case.

Hope this can help someone.

Re: Denon avr 2802 with no sound on speaker

Hi azchris i have the same broblem with my denon avr 2802 (no sound) can you sent me
an already programmed ic chip (ATMEL AT49LV00270TC)?

[azchris]

Re: Denon avr 2802 with no sound on speaker

Glad you were able to get your Denon working again.
Anyone else looking for the FLASH IC, I may be able to provide it.

Re: Denon avr 2802 with no sound on speaker

My denon is working the Denon AVR-2802 is 100% fully working condition and special thank to AZChris who actually is responsible for the flash IC. i replaced both IC the DSP IC is easily accessible in the market but for ATMEL ic you need programmed IC. Or like AZCHRIS did. Just follow his procedure.

Thank you again azChris

Re: Denon avr 2802 with no sound on speaker

Ooh sorry just saw your post. OK ordering the DSP IC.

Thanks again.

Order the DSP IC from whereever you want and change that first.
If that does not resolve the issue, only then contact me and we can discuss
the FLASH IC.

Re: Denon avr 2802 with no sound on speaker

Man you are a life saver. rock on dude

I really really need to send you some voice note. Can you PM me your whatsapp number? I will alway be grateful and help anyway i can when needed.

I returned the AVC-3800 today and against that I bought the JAMO Center Speaker. Now all I need is the DENON AVR-2802 to work. Because its the only AMP that matches with my speakers aswell as the required Output wattage.

Its a must to have both the IC's because if if if if..... DSP IC is working and the Programming IC is failed then we'll be back where we started. even if its in working order after the DSP change, I'll atleast have a backup of Programing IC when needed.

I do have some cousin living in US. I'll transfer the amount to you and you can program the IC and send it to them, they'll bring it over here.

Cause I want this thing to work I loved at and we all did, my father is a audiophile listener and he loved the sound that denon AVR-2802 produced.

Appreciate all that you did till now

Thanks in advance.

I looked at the DSP datasheet and the -CLZ version simply means it's a lead-free package.
So it should work just fine. (See attached screen grab).
You can download the datasheet anywhere off the web but I've also attached it.
I didn't think paypal would be a problem but hey, order from whereever you want.

Re: Denon avr 2802 with no sound on speaker

I can transfer the amount to you and you can ship it to my address, would that be ok?

I don't know what, if any difference there may be, and also I'm aware that counterfeit ICs exist in the market so it is more risk to try a different one.
I don't understand why you don't order the IC off eBay, which I know works.
The price on eBay is $US 11.99 with free worldwide shipping.
The price on Aliexpress seems much more (~$25?).

Re: Denon avr 2802 with no sound on speaker

Kindly check as the cirrus logic. The vendor of the chips.
CS493292-CLZ is the chip

The issue is the paypal account. The payment method for international shipping is with paypal only that is the only issue.

Re: Denon avr 2802 with no sound on speaker

this is the IC available at Ali:

CS493292-CLZ not the CS493292-CL would it work?

--> YES, I recommend changing the DSP IC FIRST.

[azchris]

Re: Denon avr 2802 with no sound on speaker

Aliexpress does have Crystal DSP IC. You recommend to change it first?

Re: Denon avr 2802 with no sound on speaker

Its a different model not AVR-3802, Its AVC-3800 which is quite an old model.

denon AVR-2802 issue is: No sound in analog or digital inputs.

The Optical line use to detect my signals as Digital after no sound issue It does not lit the light of DIGITAL Signal.

But it does detects my Optical link.

at full volume I can hear the sound coming out of my speaker as low as headphones

I have the option to return the Denon AVC-3800. I will return it because it sounded terrible.

The main course of issue is the installed firmware "Macronix IC". If you can send me the programmed firmware IC, I will try to find and buy the Crystal IC from Aliexpress.

I think you are saying that you don't like the AVR-3800.
Funny, I also acquired a Denon AVR-3803 from a friend who had damaged it by ESD (Electro Static Shock) event, and that resulted in two Blown ICs on the Input board (Toshiba TC9274N). After replacing those, and two blown power supply fuses, I was able to repair the AVR-3803.
It works now, but there is one thing I don't like about it: When used in the DSP modes (such as Dolby) using a 2-channel source (e.g. Tuner (Radio), CD In, etc.), the DSP effects seem to distort the sound going to some of the channels.
The AVR-3803 uses a different DSP compared to the AVR-2802/982.

Assuming your AVR-3800 is similar to the AVR-38023, Maybe you should try switching the AVR-3800 to use the "direct" or Pure mode (one of the non-DSP modes) and see if that solves your sound issues. In direct modes, without any DSP processing, the sound is pretty clean thru all channels.

[addahasan]

Re: Denon avr 2802 with no sound on speaker

I tried with both Optical link and the Direct 2 Channel mode. Both sounded like a speaker that is put inside a box. low quality treble.

Will international shipping is an issue. I found some site they cost around 18$ for shipping.

As mentioned in earlier post by dbdenon, I tried it, and at 18+DB volume i can hear the music lightly coming out of my speakers.

So my conclusion was the same issue as DBdenon mentioned.

Re: Denon avr 2802 with no sound on speaker

I bought the Denon AVC-3800 after this my Denon AVR-2802 gone bad in a single day. The 2802 matched with my system in the most outstanding way. The AVC-3800 is the worst experience with amplifier. Its the worst nightmare of Amplifier quality sound.
