IT'S ALIVE! DSP errors gone and sound beautiful sound on the outputs. new member here, I joined because I have EXACTLY the same problem with my denon avr-x4300h which from all the photos I find has exactly and I mean EXACTLY the same boards and parts board part numbers as your marantz I have DSP2 ERROR 1 The firmware version number displayed in the screen gui has digits but the DTS version is 0.00.00.00 as per yours also when I view all the version numbers (the full screen display after poweron+ setup + dim buttons) they're all populated EXCEPT DSP1 00.00 DSP2 00.00 DSP3 00.00 DSP4 00.00 All other fields as I say populated appropriately
I wonder if you could give the precise eeprom part numbers that you ultimately used so that I might order the same What was its price and where did you order it? It looks like I'm going to have to do a similar job ... de-solder, program and resolder but I think I'll swap out all 4 of the eeproms (1 per dsp chip) In case anything that damaged the dsp2 eeprom also weakened or damaged the rest any further advice or words of note would be appreciated Kind regards Jeremi |

I will answer for now since I dont know when mmartell will be back.
iirc, he found an error in the DSP3 flash code. He corrected the code based on data from a read of the other DSP flash devices. But the original flash ic was not programming properly. He tried another new flash ic and it worked temporarily and the receiver worked but only for a short time and then gave problems. So he went back to the original flash ic and it programmed correctly and then functioned properly in the unit and that is how he left it as far as I know.

I will be very interested to hear (when mmartell gets back) how long the old eeporm lasted of if indeed it caused any further problems
It might be the case that I too simply have a corrupted memory location which causes the program to be inoperable, and it just needs its contents restoring
I read in the thread that he had DSP3 ERROR
In my case it's DSP ERROR 2 (as the first reported error) though I have after reverting to factory firmware seen DSP2 ERROR 7, it has since reverted to DSP ERROR 1 again when I *updated* via the internet. And stayed as such now.
I'm hoping that my solution will be the same.
Do we have a notion what might have caused the corruption in the first place?
My worry would be that it's a sticky bit or a non responsive bit location (or a few) in the memory chip which only by sheer chance matches the 1's or 0's that should be there for a couple of reversions back to factory firmware or updates via the internet after that our luck will out and we're back to faulty operations.
This is why I would be very interested in replacing the suspected chip.

NM I see it on page 197 of the SM. No matter, last night I replaced the original flash on the programmer and it was recognized, reprogrammed and verified in under five minutes. After reinstalling on the hdmi board the unit survived both the Factory Restore and subsequent Firmware Upgrade processes. As this is going to be a personal unit and considering the fault/remedy is known I am going to consider this done. I am not yet ruling out obtaining and replacing the macronix flash with a new one but the time has come and I need the space. Thank you mastertech and srt for your insights and guidance. as you know I've been reading and following your journey with huge interest
A friend is looking at my denon (same board and chips) and despite having a slightly different DSP2 ERROR 1 reported all the 4 disp firmware versions are 00.00 like yours
turns out on checking that dsp 1 eprom memory seems full and coherent dsp 2 eprom contents is identical to the file you posted earlier
but dsp 3 eprom contents has empty blocks like you described
I wonder when you get back if you could please post the modified (corrected) dsp 3 file so that I might try that in my amp
Indeed if you could post all 4 good files that would be useful for completeness
cheers Jeremi

Hi sorry just saw this, was busy with other things for the last while.
mastertech is correct in his summation.
The unit has left the bench was not touched since so I can't vouch for the veracity of the fix. I too wonder how/why the flash became corrupted and seeing as you may be having the exact issue it's likely not even random at least in some respects.
I thought I did post all four dumps in this thread let me have a look back first then will respond.

Here are all four bins in order 1 through four for completeness.
https://www.dropbox.com/s/r5f1a73hhfzha9m/Marantz%20DSP1_IC254.bin?dl=0
https://www.dropbox.com/s/u6ny3jks28cus0g/Marantz%20DSP2_IC264.bin?dl=0
https://www.dropbox.com/s/utsvwonepczumcu/Marantz%20DSP3_IC273_patched.bin?dl=0
https://www.dropbox.com/s/kaeeesobmetk9eu/Marantz%20DSP4_IC283.bin?dl=0
You'll notice all four bins share the same boot code (first part of dump). That's what was patched into the DSP3 flash as it was missing a large part after a few lines.
Let us know how you make out. Cheers

Btw don't forget to do a Factory Restore as that will force all firmwares/flashes to be at the same level.

Thanks for posting those
Indeed I too wonder what might be the common factor which may have caused the seemingly identical error
My friend doing the fix for me reports that audio has returned, and all the dsp versions show actual numbers, he's restored to factory firmware, and updated again over the internet.
It turned out that it was dsp3's eeprom which contained the missing bits/byte, coincidence ? good question.
In case it's a damaged memory chip all 4 are being replaced by new ones of the same type.
I will keep an eye on this amp and report any developments.

Good news and I would guess this is a firmware bug and not hardware related considering it's highly unlikely any defective chips would end up only in DSP3 location.
Sample size is quite small though, lol.

I'm due to receive my Denon back by post shortly so I'll be able to report back to firmware / dts version numbers etc

but last night, while watching a dvd at the start there was no audio, I thought it might be the dvd itself
but today again I have no audio again.
once again the DTS VERSION SHOWS ALL ZEROS
Have you had any further problems?

No further problems here but I only turn it on occasionally. I have been prompted I think three times to do a firmware update and have taken all three without incident. Can't say if any of those updates have written to the dsp's I suppose I can look back in the thread and compare ....
Seems odd to lose sound while in use. Did you reuse eeprom or use new ?

I had the same issue with my SR7011 last week. Not sure what was the cause. I did lose power and had some fluctuations but between the Panamax 5300 surge protector and the UPS the receiver should not have seen any spikes. No preamp outputs nor sound from the the receiver amp outputs. If you ran the speaker setup manually or using Audyssey it would lock up on the first speaker. Multiple factory resets (Game & Info buttons pressed while powering on) some simultaneous did not fix the issue. What did fix the issue for me was the 'Firmware Regression (Factory Restore)' (M-Dax and Dynamic EQ pressed while powering on). This is from the link you provided on page 2 from Marantz. Thank You! It took about 20 minutes for the restore to complete. After that, I had sound back. Since then I updated to the latest firmware without issue. I thought I might have a $3000 paper weight and wasn't too pleased. But now I'm happy again. Thanks again for the suggestions at least I didn't need to replace any chips.

I'm also having nearly the same issues with my x4500h. photos.app.goo.gl/4D1csqgEJ96brbr98Unfortunately, I don't have the skill level you guys have but I'm learning. Certainly not the tools. I tried my damnedest to get a firmware file from Denon and my call is escalated. Obviously they have the ability to do it. Hoping that I can still just get a firmware file and take it back to stock because there is no sound and no GUI. Making me suspect a bad update (WiFi, and, I learned my lesson). I'm hoping that it is a firmware issue because no sound and no GUI that are on different chips. Also, it won't go past 61% of the factory restore without throwing a 1202, 1302 and 1902 error on a factory firmware restore. So from my photos, what would you think? Should I get a board from encompass or continue to try and find the firmware? Unless any of you are in Phoenix and like to help out, I can only get the board. Thanks for hearing me out. |
