Thank you

The LX55 is the same as the VSX2021 and VSX53.

You can download the latest firmware here:

Full Pioneer firmware to install from USB

[andyb1712]

Do you require the full Pioneer firmware to install from USB or the DSP file dump to repair a corrupted flash memory?

[Zicsal]

Please, anyone can share or post last firmware for Pioneer VSX-LX55?

Thanks for the photo and link of the chips you used. The one fitted to your board looks 100% fake to me, so I wouldn't bother trying to make this one work

The one you show next to it looks genuine but if it's from Aliexpress it will be a used one at best and at worst an old B revision marked with a D.

It's a big gamble buying these from eBay or Aliexpress because NONE of them are "100% brand "new as they claim. They are ALL lying because these chips were never available to the public, only OEMs like Pioneer and Onkyo because of the DTS/Dolby copyright.

I don't know how to extract the DSP data from the Pioneer firmware installation .mem files but the file I uploaded is tested and good. If your replacement DSP chip is working, the file should restore the audio.

i got a used VSX 53 as well, with no sound tried heat gun with flux and did not fix the issue ,guessing dsp needs replaced. can someone help if i send the board as i am not comfortable with Bga etc.
Thanks

Good news on your successful repair. You are lucky your Chinese chip works because they are mostly fakes. Did you buy the D revision or B revision one? Can you upload a photo of it?

I stopped buying them from Aliexpress and eBay because none of them worked and the markings on the chip had clearly been altered so there was no way to know which version you had bought.

Hello,

Here I leave the data:

It welded perfectly at 300º


This one really looks original, a while ago I bought another one for a vsx1021 that has the same problem and that one seemed like a bad copy to me, yesterday I tried to upload the 2021 file to the 1021 eeprom but it didn't work....it would be possible to extract from the file provided by pioneer.MEM the .BIN to load it into the eeprom???...

Luckily 2021 is working perfectly now...I'm very happy.

Sorry for the English, it's from the translator...

Re: pioneer vsx 2021 no sound

## Attached - DSP firmware dump from Pioneer VSX-LX55 ##

Tested and working in both VSX-LX55 and VSX-2021.

Circuit location is: IC9004, device is: MX25L1606E.

Version is 119 from Pioneer firmware AVR_1_204087119093

I loaded this into my VSX-2021 IC9004 although the rest of the receiver was still running an older firmware version. It then started up and ran fine. I was able to perform a full update via USB to the rest of latest version detailed above.

Hello, Thank you very much, same problem and solved by copying the.bin file to the eeprom. Before this I thought the problem was with the Chinese chip, but no... it's the corrupt software. Thank you!!!!

Thx so much for your work Andy! After flashing your file my VSX-2021 with a 'B' DSP and with the *** instead of DSP flash part# is producing sound again. Luckily, the MX eeprom could be flashed on-board with AsProgrammer. After switching on I checked the firmware number and was initially sad to see it was still showing ***, but after a few seconds it changed to 119. After toggling the source selector I immediately got UE22. After rebooting it a second time, there was no UE22 and there was sound via the VIDEO input. I still have to try HDMI inputs, but even if they cause UE22 I'm still happy I can use it with analog stereo sources. I should add that first off I heated the DSP IC9002 for about 40 seconds with a heat gun set to 270 degrees celcius ~1.5cm above the chip.

I still have a problem though... I can't find any firmware upgrades. It is currently on version 1-191-086-119-063.

Can anyone share the latest version with me?

If you want to try the file where I changed the version number let me know.

Sure. I'll try it.

Oh ok. I guess it's up to Andyb1712, I hope he logs in again.

Re: pioneer vsx 2021 no sound

I took it down again, If the revision number I changed doesn't work there is no point it leaving it up.

Re: pioneer vsx 2021 no sound

I changed it from 12_0242 to 12_0243, using hex editor, see it it works.
Does it display the current firmware? maybe that could be a clue what to change.
I did not want to leave the files up incase it did not work. I can upload the edited file if needed.

Where have you uploaded it? Can't seem to find it.

Re: pioneer vsx 2021 no sound

This is why links are n.f.g. they disappear. Have you tried changing the file name to a higher number, like avr_12_0243 ?
The other option might be to change revision and release numbers in the file itself

I tried renaming the file. Still says "NO NEED UPDATE", I'm thinking this is internal to the programming.

Not sure how to change the revision itself. Might need a hex editor? only thing is that's where my know-how ends.
