Re: Arcam AVR400 No sound
Managed to find the fault. It's the Codec IC that's faulty.
Receiver is getting power now.
Would have loved to get a replacement VFD, but this seems like a dead-end.
I'm actually loving the sound this receiver gives, pretty clear mids and highs.
Bass could be improved but overall pretty nice sounding receiver.

Re: Pioneer Elite VSX-52 DSP EEPROM
I'll looking at it tomorrow. I believe it worked before.. I got this receiver already with no sound.
Spent hours researching online until I saw Andyb's post about his LX2021 and his EEPROM. The post also mentioned about VSX52 so I thought I should try burning it directly to the EEPROM with my CH341a. I was actually surprise I got sound. But then this FM issue. Well at least I got sound....Leave a comment:

Re: Pioneer Elite VSX-52 DSP EEPROM
I removed the tuner module, and true enough no more crazy tune to all frequency issue. Could this be the tuner? Or just the programming that's messed up?...Leave a comment:

Re: Pioneer Elite VSX-52 DSP EEPROM
BD3473KS2 IC2501 . It is supposed to be the volume IC. Preamp / Selector.
Unfortunately, I didn't have the programmer back then when I updated the firmware from USB. So I don't have the backup.
Also, I can't get to the module without disassembling everything. There are 3 PCBs stock on top of the other.
I did try to remove the FM module to see if it the problem is removed with the module disconnected and was clumsy enough to turn on power with some cables disconnected. Now the receiver has...Leave a comment:

Re: Pioneer Elite VSX-52 DSP EEPROM
It's amazing though that it keeps on updating even with the same file in the usb. You should leave the file up. As it works as intended. Now I'm thinking there is really something wrong with FM and AM being tuned in all the time. CD, DVD and other inputs work. Just the tuners are out with no sound.
Oh, before this I had to replace the mux IC as it was popping when I turn the volume up or down. That solved the problem, but spun out a new issue..the FM AM.one.. not sure if its worth mentioning bought the mux IC from ali, as it was...Leave a comment:

Re: Pioneer Elite VSX-52 DSP EEPROM
Amazing. AM is the same. Says tuned to any frequency and doesn't give out audio....Leave a comment:

Re: Pioneer Elite VSX-52 DSP EEPROM
Well.. shame.. FM issue is still there. Firmware at 1-204087119093. Makes me think this is really a problem with the FM module?Leave a comment:

Re: Pioneer Elite VSX-52 DSP EEPROM
Well what do you know.. I used the USB method to update it and now it's at 50% and updating. I hope this works.
Also, I thought I was going to use a programmer for this? Just the USB update works? Kind of baffled. Anyway it's still updating will update if this fixes the FM issue....Leave a comment:

Pioneer Elite VSX-52 DSP EEPROM
Alright had to make a thread for this receive as I felt like the other one was not really for this specific model.
Would highly appreciate it if anyone has the bin dump for this EEPROM on this specific model number.
The circuit is Location: IC9004 and Make is: MX25L1606E.
The IC is quite easy to get to as it is on the top side of the pcb, popping the cover off and it's there for the world to see.
I flashed the IC with another Pioneer model and I got sound, only thing is that FM is now all out and funky. Basically tunes in to every single frequency... -

Re: pioneer vsx 2021 no sound
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....Leave a comment:

Re: pioneer vsx 2021 no sound
Hi R_J, thank you for this. I tried updating the receiver using this file. It just keeps saying "NO NEED UPDATE".
This is the reason I wanted I asked a copy of @AndyB1712 's file and what he says in his post #36 link below. Wherein I think he tweaked the firmware and this fools the receiver into thinking this is a new update.

He provided a dropbox link, but that link now is dead. So I'm hoping he uploads...Leave a comment:

Re: pioneer vsx 2021 no sound
Hi Andy, not sure if you are still here, the link no longer works. Would appreciate if you could provide a new upload link?
I have a VSX-52 with the no sound issue, I flashed the EEPROM with the bin you have provided in post #29, and it fixed the no sound issue.
Only thing is that the FM doesn't work or there is no sound and the "tuned" display stays lit all the time. Even if it's not tuned to a any FM frequency station.
If I force it to tune to a known FM station in my locality no sound comes...Last edited by nodols; 01-28-2023, 11:40 PM.Leave a comment:
