Google is your friend search it 😉
I am out now good luck with the „repair“ ✌️

Check your firmware versions and if you see the question marks, then mess with the DSP.

Sorry to say that but these is not fully true because these question marks on the read out information on these Onkyo Amp‘s came from dead DSP or corrupted FW inside the NAND or bad NAND ☝️
Not only from a dead DSP what many people guess 😉

You are correct.

In the firmware screen where it shows all of the versions, everything shows numbers except for "D" as it's just question marks. I think I'll take a shot and get my hands on a known working DSP (so it will have to likely be a "D" rev chip). I just need to know where I can get a real one. I've read that an individual on this forum named "TJMotter" does this by ripping them off of dead boards but I'd prefer to get my hands on just the part itself if possible. If the only solution is getting them off of dead boards, what model receiver boards should I look for and where could I find these boards? Nothing seems to be on ebay at the moment.

Your only chance is a board. Nobody is selling these chips separately, only manufacturers of receivers. I'm not sure which one, but if I remember correctly, Tj said that the TX-NR838 has the updated chip. It is hard to come by bad HDMI boards.

Would the place that I'd most likely find dead boards be on Ebay? I can't really find anything there. Is there any site that has a higher chance of finding what I need?

Why get my last post here deleted I wrote nothing wrong 😤
If is something not right send me a PM please ☝️
So I write it now exactly again what I wrote ☝️
Nobody with brain would scrap a high end Amp to fix a low end Amp.
The chances are also good that your NAND or FW in it is faulty and than the 616 is silent forever!
Even a working DSP would not fix the Amp than.

Your post is a repeat of what you have already posted multiple times in this thread and your belief that it is not worth fixing. This forum is not based off whether something is worth fixing or not, but for those wanting to learn the hobby at their own expense. I think he understands your opinion by now. And it is not an answer to his current questions. I want people that come here to be excited about learning how to fix stuff and not be discouraged by negative opinions. And please do not take this offensively. I would like to respect all members opinions. Just would prefer them to be limited. |

Hey Admin ✌️
nice so you deleted my post also wow I not suspect that…
Sad in my opinion and yeah that’s true I try to tell him that many times because it seems he not understand it well in my opinion…
That is my personal knowledge and experience with these amps and I share that also for free 😉
I got you in some point‘s but not agree in all 😉
I hate it also when not right stuff is try to tell in your words to hobbyist but that is than fine it seems here…
Maybe my not less knowledge in these Pioneer and Onkyo Amp‘s is not longer needed here on that RAA Forum and it were time to say good bye…

Would the place that I'd most likely find dead boards be on Ebay? I can't really find anything there. Is there any site that has a higher chance of finding what I need? I have so far never come across a list of receivers that have these DSP numbers but I have at various times seen these numbers when looking over schematics doing other repairs. And I believe I have seen these numbers in other makes of receivers besides Onkyos and possibly even the home theater in a box units. But I never made a list of any sorts so I cannot help you there. But it maybe a way for you to at least search for units that may have these DSP's. Just search various schematics to look for your numbers. |

These boards are scares, you have to check Ebay often, sometimes somebody sells quite many of them, sometimes there is nothing available.

Check the 2nd from last page in the tutorial thread. Not only do I outline what boards you can use for parts but I also describe the process for heating the chip. 300 degrees isn't going to get the job done. I typically start with 380 degrees but usually end up at 430. You are aiming for a heat cycle of about 1.5 to 2 minutes max so a pre-heater is a definite help.

Thanks for your response, Todd. I've heard something about how D revision chips that are sold are really just B rev chips pulled from dead boards sanded off and reprinted. So my question now would be is anyone selling actual D rev chips pulled from dead boards? I'm finding a hard time coming across a dead board with a D rev chip and I wouldn't want to mess with putting unnecessary heat cycles on it which would increase my chance of ruining the chip. Especially since I don't even know whether it is the DSP chip or the FW inide of it that's gone bad.

I have some genuine B and D Revision DSP‘s in stock 😎
We’re are you from?
But the problem is again your maybe also faulty FW inside the NAND or even worst a bad NAND…
