Let's fix another ONKYO with no sound!

[@eduardoavila646]

I really like that you don't stop on the "is it still worth fixing" and just do it. On other channels i usually end up stuck on: "what if they tried to fix it anyway?"

[@Tony359_2]

eheh thanks - I can't just let go :)

[@snakezdewiggle6084]

Yeah, makes me wonder if those others actually know how.! So many of them make dumb assumptions. I take every opportunity to learn, fix or fail.

[@peanutbutterjellyjam2179]

Funnily enough, my Onkyo TX NR 171 has the 'D' version chip, and it also suffers the no-sound issue. I had it re-balled some years ago, however, it has started acting up again. To get it going, I use a heat gun on it for a few minutes, and it works until it doesn't. Then another heat treatment and so the cycle goes.. Great video!

[@Tony359_2]

oh that's weird...

[@bpalpha]

I've seen people add heat sinks or even active fans to this DTS chip in order to keep it functioning. I had a TX-SR604 by Onkyo which worked great, but you could cook waffles on top of the unit if used for long periods.

[@Tony359_2]

Yes, Onkyo are space heaters. However it's not clear whether those DSPs fail because of temperature. One can only hope that it can't hurt to have a heatsink :)

[@ezeicom1]

Good Man thanks

[@kavinsiva1634]

please do more AVR repairs its very interesting

[@Tony359_2]

thanks! I have one which has been sitting on a shelf for years...

[@minombredepila1580]

Aliens talking to me..... Hilarious..... Very nice video, showing how manufacturers squeeze the electronics on that boards. I understand this for computers, but for HiFi, I wonder if there's some sort of interference between the "packed" circuits.....

[@Callum-Faulds]

Chances are that the A revision was built with lead based solder before the laws required the use of lead free. The B revision was made with lead free as it's from 2010. My best guess is that Texas Instruments didn't quite get the chemistry right when producing these are lead free has fundamentally different thermal properties as well as different contraction properties. As a result, the solder actually inside the IC is likely what failed on them all, causing these defects. I don't know about the C revision but the D revision presumably fixed those issues. Bumpgate, as it's called, was responsible for the YLOD on all but a few of the FAT PS3 consoles and most of the FAT Xbox 360 consoles also. There's a 1hr 30 video by Rip Felix here on KZbin which covers it all.

[@Tony359_2]

I’m familiar with bumpgate but I thought the issue was the compound they used to secure the die to the substrate. I don’t think this DSP uses this technology but do knows.

[@andrewcrawford2093]

Hello Tony ,you flew through the process a bit quick for me to understand I need the hdmi pcb for the onkyo 609 ..on the pcbway website do I need to give then the serial number of the pcb,coz when I asked them if they had a replacement hdmi pcb for an onkyo 609 they couldn't seem to help me.

[@Tony359_2]

Hi - you might have misunderstood me. PCBWay happens to manufacture PCBs but you cannot buy a replacement HDMI board from anybody. The one I got here was from Ebay, pulled from another 609. Sorry!

[@nigelparker5886]

Hi, good vid., I have same problem with a 609! May I ask how you sourced the pub from PCBWAY? Cheers

[@Tony359_2]

the Pub?

[@nigelparker5886]

@ Sorry, typo! PCB! Cheers

[@Tony359_2]

ahah! Which ones? :) The ones I show in the advert are mostly public projects - the ISA 90 degree extenders are my design and can be found on the PCBWay store but the gerber files can be downloaded for free. www.pcbway.com/project/member/?bmbno=D27E41F7-4CD4-49

[@nigelparker5886]

@ Thanks for your reply. I’m not that technical, but I was thinking that if I could obtain a later PCB, including the dodgy component chip, that I could swap out and rescue my TX NR 609!? Did you say it was around £40? Mine has a later repaired replacement component and strangely has lost picture but not the sound? I assume that this is still the bad hdmi board that’s responsible! Thanks for your time! Cheers

[@Tony359_2]

PCBWay make "empty" PCBs. What fails with the onkyo is the DSP IC which cannot be sourced. In short: PCBWay cannot help you, I'm afraid!

[@fireplays_official]

Hey, I don't know if you know what the cause could be to my problem but, We have a Onkyo TX-NR646 from 2016, and over the years, slowly it's started doing some weird things like when pressing one of the source buttons like "CD" makes it go to the AUX input first and when pressed a second time, only THEN it actually goes to CD. Or like the remote failing to work properly, as if its recalibration keeps lessening until only the volume buttons on the remote still work. And now I've heard you talk about a possible vulnerability of these chips, I wonder that DSP chip might be the issue to all of these strange issues, unless it's a firmware problem and I should update my receivers firmware?

[@Tony359_2]

I'm not sure I can help you but if the DSP fails, the onkyo stops outputting sound. I'm not aware of a different failing scenario.

[@darrenmurphy6251]

ive had onkyo (and others) hifi, dsp disco pa speakers, and bose amps from cars still fail to work after dsp ic replacement for silence, screetching, hiss or poping/cracking , always results in silence and had to assume theres firmware loaded up on those chips and the replacements are no doubt blank ,best guess i came up with anyway

[@snakezdewiggle6084]

G'day Tony.! My Onkyo killed all the right hand side speakers. 8 months out of Warranty. Centre and Sub have no output at all. Its a pity cos they have great gear.

[@Tony359_2]

Hello - it's weird, the LFE is not a powered output (unless it's one of those very low power "HT" series).

[@snakezdewiggle6084]

@Tony359_2 Hi Tony. Yes you are correct.! My mistake. It was a Sanyo Amp that burned the speakers. The Onkyo lost RF, RR, Center, Sub. I was so angry, I didn't even think of searching the Internet. I focused on rebuilding the speakers, coil, cone, etc. The Sanyo and Onkyo have banished to the cupboard awaiting repair.😠

[@Bergi2000]

❤

[@SidneyCritic]

I would keep it incase the new one needs that chip.

[@diogenescaruaru]

I experienced exactly the same path. Bought the chip from AliExpress and did not work, used serial monitor and had absolutely no output exactly like you. Eventually I found on eBay a new board and replaced and my receiver came back to life.

[@Tony359_2]

it's so sad that there is no other way...

[@danielyazbek9910]

I always wanted an onkyo receiver, but here in Brazil they are VEEERYYY expensive 😢

[@norbertsmallegange6331]

Don't, ! Everything what onkyo is Advertising is the opposite way! The advertis a very Bright fm tuner , no its not The advertised All kind of qualities in the sound and i found out it is not! I had a few tuner receivers, pioneer, akai, denon, grundig, onkyo, jvc Onkyo was the worst.

[@danielyazbek9910]

@norbertsmallegange6331 I had an Akai AA-A35, I think was from 80's, was incredible, now i have nothing 😓

[@bitsundbolts]

The story about those TI chips is very sad - and the fact that supply is short and will run out some day.

[@Tony359_2]

the saddest part is that... there is NO supply. There has never been. Because those ICs contain proprietary codecs....

[@rimmersbryggeri]

Can you not download the firmware through the serial console?

[@Tony359_2]

I'm sure there must be a way, do you know how to do that via console?

[@rimmersbryggeri]

@@Tony359_2 No I have no experience in that at all. IT just seems like somthing that should be possible. For someone who is good at linux.

[@eduardoavila646]

​@@Tony359_2 Is it possible to send commands through this terminal? I think it could be possible to send a DD comand to basically image the whole filesystem and with the output to the very own serial terminal, then on the pc acessing it, you would need to output the data directly into a disk image like an .img. No idea if this is possible, but if it runs linux, it may have these commands

[@Tony359_2]

@@eduardoavila646 I know some commands can be sent but given the small NAND I wouldn't expect many commands available. To be honest I think the best option would be to de-soldered the NAND and image it. I also understand that some of those ICs are encrypted, so not a piece of cake apparently.

[@309electronics5]

​​@@Tony359_2Often (but not always) Uboot (the bootloader that initialises the chip and loads the Linux kernel and initrd) has a few commands that allow dumping the filesystem/firmware to external media or even over the serial console (although that would take a few hours probably because serial is slow). If you can get into the shell by pressing any key during the "press any key to stop autoboot" prompt you can run some bootloader commands but sometimes they set the bootdrlay variable to -1 meaning it will skip the check but maybe you are lucky

[@blackIce504]

Thanks again just to let you know for some reason i had to resub....

[@Tony359_2]

Welcome again :)

[@Sulphur_67]

we need someone to reverse negineer the chip and remake it eith an open source hardware thing

[@Tony359_2]

It’s impossible unfortunately (I think): it contains proprietary codecs. I guess someone could design an ARM DSP with free codecs but I’m not sure it would be useful…

[@jasejj]

This was a bit of a tragic story in the end. Onkyo, a very old and highly respected manufacturer, was ultimately ruined by this fiasco, despite having no control over the quality of these chips, and standing by its customers long after the guarantee expired. The reliability of these other than that chip was excellent. Meanwhile the company with the quality control issues continues with its reputation completely unscathed.

[@Tony359_2]

ah yes, TI seems to be unaffected! :)

[@dfloper]

Actually reballing does not fix anything with the chip. It my work for a few months because the actual damage is internal.

[@Tony359_2]

Yes, I made that very clear in both videos 🙂
