Onkyo NR609 usual Dolby/DTS DSP failure

[tony359]

Hi all,

I have a TX-NR609 which shows the usual issue with the DSP on the HDMI board.

How do I know? I managed to revive it with heat. Then it failed again. I reballed it, it lasted 3 months then failed again for good.

I ordered one from China - not knowing that
1. It's likely fake
2. It's likely pulled from another broken machine
3. There is a revised version which does not fail, which was never sold outside of OEMs so unlikely to be found online

I installed it and it didn't work.

The bottom line is that I have this nice amplifier which works besides that IC. I don't want to throw it away but I don't know where to find the replacement IC or board. I could try China again - and maybe this time not wait 6 months before installing it so I could ask for a refund?

I read a thread on a forum where someone with great experience on the subject said that the only way is to find a replacement HDMI board with the latest DSP version on it. I am unable to find it.

Any ideas? I'd hate to throw it away even though it's not worth much.

Thanks!
Tony

Try flashing nand with firmware dump... it's sometimes broken

Re: Onkyo NR609 usual Dolby/DTS DSP failure

oh yes, I was supposed to try that - do you know where I could find the firmware?

I believe on another forum there was a note about connecting via serial and see if the IC is trying to boot

Re: Onkyo NR609 usual Dolby/DTS DSP failure

the dsp from china was probably blank if it was new.
programmable parts get programmed AFTER soldering - more reliable that way!

[tony359]

Re: Onkyo NR609 usual Dolby/DTS DSP failure

Maybe. But I am also told that those ICs were never sold outside of OEMs so all China ones are fake/broken. And if not mistaken the EEPROM is on the PCB? The DSP is more or less a CPU which boots from the ROM. But I might be saying rubbish here.

Still, I can try to give it a go. Do you happen to have a pointer on where to find more info about that?

Meanwhile, I have another Onkyo I THOUGHT was working but no, never passes audio when cold, needs 5 minutes and a power cycle to work.

Sigh, another useless heavy brick. This is a powerful one, 250W per channel.

Re: Onkyo NR609 usual Dolby/DTS DSP failure

do you have the dsp part number?
remember everything is made in china - they have access to a lot of parts

[tony359]

Re: Onkyo NR609 usual Dolby/DTS DSP failure

D830K013BZKB300

The other one I have has a different variant, D830K011A which likely means is even earlier than the B.

Apparently the "D" version is the good one which does not fail. Sigh!

Good point about those parts being manufactured in China, who knows someone might have found a tray forgotten somewhere.

I'd like to try to access the serial port of the 3007 - the bit 250W I realised today that also failed. I mean the DSP serial port - it's an ARM processor apparently.

I think I'mm wasting my time though.

Edit: apparently the recall was for revisions B and C, not for A. But expert TJmotter said those ICs fail around 18K hours and my 3007 has 19K hours. Still, it behaves differently. It always powers up ok after a few minutes, it just needs a power cycle, so maybe I'll check the supply - and the serial port.

The bottom line is: I have two of these bricks which I'd like not to throw away or harvest for parts. I really hate thinking they work, they just need ONE IC but it's unobtainable...

Re: Onkyo NR609 usual Dolby/DTS DSP failure

i see they didnt label the SWIM interface - no surprise there.
they dont want anybody connecting a serial jtag adapter to it and reading the silicon i.d.

[tony359]

Re: Onkyo NR609 usual Dolby/DTS DSP failure

there are other pages about that IC, maybe it's somewhere else?

[stj]

Re: Onkyo NR609 usual Dolby/DTS DSP failure

maybe
it's probably not a custom part, but it's got a custom number printed on it.

[tony359]

Re: Onkyo NR609 usual Dolby/DTS DSP failure

now I've realised that my own Onkyo pre-amp I use in my Home Theatre has the same DSP! It's got a heatsink on it but it's a ticking bomb!

I can't believe there is no reliable source of those ICs to fix those AVRs. So much working parts that can't be re-used because of one IC!

Re: Onkyo NR609 usual Dolby/DTS DSP failure

out of curiosity I managed to connect to the IC via RS232.

If I spray it with cold gas it fails to boot or hangs during boot.
What's weird is that it just needs 60 seconds to warm up, then it ALWAYS boot.

My previous cases were more digital: either they'd work or they'd not.

All I can do is to reball it (it's an A revision which in theory is not in the list of affected chips) but I don't think it's the problem as it really takes a tiny amount of gas to stop it and if I mechanically tinker with it I don't see any effects.

Re: Onkyo NR609 usual Dolby/DTS DSP failure

I didn't know people go through the effort of reballing! Since I don't have the tools or skill, I've just been doing the heatgun trick. I shield the chip surroundings with some tinfoil and blast the heatgun until I measure 200C on the chip. I then let it cool slowly and naturally, then stick on a heatsink to the chip. I also modified the onboard fan to run all the time (there's a spare connector somewhere that puts out a constant 12V). Has seemed to holdup for the last year so far.

I've also done this to fix a Toshiba plasma TV and it's held up for >4 years so far. So maybe the trick is to keep the chip from too many extreme thermal stresses by having a fan over it.

Re: Onkyo NR609 usual Dolby/DTS DSP failure

@nobbnobb1

The issue with this IC was acknowledged by TI, the manufacturer. Heating it up only fixes it temporarily. There is a newer revision available which should not fail but it was never made available to the public.

[tony359]

I forgot I discussed my issue with the Onkyo 3007 on this forum.

I made a video "repair" of this unit where I try to explain what happens from all the info I got from various sources - which are all mentioned of course

I post it here for future reference - it's so sad that those beasts cannot be recovered because of one tiny IC...

[tony359]

I was forwarded the Texas Instruments bulletin which confirms that only B and C DSP ICs were deemed as faulty - the "A" you see in the 3007 video above is likely to have a long life after the reball! Fingers crossed!
I cannot find this bulletin online anymore so I thought I'd share it here.

You should have checked here https://www.badcaps.net/forum/troubl...50#post1131150 post#40
By the way, nice video, it will be interesting to know what will happen to the IC.
