Onkyo TX-NR609 New DSP chip fitted

[dkneyle]

Just thought I'd relay my experience here in the Land of Oz with this well-known Onkyo DSP fault. My receiver is actually the TX-NR509. Service agent here is AmberTech. Great service when talking through the issue with their service tech. I was told they request a replacement board from Onkyo and re-fit it. However when the repair came back it failed again almost immediately. A look at the replacement board indicated it was a re-worked board; could see the flux stain around the DSP chip. No argument when I contacted AmberTech; back it went again. Came back with an obviously new board and fingers-crossed, seems to be working fine.
Remember people, this repair program concludes at the end of 2018. If you are having issues don't waste time.

I thought, that the end was 2017. They have extended it?

I think we need to add in a new step when teaching kids fault-finding techniques. "Step 0: Google the model number and brief description of fault."
My receiver had been acting bizarrely for a few months, sound drop outs, then nothing coming out. I kept blaming the kids in the house who love rearranging the rats' nest of cables at the rear of the receiver to use their gaming devices. Eventually when I convinced myself the receiver was at fault I decided to open it up and have a look. Of course, all looked pristine and extremely high-tech. It was then I remembered 'Step 0 of Fault Finding'. And all the references to this DSP fault referred to the repair program running until end of 2018. And certainly the service agent here in Australia honoured that.

Do you mean, checking online for the recall, before you open the receiver.

Yes, even before removing any covers, Google-search first. In this case, once I realised there was a recall program in place, I did nothing further; someone else's problem now to fix it.

I mainly try to repair TVs as a hobby (as you'll see from my other posts). So even with TVs, don't remove any rear panels until searching if there is a known common fault.

Got a strange problem with your car? Google-search it. I had a local mechanic going mad trying to find why my 4x4 had lost all power. After about two weeks (and he is a good guy; not a rip off merchant) he said he was stumped. Manufacturer offered no useful guidance to him. So I Google searched the problem. Answer: 'Replace the catalytic converter'. His response: "That couldn't possibly be the cause of complete loss of engine power, but if you are prepared to pay for it, I'll do it." You can guess where this is going? To use the Aussie vernacular, he said "Well, bugger me!" when it solved the problem. It wasn't logical, can't be explained why it was the cause and the solution, but people had reported it on the interweb and therefore Google found it.

I actually had an issue like that, with my old Mazda MX6-V6. It was barely rolling.

My receiver has no serial number, It looks like it was peeled off, probably a big red flag as to not having it repaired for free? DSP issues? No net (grayed out) no USB init, I do get DIRECT sound (only) from FM, and I do get audio/video as well as pass through via front HDMI port. No speaker icons.

can you access via JTAG without chip in place/functional? I have both DSP and HDMI chips off board and need to find if the onboard firmware is corrupt. USB and upgrade were grayed out when chips were onboard as well as speaker matrix display.
