25 months ago, I bought a Onkyo TX-NR809 Home Theatre receiver.
http://www.audioholics.com/av-receiver-reviews/onkyo-tx-nr809-fl

It has been a pleasure to use, until recently. It started to have audio issues & finally stopped working with no sound & some options greyed out in it's set-up menu.

Long story short: Some, correction, a lot of the models that had been built in 2010/11 have developed the same fault as mine.
Evidently, there is a component on it's HDMI board that is failing after many months of use. I spent a day searching the Internet about it and forums have pages & pages of disgruntled customers, with the same fault

Onkyo has stepped up and is repairing them, no questions asked.

Any other Onkyo owners having/had the HDMI board problem?

I sent mine off to the importer/distributor. I had bought it from them. Was told a 2/3 week turn around.
I was pulling out the banana speaker plugs, that had been soldered onto my monster cable for the past 23 years when one was being difficult to get out. I pulled some more & felt something 'give'. The banana plug would not come all the way out and the speaker terminal pulled away from the back of the chassis by a few millimetres. Oh Hell
.
It went off to Auckland with the banana plug still in the socket.

I have asked for the person doing the warranty repair to the HDMI board, to have a look at what I have done and give me a quote for repair.
Hopefully, the two side arms that attach the terminal to the chassis, look like they have pulled out a bit & I can wiggle the terminal a bit sideways. I have my fingers crossed that all it will take is to re secure the arms inside & solder back onto the internal board, if needed. I took the cover off the chassis but the speaker board is hidden at the bottom, under two other boards that obscure it from view.

I have just fitted all new banana plugs to the 6.1 speaker wires.
To say I am pissed off with myself, is an understatement.

The hourly rate these electronic shop charge...................... :(

were these regular bananas or some form of locking banana plug (eg. monster x-terminator) ?

i've never had a banana plug get stuck but have had locking wbt bananas that wouldn't unlock and thise stupid monster 'turbine' rca's that ripped out an rca socket.

They weren't locking ones. Carl, who worked at Sound Expression Wellington, crimped them onto the regular looking (although rather expensive I thought) plugs when I bought the monster cable 23 years ago. I later flowed solder into the crimp. As an afterthought, I could have sprayed CRC onto the plug to get it to unjam, but the damage had been done by then.

My workmate and I bought NR-708s at runout prices from JB HiFi roughly 3 years ago. We knew about the HDMI problems before we bought. Mine failed after 9 months - sent off and sorted under warranty, fine since. Workmates died a couple months ago - he took it into JB, said realised not under warranty but known issue and that Avalon (importers) should be sorting it out for free, and they took care of it. Thankfully no binding post dramas here!

So many parallels to my thread lower down the page except I got the 709 and mine went for 28 months before the HDMI died... JB in Wellington said they would sort it no problems (off to Avalon..)

How long have they had it? Mine was sent off a week ago and they reckon 5 week turn around frown

It sure sounds like these are not well made :( binding posts should be sturdily mounted to the chassis, not relying on solder joints...

Workmate and myself both had roughly 2- 3 week turnaround. Thats from Palmy.

Avalon said that the person they send the Onkyo too, collects them on a Wednesday & returns them on a Wednesday, to Avalon. I was told 2 to 3 weeks for the HDMI repair. It was at Avalon on Monday the 28th April & I assume it went out for repair on Wednesday the 30th, which is a week ago.

Have been waiting for contact from either Avalon or the repair tech, as I said I wanted to be contacted before they went ahead with the speaker terminal repair. Not interested in paying for a new speaker board as, at the most if I have damaged the board, soldering jumper wires over a cracked track is much cheaper. lol

I'll go along with that. You shouldn't be able to pull a binding post off the chassis. Certainly not by trying to pull out a banana plug, which IMO is the worst type of speaker connector after spring loaded clips.

O/T but what would you consider a good connector then? I've always had good experience with banana plugs (never pulled out a binding post luckily!)

Notified today that receiver has been repaired and will be sent out today, after I pay for the binding post repair. That cost $76. Count myself lucky I did not do a pile of damage. I have asked what was replaced on the HDMI board but have not had a reply as yet.

Put the wire throught the hole in the binding post and screw up tight. Don't plug banana plugs in the end as connection can be erratic if plugs get sloppy.

I think they replace the entire hdmi board on my Onkyo. I'm assuming it just plugs into the system board though.

Mine arrive Friday morning. I had a look inside and a new HDMI board had been fitted. The paperwork that came with it said "confirmed dsp f/w corrupted - new dsp pcb required. Fitted new pcb".

If it is the original design board that is fitted, then there is the chance that it will fail again in another couple of years. If it does, under the Consumer Guarantees Act, if a repair fails then it is the consumers choice for a repair, replacement or refund. Been there done that so know that is true. The time factor would make that more difficult but, with all the information out there about this board failure that makes it obvious that if you put in a new, unmodified board that has the likelihood of failing again, then I believe one would prevail, under the Act.

Re the speaker terminal: my fault apparently. Nothing was said on the paperwork but returned with the receiver, was a bag containing the banana plug and what is part of another banana plug, which I recognised as a type I have used in the past. I can only assume that I had, at some stage plugged in a el-cheapo banana plug & when I removed it, one side of it had remained inside the terminal.

It would have been the side away from me as I would have noticed as I looked at the plug coming out. The replacement plug went in smoothly but jammed coming out two years down the track.

Fitted all new ones this time around. A pair of new binding posts had been fitted. There is a screw directly above the pair so I assume that holds them in. Don't know why the post had come out a couple of mm.

All up and running again, sounding as sweet as ever, except the pesky sub. That always booms when I listen to Internet radio but integrates sweetly with any other source.

Sounds familiar to what mine said. My understanding of the fault is part of the manuafacturing process for specifically the HDMI boards, they dip the boards in some sort of acid wash finish and on this particular model there was something wrong with the mix (too strong or residue not properly removed afterwards) which ended up eatling away at the PCB till finally it failed after an indeterminate period of time. The replacement boards have not been subjected to the same incorrect process so should not have the same issue. YMMV and Murphys law applies obviously.  cool
