post #5431 of 5476
so in case of a botched firmware upgrade, or even potentially a blown PSU, a system update will resolve this...let me ask you this; if your doing a BIOS update on a PC, and you fudge it up to the point where your PC will not power own, do you do a system reset? Or replace the bad unit?
post #5432 of 5476
Ron - I think I originally took your question opposite of what you meant. I read it as "Why won't a system update turn it back on?". Now I read it as what I believe to be your intent, as a comment to anadigi's comment to just try a System Reset.

But to answer your question, You botch your BIOS update, you need a new BIOS chip
post #5433 of 5476
indeed, I think with the unit being on its side, whilst doing a firmware update, whilst being knocked over and losing power may have had catastrophic results...ie...may need a new power board and logic board in the unit.

I finally heard back from Onkyo (Michael Russo is no longer with them in case anyone tries to email him directly). I'm getting another out of warranty fix, which is nice. Had hoped for a replacement unit, but I'm hoping the newer fix is better than my original one. Last time they had me send it to United Radio, which it started failing just 4 days after returned. This time I'm to send it to Alltech Electronics, also in NJ. United Radio did not replace the hdmi board, I'm thinking they re flowed the dts chip only....here's hoping they have the magic fix and a new board this time. I'll have my fan and thermal switch ready, so hoping keeping it cool will make it last another year-18 months....

Thanks I hope so too! Did they tell you they were replacing it in your prior communication, or was it not until you sent it in for repair? If nothing else, I'm impressed they're still helping me out. I know some have just tossed them swearing to never buy Onkyo again, but I have to say I've been pretty happy with customer service so far which is rare nowadays.smile.gif
post #5437 of 5476
after a month of me calling them back and asking for a status, they said they are replacing the unit.
post #5438 of 5476
Cool thanks for the info, knowing that I'll make sure I stay on top of them smile.gif

My beloved Onkyo 807 has just started to display the pic but no sound symptoms. Same as described no speaker detection. After I let the unit warm up for 25 mins and turn it off then on again it starts to work. I don't think this will last long. Really pissed off I spent $2,000 (Australian) on this amp and got 3 years 5 months out of it. In fact its already been in the shop for repairs for a blown channel which took 7 weeks to fix. I have contacted Onkyo Australian support but have a feeling since its out of warranty by 5 months they won't help me.

 

Any recommendations on a replacement amp?

berzo84 - Keep the faith. Given all of the other owners in this thread who have had Onkyo step up and take ownership of the issues with the 807, I would say your chances are very good. My guess would be that it doesn't matter if it's US or Austrailian support, Onkyo knows about the issues and should probably help out. I would reference the fact that you have read about many other owners having theirs fixed out of warranty for the issues that plagued the unit. Good Luck and let us know how it goes.
post #5441 of 5476
Yes, don't give up hope just yet. I'm well past 5 months out of warranty and was just granted a second out of warranty fix, shipped the unit off today. Good luck!

Not really true.

Debugger inputs on processors allow you to execute arbitrary commands without having to access memory. You can bootstrap the cpu and rewrite the firmware with moderate difficulty through debugger inputs. "JTAG" is the acronym you will hear the most. Stands for Joint Test Action Group and usually refers to a standards compliant interface, but there are plenty of other debugger interfaces out there.

So, for example, satellite tv providers now require receiver boxes to be built with the debugger contacts actually hidden under the cpu and not connected to anything, because smart people learn now to reprogram them.

There are, what, a half a dozen little slots in the back of this receiver with sockets for printed ribbon cables.

I'd be astonished if there isn't someone in japan who knows exactly how to write the firmware without even taking out a screw. Probably has the cable in their desk drawer.

However it would not surprise me to learn that this knowledge and/or equipment never trickled down to the service centers.

Same here. Way out of warranty but Onkyo authorized a SECOND HDMI fix. Seems like there is a right way and a wrong way. Best Buy fixed it the first time and it only lasted about 50 hours before
I had a problem. Another company fixed my 3007 a year-and-a-half ago and it's been fine for about 500 hours.

Hello!

Since the purchase I have already made paid 2 replacements of sound board at my TX-NR807 in official service point at Moscow, Russian Federation.
On my request to replace the flawed unit Onkyo refered to local distributor in Russia, which, in turn, refused to replace and offered paid repair.

Is there any way to replace the board manually without service point?

Thank you!
post #5445 of 5476
any board can be replaced, but the cost can be high for the said board.

Hello,

I have an 807 for 3 years with no problems with klipsch synergy f10 speakers. I want to move on and I read about sony str-dn1040 but i dont have where to listen it. I want also to upgrade my speakers this year to klipsch reference or dali zensor. The new Avr needs to be futureproof with 4k and everything for the next 4 years. Is this a good choise, or not as good to power and sound compare to my 807. I dont really care about bells and whistles like spotify, zone 2, etc, all I want is best best sound for music and movies at a acceptable price. Can you help me with other suggestions? Thanks you
post #5448 of 5476
I would try asking in the sony receiver forum, not this one.
post #5449 of 5476

Thank you,

Because I love Onkyo I tried here first :) Maybe somenone will recomend me a GOOD Onkyo, meaning trouble free. After I constantly read this thread, every day I fear about my 3 years and 1/2 807. Ant help will be apreciated. Thank you.

are you having issue with the onlyo?

If you're not having issues with it after three and a half years, then it will probably not have any issues beyond normal wear and tear all electronics get. I've had mine for the same amount of time and it hasn't had any problems.

You can find any receiver can have trouble if you look through the other threads about them, because people don't usually post that they're having no trouble. They post because their item had a problem and they want it fixed, so yeah, of course you're going to find horror stories here. There is no one perfect trouble free receiver model. Put your fears aside and enjoy yours.

Nope. Not a single one

No...

I've had this receiver for several years now, and had the HDMI board replaced due to sound issues.

But now, when switching between inputs, I get no picture on my screen. The only way to get it back is to turn-off the receiver and turn it back on. If I am in an input, and am getting video, pressing the setup on the receiver's remote does work... so I don't think there's a problem with my HDMI cables in total, but some kind of "handshake" issue is going on. Any ideas on what can be done to resolve this?

HI, i have a request to persons who had HDMI boards replaced in their units. Can you please take a photo or at least read markings from DSP processor (Q3001) and post it on the forum? I'm curious if Onkyo placed a newer revision of the chip on the HDMI boards they mount. If the chips are same there is highly probable that the units will fail again after 2-3years (assuming the chips are new).

Welcome slaw82...

I had the HDMI board in my 3007 replaced about 1-1/2 years ago, it recently failed again, the chip on the failed board is from TI, and I suspect that it is not at fault but rather an error in design where that chip is being powered by too high a supply voltage, eventually this blows the chip. Late in 2012 Onkyo released a service bulletin that discussed this and supplied a daughter board that reduced the supply voltage from 3.2 to 3.1v, also soon after the replacement boards for the 3007 came with this modification already in place.

I am not sure if this is the same issue with the 807 family of AV receivers, but I am sure there are strong family design tendencies within the HDMI implementation. Below is the Q3001 chip on the 'old style' HDMI board in my 3007.

This picture is yours or from internet? On picture DSP is D830K013 and NR3007 service manual says that the IC should be D830K011. Failures of the units are not Onkyos fault, TI is the one to blame. I have official TI bullettin which says that huge family of DSP processors manufactured by them has design flaw and it's the reason of premature aging of the chip. TI made corrected version of the ICs and they are on the market from 2nd quarter of 2013, they have markings D830K13 (or K11) DZKB instead of AZKB and BZKB on the previous versions. Unfortunately i can't find them to buy anywhere :/

This is from my 3007 that I just shipped off for repair, the picture was taken yesterday. I don't have a picture from the original HDMI board that came in the unit. At any rate this HDMI board was installed in May of 2012 well in advance of newer design chip being available from TI.

As I said Onkyo did release a service bulletin to their authorized depots about the voltage issue, here is the post http://www.avsforum.com/t/1170804/onkyo-tx-nr807-official-thread/5220#post_22225196

I've replaced my board twice, the first time Onkyo complained about it as it was 2-3 months "Out of Warranty" .....the second time I had purchased a protection plan from DirecTV and they replaced it......I still have the DTV protection plan on everything with a screen (i.e. includes amps and projectors)
