Folks-


I recently obtained a TX-NR3007 that i believe was having the same common loss of sound issue most folks are discussing on this thread: http://www.avsforum.com/t/1192172/the-onkyo-tx-nr3007-tx-nr5007-common-questions-issues-hints-answers-thread


Summary:

The receiver was exhibiting what i believe was this common problem. It was no longer under warrantee. I reflowed the two BGA chips on the hdmi board, and it now appears to be working.


Symptoms:

Lack of audio

Communication issues requesting firmware version from DSP controllers

Communication issues with using ethernet port

Communication issues with using USB port


Fix:

Reflow of BGA Chips


Assurance it doesn't happen again:

Insure proper cooling to unit (plenty of clearance around cooling intakes and outlets)

Possibly heatsink the two chips



Followup:

Interested in results from others willing to/interested in doing this.

Interested in folks willing to donate their broken receiver for me to diagnose/try to fix (I would pay shipping)

More details as they become available at http://www.c-j-l.net/Home/audio/onkyo_tx-nr3007



The Full Story:

The initial symptoms for this amplifier reported by the old owner was a lack of audio.

Upon further investigation I found that it could not communicate properly with the DSP units or ethernet; When requesting to see firmware version, it would only display '??????-?????' or similar (all question marks) for DSP1/ETH, DSP2, and DSP3. (To do this, with unit on press and hold display, press the standby button, and immediately use the arrows next to the display button) This indicated to me that there is a communication issue on-board.

Futher troubleshooting showed that it would not pick up an IP address via network (under hardware setup, network did not even exit), and when a USB memory stick was inserted and source changed to USB, the stick was never queried (LED on stick never lit).


I decided this really seemed to be a communication issue.


Looking at the internals of the unit, the HDMI board which most service centers replace as a fix for the problem is the digital mainboard containing what seems to be most of the processing units. This would explain the 600+ dollar cost that has been reported if not under warrantee, i believe.


Two of the chips on the board were in BGA ( http://en.wikipedia.org/wiki/Ball_grid_array ) form factor- which with poor cooling has been noted to cause problems in northbridge and video chipsets in laptops as well as the famous red halo of death in xbox 360s.


Using some suggestions and timing from http://www.youtube.com/watch?v=vR8L3B3eDr0 , I re-flowed the two chips on the board that were BGA.


The amplifier appears to be working properly now (can play music from USB, check for firmware upgrades on the network, i can see the firmware versions of all chips, etc), although i haven't done thorough diagnostics on it. I am waiting to get the remote from the original owner.


I will post more information and pictures as i have a chance to update them here:
http://www.c-j-l.net/Home/audio/onkyo_tx-nr3007


If your amplifier is exhibiting these types of symptoms and you'd like to donate it for me to try to fix and report results, i'd be happy to pay shipping slow-boat to where i live in Oregon. Please PM me.


[Edit/Addendum]

I re-flowed a second board and was a bit too hot on it. Melted the front HDMI cable input and the power inputs. If using the heat gun method, keep an eye on these plastics. Board still worked, which was good- but could not use front HDMI input.


If you don't have a heat gun, or want a way that is more regulated, you could try the method described here by oscarav098 in an oven:
http://www.avsforum.com/t/1192172/the-onkyo-tx-nr3007-tx-nr5007-common-questions-issues-hints-answers-thread/4620#post_22813395


(synopsis:

Procedure:

- Cover HDMI board with aluminum foil with the exception of the BGA chips. There are a total of two BGA chips on the HDMI board for the 3008 receiver. You can identify these chips by the lack of visible pins.

- Warm up oven to 300 degrees F and place hdmi board on cookie sheet and insert in oven. Bake at this temp for 2-3 min.

- Raise temp to 385 and bake at this temp for 8-9 min.

- Turn oven off and open door. Let board sit for 30 min. Do not touch.

- Remove from oven. Remove foil and re install.

- Enjoy you newly working receiver. )

If I had one that were doing that I think I'd buy an HDMI board and install it. They can be bought for under $100.

Is that a used or new price?

You're not wrong there; That makes the most sense if you don't want to spend time on this or find out if this is the issue.

However- if the problem is systemic, how long will it be before the new (or used) board fails?

That said; if someone goes ahead and replaces the hdmi board, i'd be happy to pay for shipping to me of the faulty board to try this fix as well.



take care

Since you've got a 3007 the question is your's to answer - is it worth plowing $100 into this unit to fix it? My answer (to me) was yes - it'd be worth it to me to spend the $100 to get it working. And I'd stick a nice sized fan on it to keep the HDMI board from frying again. That is the problem with the Onkyo HDMI boards - heat. And Onkyo knew this and cheaped out - deciding instead to take the hit on warranty work rather than spend a few bucks on proper heat sinks and a fan to carry the heat away. I just got my Integra processor back from getting the HDMI board replaced - along with the am/fm radio board - under warranty. If it weren't under warranty I'd put $100 into it to get it fixed - then sell it.

Am currently having issues with my tx nr3007 similar to what's previously been discussed. Says "now initializing" constantly when attempting to use net/usb function. Firmware update and remote options are gray and can't be accessed. Audio loss however is intermittant at this time. Is there any way to reload via tftp or use bootloader to reset software? I've been told by onkyo it's a software issue. Are these the the conditions you repaired by reflowing the bga chips and is it still working?

I think im having the same issue on my 3008. When i first turn my unit on everything powers up like normal but no sound there is picture and everything else is good all the speakers show up on the display and the PL2 Movie DSX like its supposed to but no sound then i click it off and back on after 5 mins of being on and it works? IS that the same isse others are having?



If so where do you find the hdmi boards to by im having the same issues on my 3008? and someone can have my old board since it still somewhat works.


Thanks in advance

Soooooo... Since my 3008 now has no sound and I have 2 weeks left on my warranty, once it's fixed and I sell it what should I buy? Is this problem fixed in the 3010? I hate to give Onkyo my money after my current pos from them, but I did like it.

@leighton

There is a guy on ebay selling the reflow service, i blieve, including the addition of the lower voltage regulator.


Do a search for tx-nr3007 on ebay


Not sure about source purchasing a new or used board.


If you find out a way around, i'd love to have your old hdmi board




@mechris

No Idea, although the note in the repair guide listed in this thread says all boards manufactured post september 2012 have the fixed voltage regulator...

Tried oven and heat gun reflow methods and audio loss problem is gone so far. Have'nt heard obsessive relay clicking since either. Still don't have remote, netwok, and firmware menu options (their grayed out) both procedures are simple and relatively safe (if you don't over do the heat gun like me and pop capacitors). Would recommend this for anyone out of warranty. Atleast the audio is back.

You could always trade it in towards a newer refurb if all else fails:D

Don't think I'm going to fall for the banana in the tailpipe trick again. Guess that's what I get for thinking because it costst so much it must be a good receiver. I'll probably go back my 90's receiver when the audio goes for good.

My Onkyo NR-3007 has the same problem with the HDMI audio loss. I realized that I have 5 days left on the warranty and took it into Best Buy for repairs. It did last for almost 2 years. Will this happen again?

Guys please help me out

I have a TX-NR5007 with the same symptoms

Last weekend I was decided to do a re-flux like thenextdon13 indicates but when I tried to remove the HDMI board I had some issues with the 3-4 white plugs connected to it, how do you remove those?

Thanks in advance

Thank you very much!

 

Just saved my HDMI board with the oven method and now it's working perfectly again. Cutting the black cable to get the board out was a minor annoyance but I'd say this is such an easy, fast and especially cheap trick on fixing the receiver that I strongly support trying it out if you're experiencing the same problems. I have to admit I was a bit afraid of putting the board in the oven but my worries turned out to be unnecessary as everything went so well. Hope I don't have to do it again since I didn't install any extra cooler for now...
