The "Official" Onkyo TX-NR905 Thread - Page 288

do you happen to know if the replacement boards are any more robust than the original units?

ie...has anyone had an HDMI board go out twice?

As I said before..I have had two 875's that both had HDMI board issues that were replaced under Onkyo warranty
Now...the 905 I bought a couple of weeks ago will likely receive the same repair


Warren

I don't think that when the board goes out ..under Onkyo factory warranty anyway...that they only replace bad caps

In the case of the two 875's that had bad HDMI boards ...the entire board was replaced
In fact one of the units had another issue as well and I was very close to getting replacement unit
In fact the shop that fixed both of mine said that for a warranty repair of that amount...Onkyo required a secondary approval before they would authorize the repair

I will dropping the 905 off at a authorized Onkyo repair facility early next week for its HDMI board replacement
I WILL be buying the 5 year warranty through my via card...it means that they will only pay at max the amount I spent on the receiver...which was $499
But at the very least I won't be out any $$ if( or when) the replacement HDMI board goes out...as long as it is within 5 years anyway

It amazes me how expensive the repair is one these units
No one is going to pay that amount to have one of these fixed..really

I don't know why these units run so hot....even the non Reon equipped units run hot

Warren

I've had my TX-NR905 since 2008, and heat has always been a challenge. To that end I've always kept at least 6 - 8" above it free (with fan venting directly to the outside of the cabinet, used a mesh door for improved airflow, raised it an extra inch off the shelf for better airflow in, and twin 120mm fans sitting on it directly above the vents to quickly draw heat out of it.

The system recently started losing HDMI signal to the TV set after about 20 minutes of being on. When the system is turned off for 30 min, you can turn it on again and video returns for another 20 minutes. I assume this is because of heat, and the other problems I have seem here.

Is there a fix for this? What component/part could it be that is dying?, and is it worth replacing the part?

Would a firmware update improve things? I have never updated it.

I spoke with Onkyo support, and they recommended a system reset, which i did knowing it would not fix it, and it did not fix it as expected. Their support team denied any firmware updates for this unit, which I know is BS going from other posts on this group.

How long is the warranty on these receivers (it's 2.5 years old)? At first the service rep said 2 years, then when i told her it should still be covered she corrected herself and said 2 years. I did use my credit card to make the purchase, and my card does provide extended warranty, so I may still be covered.

Thanks in advance for any advise guru's.

I called the shop I plan to take the 905 to
The tech said they will replace the whole board...however due to the cost it requires a special "sign-off" from Onkyo....he said to expect it to take 2-3 weeks for the repair as the board would have top be ordered in

As I thought he said they had done many HDMI board replacements before
he also eluded that there was sometimes a cheaper alternative...if you didn't have warranty...that had worked for some people

The tech that fixed my 875 told me that the HDMI board replacement work they did would have been more than I paid for the receiver when I bought it new

I also notice that the xx07 models are starting to have HDMI problems as well...I had an 807 that failed...I bought it at MHT...they didn't even try to fix it they just gave me a gift card, for the retail price of the receiver, and told me to pick out another receiver


Warren

Thanks Jon and Warren for your replies.

Seems like my credit card company only doubles the warranty period if the original warranty was for 12 months or less. Therefore they will not assist in this repair.

I don't mind spending $250 on capacitors, as long as this repair will last a while, and that there's not much likelihood of other things breaking.

If I have to replace the whole board, I may as well buy a new receiver, as I paid $1,200 for this receiver, and Id like another receiver that runs cooler than this model if possible.

Seems that Best Buy is the only Dealer/Service provider within 20 miles of my house, so I'll go speak with them to see how they would go about it. Does anyone know?

Thats interesting
My CC company( bank issued Visa Signature card) will add up to 1 year if the manufacturer warranty is no more than 2 years
BUT..you must register the item within, I think, 90 days of purchase
You can also buy a 5 year extended warranty for the item based on its original price
BUT..the CC company warranty will only pay out as much as you originally paid for the item for a repair
No biggie if you paid retail for the item...but something to take in consideration if you paid say $499...like I did

On another note I dropped the 905( that I just bought for $499) at a local authorized service center the other...they said they have done many Onkyo HDMI board replacements before...lol..imagine that

So for the first two years its Onkyo's deal...year 3( and 4&5 if I buy the CC company's extended warranty for $76.00) will only get me a check for $499 from the CC company should the unit fail and have a repair that is more than its purchase price was

You should look at the Onkyo website and select service center...then enter your zipcode. The website will give you the closest places to you
To my knowledge BB does not repair anything..unless you bought their extended service plan...at which point they will ship it to a regional service center


Warren

My credit card is a Mastercard.

I did use the server center locator on the ONKYO site, and it only shows Best Buy repair centers.

So today I went in to Best Buy to check their process. They want me to drop the unit off and pay a $35 fee. They will then ship the unit to their central repair center where they will analyze the error and send quote for repair within 2 - 4 weeks.

I then decide whether to proceed or not. If decide not to proceed I will bring it home and try to repair the Capacitors myself if someone can tell me which are the ones to repair.

It will be out a minimum of 4 weeks from what they say depending on how easy it will be to get the parts.

Has anyone seen a diagram of where the issue resides, and which items may require replacement? I understand that the board is hard to get and expensive, so i would just try the Capacitors.

Thanks, Al

Well...$35.00 is the least expensive "check out" fee I have heard of....
So maybe Best Buy is the best place to go

You can almost bet they will say HDMI board...and I would be curious as to what they say the cost is

I don't know anything about replacing the capacitors..though I have seen it explained in one of the threads here before


Warren

Hi All,

I just got one of these and I am using it with MKSOUND speaker and subwoofer, I can get all the speakers working but am having problems with the subwoofer. When I use the test in the speaker setup I can hear the subwoofer but not when watching anything, any idea on how I might setup to get this working?

Cheers

question

I know there was some talk about this at the begging of this thread...but I don't know if there was a conclusion

I picked up my 905 from the shop...he reattached the HDMI board
That seemed to do the trick...and also makes me think the unit has had the HDMI board replaced in its past

BUT...then on some digital sources I heard a random "chirp"

Took it back to the shop...he played it for a day and could not get it to reappear
He also told me the unit had the last firmware updates


I just got it back home


does anyone know if the bottom of the "chirp" sound was ever gotten to?


Warren

Update

thought that there had to be a way to reproduce it

So..I threw in a blu ray of Bourne Ultimatum with a DTS MA soundtrack

the unit was chirping like crazy
I took my phone and made a video

Then I called Onkyo....3 weeks ago they said they did n't know anything about it

Today...they "found" an update and said they were sending out the CD
Said I could do it myself with a player hooked to the 905 with an optical connection

So..we'll see


Warren

as I said I will post an update once I have the disc

One thing I noticed about the 905...it seems to run even hotter..if thats possible...than the 875 did

I don't have the 875 anymore..or I would compare the two for heat

But I will say this...the 905 gets hot enough, at moderate volume levels, in about an hour as to make it barely possible to place your hand on top of the unit
That is with the unit sitting in a wide open area


Warren

I am not sure how often I am going to use the 905...and frankly buying a fan seems a bit of a pain....especially since other models don't need fan cooling for longevity

If I were a betting man I would think this HDMI board has been replaced in this clearance 905 unit I bought

any stories of a 2nd HDMI board failing?

I see now that forum members are having xx07 models with HDMI board failures

I personally had an 807 that has a failed HDMI board failure

Will Onkyo ever improve this issue?


Warren

My 905 runs hot; but never has shut itself off during operation.

I think the earlier runs had more HDMI board failures. My replacement unit has been stable since day one.

I don't know if I would go Onkyo or Denon the next time around.

I'm wonderning what kind of ventilation those problem units and have. All to often I've seen units crammed into "home theater" furniture with little or no air circulation. My 905 sits atop an open air rack with nothing on top of it or anything to block airflow.

Those HDMI boards run seriously hot... and there are no heatsinks there ...

The things that fail are the capacitors and surrounding bits, not the main processing chips that generate the heat.

If it is a unit which is no longer under warranty, I would fit some heatsinks on there (standard electronic shop bits... using thermal glue/goo to attach them to those chips) - which would easily drop the temperature on that board substantially - literally taking the heat off those other components...

Read the postings in the related 906, 876 threads....

Some people have replaced more than 2 HDMI boards.

I have only replaced one (so far)

bye for now

David
p.s. mine is in a rack with an inch of space on either side, and 2ft of free air above...

That is scary...hopefully no one has paid for replacement out of their pocket
My understanding is that the repair is more than the entire receivers cost

I have had (2) 875's and one 807
All 3 units had HDMI boards go out...all replaced under Onkyo warranty

I did the update they sent me for my 905....still having the "chirping" issue
So back to the repair facility it goes

BTW..Onkyo must have the worst customer service out there
I tried to get through their customer service line multiple times...and when I did the agent could offer no answers....told me all I could do was take it back to the repair facility

Warren

You US folks shouldn't count your blessings!

These have been selling refurbed in the US for around $500 to $700...

Here the refurb. price was $2500 (!!!)

And even though our dollar is now riding high.... the local price is unchanged...

The risk is too high with these to try to import one direct - reality is that you can expect to need warranty service....

Even at the $1000 cost of replacing the HDMI board, these are incredible value receivers. - And at $500....

...well..in your case I guess it seems like a good deal
Though it seems odd that your units cost so much more but the cost to repair is about the same?

Mine is back in the shop...the disc didn't fix the "chirp"
They are thinking its some sort of DSP chip now..oh well

For grin I called Onkyo parts and asked how much the HDMI board assembly
He said MSRP was $1100

As for these being a value...I am starting to question that
The failure rate is very high...it seems that the norm is a failure after 2-3 years.....the norm rather than the exception

you really have to ask yourself how much is it worth to me to have to unwire the unit...possibly have to ship it out...and then wait 3-4 weeks for it
as I said before...every Onkyo receiver I have owned....(2)875's and an 807 have had HDMI board failure


Warren

Hello!

Anyone know what is the latest firmware update for the 905? I was not able to find the 905 in the Onkyo website.

I just checked my 905 and it got the firmware version 1.08


Thanks for any help!!

that is what I have...and according to service department that is the latest
They haven't had a firmware upgrade on the 905 since mid 2008

there is also DSP firmware...so you might check and see if you have latest there also


Warren

Warren, thanks for letting me know!

Hi I have an Integra 8.8 have been happy with it's performance over the past 2 years so mainly have been reading the forums on projector screens and HT builds.
Thought I'd pop into the receiver forums and check out whats up, and to my horror been reading about all these HDMI board failures for folk with the Onkyo x05, x75 line of receivers. Can anyone tell me if the Integra line suffer the same issues? Has anyone had this failure on the 8.8?
Maybe I need to look into getting some fans.

Something tell me the Integra twins are subject to the same failures
