UE22 Special Customer Care Program through Onkyo has officially ended as of January 1, 2020.

Claims submitted on or before December 31, 2019 before the deadline will be processed by Onkyo support.

This thread will continue to provide community support to affected UE22 Pioneer receiver owners.




Updated on August 30, 2019

New information from OnkyoUSA's technical support team. Post number one has been updated.
UE22 Error Master Thread-Pioneer, are you listening?


UPDATED ON MARCH 21, 2017
Please scroll down to "Update on the cause of the UE22 Error" and Onkyo/Pioneers New Program Note: United States and Canada Only

Updated on July 10, 2017

Early unconfirmed reports are that Onkyo/Pioneer is covering repairs for this defect until the end of 2018.


^^^
This statement will be updated shortly since affected users are reporting that Onkyo/Pioneer are still accepting claims as of July 2019 with no program end date.

Updated May 15, 2019

SuperZ has reported that Onkyo/Pioneer continue to accept claims for HDMI board replacements. See below:

UE22 Error Master Thread-Pioneer, are you listening?

Updated on July 28, 2019

AVS Forum member "calavs" reported that Onkyo/Pioneer has approved him for a one time repair for the UE22 error issue.

UE22 Error Master Thread-Pioneer, are you listening?

Updated September 2nd, 2019

Onkyo support has now stated that repairs are only being done while parts inventory is still available. Certain models no longer have spare parts for repairs.

As an alternative, a reduced priced trade in receiver is being offered depending on stock availability. This applies to both American and Canadian claim submissions.



However, I'm trying to petition Onkyo/Pioneer to have the UE22 repair program lengthened to the end of 2020/2021. Updates will be posted here on the status of this petition.

July 15, 2015-I'm starting this thread to document and track the UE22 error that is occurring on affected 2011/2012 Pioneer and Pioneer Elite Receivers.

It is hoped that by bringing it to the attention of Onkyo/Pioneer Electronics that they will be committed to quality and customer service by addressing this issue in a timely and fair manner for affected owners.

This thread is not meant to trash Onkyo/Pioneer or be sarcastic which may take away from finding a solution to the problem. Instead it is hoped that affected users and knowledgeable people can bring a better understanding to what is going on with this error code and possible causes and solutions. In other words please be civilized and respectful in your choice of words (Please read AVS forum rules for more information).

Background Information about the problem:

Affected users have reported that when this problem occurs it does not happen suddenly but over a period of months before eventually the receiver completely fails and will not work. Reports of users getting the error code multiple times and then having to reset the receiver by applying the factory reset or unplugging the power and eventually months later the receiver produces no sound and simple knob and button commands does not respond. Also, the UE22 error usually happens at the worst time, just after your warranty has expired according to many owners comments on the internet. Just Google UE22 error and you will see all the comments and frustration of affected owners. I got tired of reading the posts of the many owners who spent good money on their Pioneer receivers only to walk away and move on from Pioneer because they got burned with this issue when they could not afford the out of pocket repair costs because the warranty had just expired.

For owners impacted with this issue while under Pioneer warranty, they have been fortunate and had their DIGITAL MAIN ASSY board (or main digital board) replaced free of charge and they received their receiver back with no more problems. However, the problem with this is that its the most expensive part of the internal boards ($400-$500 plus labor) and when you have to pay out of pocket it becomes hard to absorb that kind of a cost. It is hoped that Onkyo/Pioneer will find a fix for owners by isolating this issue to a specific defective chip and help affected owners by having that chip replaced instead of replacing the most expensive board from the internal electronics. This would be the most logical fix and cost effective approach to dealing with this problem for Onkyo/Pioneer.

Forum members posting criteria:

Please state the following:
  • Pioneer receiver model/number
  • Build date (MFD: month & year),
  • Purchase date
  • UE22 Error display date
  • Receiver positioning/placement statement
  • Indicate if your Pioneer receiver saw low, medium, or high usage in your set up
  • Description of your experience with the UE22 error and the events that led up to your Pioneer receiver eventually failing.
You may also have some insider or technical knowledge that can shed light on the UE22 error and that would be most welcome.

This thread will be updated as the information comes in and will be compiled to better understand the problem and find possible solutions.

Hopefully someone senior at Onkyo/Pioneer will see this thread and respond in an appropriate manner for their fan and customer base.

Thanks

Update on the cause of the UE22 Error



After researching, analyzing, and hypothesizing the cause of the UE22 Error and through a diligent community effort here on AVSForum the cause of UE22 Error has been found. The root cause has been isolated to defective Texas Instruments DSP chips that globally affects all Pioneer and Pioneer Elite receivers manufactured in 2011/2012. See post# 100 and 848 in this thread for the background that identified the cause of UE22 Error. See post#2 where the defective DSP chips are located.

Edit: OnkyoUSA's technical support team has given new information on this thread that UE22 only affects certain 2011/2012 models. However, no further information was given at this time. Updates will be provided as more information comes in...


Please note:
Heating the DSP chips will not correct or fix the UE22-Error issue. It is only a temporary solution. The DSP chips are defective and must be replaced via a main digital board replacement with the updated DSP chips.


Do Not Attempt A Firmware Update when UE22 Error occurs. It will cause additional problems that may complicate the repair of your affected receiver. There is a high risk of corrupting the DSP firmware when attempting an update post UE22 display.

Onkyo/Pioneer in the United States and Canada has a new program in place to help Pioneer and Pioneer Elite affected receiver owners by offering a discounted refurbished Pioneer receiver (subject to available inventory) or have Onkyo/Pioneer replace the main digital board with updated Texas Instruments DSP chips that does not have the defective TI chip set (subject to parts availability).

Pioneer UK/Europe/Asia/South America's position on helping affected owners is unclear at the moment.

Thanks to AVSForum member zone33 for posting a step by step repair procedure on how your claim will be handled. See below:

Onkyo/Pioneers New Program

Step by step repair

Hi everyone I just wanna give a few tips on how to make sure your effected receiver gets set up for a repair or replacement through onkyo/pioneer.

Step 1- This isn't technicaly necessary but is a useful start. Go to onkyousa.com. Click the support button. On the page that comes up next click "Email Us" on the left side of the page. Fill out the information and mention your UE22 problem and that you heard there is a program to resolve it and would like more information. I got a response within 2 days. You will be told about the program and to send the photos to pioneer/onkyo parts department email (receipt, UE22 pic, Serial # pic) . The useful part about step 1 is the replier is a technical specialist and his name is provided at the bottom which we'll use as a reference when sending photos to pioneer parts dept.

Step 2- Make an email. Headline the email with your name and Model number. Parts department email is (( parts @ us . onkyo . com )). Mention your technical specialist's name and explain you have the UE22 error which you are trying to get repaired. Info required in this email are photos of purchase proof from an authorized dealer, photo of the receiver showing ue22 and a photo of your serial number on the back. 3 photos. Also need to provide phone number and home address. No receipt? If you purchased from store or card where you can pull up purchase history and screen shot that, it will be usable determined by parts dept. Review and send email.

Step 3- After the 3rd day of no reply I called the pioneer/onkyo parts department. You may want to expedite by calling sooner. Expect to wait 10-15 min to answer. Business hours are 9:00 am - 5:00 pm weekdays. The number is 1-201-785-2399 . Tell them you are waiting on a response to email. They will search by your name you put in the headline. They will put you on a short hold while they review the email. You will be given the verdict. If all is clear you will be given the option of a free repair or 1 or more choices to buy at discounted price trade, depending on availability. You choose right then. After chosen you will be given a return number to track and file.

Step 4- get the return box and follow directions. You will have a working receiver within the next 3 weeks and you will feel like companies actually care about their customers still. good luck!

Step 5- Enjoy sound.

Important Information relating to your UE22-Error claim

When submitting your claim through Onkyo ensure that you indicate that you want the correct main digital board installed that has the updated DSP chipset with the part number D810K013DZKB4 (2011 model year replacement) or D808K013DPTP4 (2012 model year replacement).

The "D" Version.

Verify this again with the service centre location that they installed the correct version before they send back your receiver.

http://i274.photobucket.com/albums/jj276/randomrat/2015-06-08 01.13.35 edited.jpg

https://www.avsforum.com/forum/attachment.php?attachmentid=2291156&d=1506878454
https://www.avsforum.com/forum/attachment.php?attachmentid=2301308&d=1508447758
https://www.avsforum.com/forum/attachment.php?attachmentid=2350770&d=1516848879
https://www.avsforum.com/forum/attachment.php?attachmentid=2591524&d=1563309830

If you receive back your receiver with DSP chipset D810K013BZKB4 ("B" Versions) and D808K013CPTP4 ("C" Versions) your receiver will fail again in 2-3 years.

These chip versions were identified by TI as prone to premature degeneration or aging http://media.digikey.com/PDF/PCNs/Texas%20Instruments/PCN20121114000_Obs.pdf and was corrected in the next generation of TI DSP chips, 2013 (2nd Pioneer receiver production run in 2013) and forward. This means a small batch of Pioneer receivers in the lower end models received the faulty chips in the very first 2013 production run but was corrected in the second production run in 2013 and going forward.

Note: Lower end receiver models will have 1 DSP chip and higher end models will have 2 DSP chips.

I have(had?) an SC67 that I just loved so much I have been keeping an eye out for the next round of Elite receivers. Unfortunately, during the weekend it experienced the dreaded UE22 error.:mad: I updated the software the first time. That seemed to do the trick, but two days later it died again never to be awoken again. Of course, this happened 3 months outside the warranty period.

I get it that any receiver model can experience premature failure, but while looking for a fix I read post after post of people who had experienced the same issue. This is a manufacturing defect. Unless Pioneer act to correct this issue by agreeing to fix receivers outside of warranty, I will never buy another Pioneer again. Already looking at Denon and Marantz brands for my next receiver. Until this weekend that was not on the docket.

Pioneer screwed me too.

I bought an Pioneer Elite SC55 in February of 2012. The UE22 code sprang up for a few weeks around April of this year, but magically disappeared until yesterday. The code reappeared and hard resets have done nothing to fix it. I've tried to do a software upgrade, but to no avail. It is noteworthy to point out that I bought TWO Pioneer Elite receivers at the same time in 2012- one for my bedroom(SC50) and one for my living room(SC55). They BOTH gave me the UE22 error. I spent $1,600 on the 2 units. Pioneer, I hope you're listening. I'm posting this and then I'm posting this message to my Amazon review as well.

Went to alot of trouble to get signed up here and ADD to the absolute disgust that I have a $800 boat anchor brought to me by Pioneer. SC-63 sold by Amazons UNAUTHORIZED dealer in October 2013. Not even 2 years old and I have the UE22 error with no recourse but the expensive burden of paying for the repair myself. This borders on criminal. My sole goal is to post this story as many places as possible. "These" people count on the story being buried. I may not make any difference---but I at least tried.

javaguy,

Welcome to AVS forum. Sorry to hear about your SC-63 situation with the UE22 Error. Your not alone as you can see with other negative reports of how many Pioneer receiver owners got robbed of the full use of their receiver. We share in your anger and frustration that Onkyo/Pioneer has not moved to deal with this pattern of receiver breakdowns that cannot be linked to owner behavior or occasional quality control issues.

The evidence is clear. We just need Onkyo/Pioneer to investigate and take action that is needed on the owners' behalf to maintain some type of credibility for a product that they made and sold on their watch.

Don't want to be pessimistic...
But... :rolleyes:
Last year the Pioneer home audio division was sold to Onkyo which now is part of Gibson. @ that time the majority of Pioneer's AVR engineering/development team were laid off...

IMHO..
The only possible solution would be to group together all of the Pioneer users with this error and go back to Onkyo for a possible fix...


Just my $0.02.... ;)

When Onkyo purchased Pioneer they inherited Pioneer's issues. Completely agreed, M Code.

My 1527K Receiver developed the "UE22" error about a month ago. Receiver was 26 months old at the time and out of warranty. Brought it in for repair and it requires a "main digital board" @ $500.00. Unfortunately the part is back ordered which only adds to my frustration and disappointment with this product. Sorry I refused the extended warranty plan now, at the time I thought the chances of failure were slim to none. I am on the verge of cancelling the repair and going with something else - too bad as I really liked the unit, in fact I also have a 1528K, wonder if it will die too.

Hi all,
I have a Pioneer Elite VSX 60 that now has a UE22 Flashing Error.
Previous to this the Audio went out with no Error.
I took it to my local Pioneer Authorized Service Center and after a week I was told that the "D" Board was bad
and it would cost $617.00 to repair! Ouch!
I contacted Pioneer and I was told that because the receiver was "Out of Warranty" It would be my responsibility to repair it.

I picked up my VSX 60 and I connected it back up and instead of using HDMI 1, 2 & 3 I used HDMI 4, 5 & 6.
The Audio actually crackled a bit and came back, it worked for a week before I had to go out of town.
When I returned a week later, I had to turn the VSX 60 on and off a number of times until the audio stayed on but I got a flashing "EU22" on the display.
I am afraid to turn it off and it has now been "ON" for a week straight with the Audio working fine and EU22 flashing away!
I guess I'll see how long the audio stays on.

Previous to this Elite VSX 60 I had a Pioneer die via HDMI PCB but it was the opposite I had Audio but no Video.
After contacting Pioneer (in 2012) I was offered 3 different Pioneer AV Receivers at a large discount.
I purchased my now sick Elite VSX 60 for $250.00.
I wrote to Pioneer asking for the same consideration that I received in 2012 but Pioneer turned me down stating it was a once in a lifetime consideration.
Maybe it's because Pioneer is now owned by Onkyo and their policies are different, I don't know.

I'm sure that I am on borrowed time with my Pioneer and it will eventually die completely.

Side note: When I picked up my Pioneer I asked the Tech what receiver manufacturer does he like as a replacement?
He replied that he used to like Yamaha but that their quality has really gone down, he also told me that he liked Pioneer but they have been purchased by Onkyo and he never liked Onkyo and thus expects Pioneer's quality to go down.
There have been so many people laid off at Pioneer that when he calls for tech support their is only one guy left when there used to be a lot of support technicians at Pioneer.
He got called away for a phone call and that was all that I could get out of him.
I wanted to ask about Denon and some other manufacturers.

So now I am unsure as to exactly what AV receiver manufacturer will be my Pioneer replacement!!

Good luck to us all!

Bud B


Here is the complete story:
Reply from Pioneer:

Your contact to our Customer Service Department has been forwarded to me
for response.

Your request has been carefully reviewed, and we do understand your point
of view. Within the terms of our Limited Warranty, Pioneer will pay for
repairs required due to a manufacturing defect during a period of two years
from the documented date of product purchase. It is our intention to be
fair to all of our customers while honoring the terms of this warranty.

The accommodation you describe that was provided by Pioneer in 2012 was a
special, one-time accommodation, and we regret that we cannot provide that
same special accommodation again in 2015. Accordingly, because your VSX-60
is no longer covered under our Limited Warranty, we must respectfully deny
your request for assistance with the cost of repairs that may be needed on
the unit.

While Pioneer is unfortunately unable to provide the requested
accommodation, we thank you for your business, and for the opportunity to
respond specifically to your concern.

Bryan,
Thank you for your response.
I understand that if I repaired the unit I would do so at my cost because
it is out of warranty.
The moral of my story and reason for writing to Pioneer was to find out if
anything could possibly be done to help me, especially after learning that
a receiver will cost what it's original MSRP was to repair in 3 years time!

My current Elite VSX 60 AV receiver was offered to me via Pioneer Customer
Support because the Pioneer receiver that I had at the time died.
The receiver that I first had was not an Elite but just like my current
Elite VSX 60 it too had a HDMI board fail!
It had no Video only Audio, just the opposite of this Elite VSX 60.

When I wrote to Pioneer unlike your response to me which was, "I do
apologize for this but since your unit is out of warranty it will need to
be repaired at your cost."
I received a much different response from a woman (I think her name was
Nora?"} She apologized for my loss and assured me that Pioneer equipment is
designed to the highest standards and expected to last much longer than my
receiver did.
Because it was out of warranty the best that she & Pioneer could do for me
(A dedicated Pioneer Customer with over $4,000.00 worth of your products)
was to offer me a replacement at a much reduced cost.
She gave me three receivers to consider each at a different cost, the Elite
VSX 60 was around $250.00 and because I already owned an Elite VSX 53
receiver, I decided to go for that.
She took my credit card information, processed the order and my current
Elite VSX 60 was shipped to me directly from Pioneer.
If needed I can find the paperwork.

Fast forward three years later and again I have a bad HDMI board in my
Pioneer receiver!
I was hoping for a much more satisfactory resolve to my current problem
than what I received from you!
Am I happy in the fact that I am replacing Pioneer receivers one after
another because of bad HDMI boards, absolutely not!
The Technician at Lakes Electronics said that many times it is because
boards are placed above power transformers and they bake like being over a
hot plate.
Whatever the reason, the fact that I have two receivers die prematurely
(which I consider 3 years to be!) due to HDMI boards raises some serious
concerns with me.
I have always been a strong supporter of everything Pioneer but if this is
the best that I can expect, over $600.00 in repairs for a $650.00 receiver
in 3 years!
That is totally unacceptable!

Please get back to me and let me know if there is anything further that can
be done to resolve this situation.

Sincerely,
__________________________________________________________________________________________________________

Ue22

My VSX-52 would periodically flash UE-22 for a couple months and then one day just crapped out. Purchased mine in 2012 so of course (like everyone else it seems) it is also out of warranty. Sold home audio/video while i was finishing up school several years ago and I used to sling the Elites left and right. Feel bad thinking that a majority of those are bricks well. Don't see how Pioneer/Onkyo can think this sorta thing will go unnoticed. With the amount of online "research" that is done these days you gotta think that folks are coming across this UE22 horror story and will be shifting the focus of their wallets elsewhere. I'd think twice about accepting a FREE unit with Pioneer badging, let alone shelling out $600 on up for one at this point.

Same problem, did find a web site where people are getting a temporary fix by using a heat gun on the DTS chip for 20-30 seconds. I did this and it worked for a couple of months, then had to redo it but only gut a couple of weeks out of it. Just had to do it again.. but not expecting it to stay fixed for very long.

I would like to thank all those who have submitted their UE22 Error incidents for this thread to date. It is hoped that other affected Pioneer owners would share their story here so this thread can gain more traction with Onkyo/Pioneer.

I believe that the chances are good that Onkyo/Pioneer will respond to the many failed Pioneer and Pioneer Elite units manufactured in 2011 and 2012 based on a decision made by Onkyo on August 19, 2014.


Please see below Onkyo's Customer Care Program for failed receiver units between 2009 and 2012:



Onkyo USA's Terms and Conditions
TERMS AND CONDITIONS FOR REPAIR OF RECEIVERS EXPERIENCING A LOSS OF AUDIO/NETWORK CONNECTION CUSTOMER CARE PROGRAM

This loss of audio/network connection Customer Care Program is available only to residents of the US and Canada who purchased their ONKYO brand receivers from an Authorized Independent Onkyo Retailer or from shoponkyo.com
This loss of audio/network connection Customer Care Program is available only for a limited number of Onkyo Brand receivers manufactured between 2009 and 2012 that may experience loss of audio or loss of network connection.
This loss of audio/network connection Customer Care Program will repair receivers affected by this no audio/network connection issue. This Program expires on December 31, 2018 or the date that the eligible repair or replacement is made by Onkyo or its designated Special Program Repair Center. All other terms, conditions and limitations of the original limited warranty shall continue to apply for the duration of the original standard limited warranty.
The limitations on Onkyo’s repair obligation as provided in your original limited consumer warranty shall continue to apply during the original warranty term to any other claims for warranty service.
Repaired products under this Program will receive a 90-day extended warranty on the repair that is made. Onkyo reserves the right to replace any receiver entitled to the benefit of this customer care Program with a new or factory reconditioned receiver of the same model or one having comparable specifications.

Also, see the actual AVS thread below that details and tracts the Customer Care Program for the failed Onkyo receiver units.

http://www.avsforum.com/forum/90-receivers-amps-processors/1652514-onkyo-acknowledges-failed-units-extending-warrranties-until-2018-a.html

I see many similarities with the Onkyo and Pioneer failed receivers in that you clearly see that it was a manufacturing defect that could not be connected to owner use or handling in any way.

Hi guys,

I made a post on AVForums SC-LX85 owners thread about my UE22 issue on how I "fixed" the problem: https://www.avforums.com/threads/pioneer-sclx75-sclx85-owners-thread-part-2.1702219/page-4

Well, I'm back to square one. Just like johnnybwis, it has actually now been the THIRD time I've taken a heatgun to the DTS chips because after a few weeks the same problem comes back again. I currently have the unit sitting on my workbench with its top off, and i'm ready to have one more go with the heatgun + stick some heatsinks on top.

To find that there is a UE22 Master Thread upsets me a bit - I was always under the impression that Pioneers receivers were well engineered and built to last. Does anybody have the service manuals to hand, I'd like to take a gander through it and remove the digital board from the chassis.

What's confusing me is why are the DTS chips causing a UE22 error, an error that implies a firmware issue...? Surely the fault would be on the EEPROM chips or the like? Does anybody know what these two chips with white labels do? I have a feeling (with no evidence) that they store the unit's profile settings.

These two here.





I've just cut an old heatsink to go on top of them. Haven't got round to reflowing the chips yet.




UPDATE:
I've done the reflow and attached the heatsinks on using some thermal adhesive - unit powers on without error. Only time will tell how long it takes for the error code to come back...

Those two chops with the stickers are the firmware chips. The sticker inevitably states the part number and revision preprogrammed on them.

The error is not in the firmware chips. The error means the main CPU cannot get the firmware revision. It does this not by reading the chips, but by talking to the processors in question and asking them. The two DTS chips are DSPs (the also have Dolby on them) and on power up, likely under control if the main processor, they boot up from the firmware chips.

The main processor boots the two DSPs, then waits a bit for them to initialize. It then begins talking to them over some interface, getting their version numbers and other details. Here, it means it failed to do so, which usually happens if the processor crashed. Given re flowing them got it working, most likely there was a bad solder joint, or maybe heat cracked a joint. That bad joint either caused errors on the memory interface reading the firmware and thus crashed the DSP so the main processor failed to communicate, or the interface itself was flaky. Re flowing the DSP thus improved the electrical connectivity.

I am adding my VSX-60 Receiver to the list as well. I have been having mini sound breaks one point. then the sound completely gone. I turned it off. It came back the next day and it was fine for a couple of months. The other day sound interruptions started again and now is gone completely for good. UE22 is flashing on the screen. I owned Pioneer years ago . it was a great then. This would be my last purchase ....

Just thought i'd report back on how things are going after the heatsink addition. Since my last post, the receiver has been playing the Inception blu-ray on endless repeat, and since 4 hours ago things were dandy.

Then I decided to point my 40W desk lamp, about 16" high, towards the decoding chips to see how it'd react - the reason why I did this was because I thought A) i'd push the unit to see how it'd cope and B) the cabinet that this unit normally sits in gets warm when both the receiver and the HTPC are running. I have gotten fed up of taking this unit out of the cabinet so I recently ordered some cheapy banana plugs to make life easier. Anyway, about an hour ago the UE22 Error came back but the audio was still going. Switched the unit off and back on again and the error went away - audio continued to play with no crackling.

Does this evidence strengthen the idea that the UE22 error is to do with dry solder joints, and that heat is causing the problem to re-occur? Explains why some people leave their units alone for a while to find that the error disappears when they power the unit on.

For the heck of it, i've now installed a 40x40mm fan and used some Kapton tape to help channel air through the heatsink fins. The fan will be powered via the 12V rail from my HTPC which usually sits on top. For testing purposes i'll probably hook it up to a 12V transformer.

Yes, I'm clutching at straws, and whilst most people would just go out and get a repair or buy another unit, I'm a (just graduated) student with an interest in hi-fi/audio who saved all my pennies to buy this on the day of release. I'd rather do some DIY/have an argument with Pioneer to keep this going until I can afford something shiny, but i'll be looking elsewhere...
