Reviewing this entire thread from start to finish, it shouts "MANUFACTURER DEFECT
The UE22 Error follows a consistent pattern of failure for Pioneer receivers made in 2011 and 2012. No specific model or month of production/manufacturing date has any relationship with this issue in terms of isolating the problem to a particular production run. It has happened to owners who have had their receivers both enclosed and out in the open with plenty of airflow or ventilation. You see that confirmed in this thread.
Although I still do think that the issue is heat related combined with a faulty design implementation I believe some owners may have escaped the EU22 Error as forum member cswiger states:
"having good ventilation (or active cooling if needed) from the beginning could make a big difference in how likely you are to experience a problem." This could explain why the EU22 Error failure has not happened with all owners. Just a theory though.
You have to wonder what design change Pioneer quietly slipped in for 2013 models and forward that eliminated the problem. I would like to see an SC-77/SC-79 opened up and compared directly to an open SC-55/SC57 or SC-67/SC-68 that points to a change in design/build.
I'm going to assume that Pioneer spent a lot research and time to find a winning design, after the discontinuation of the "Ice Receivers". Remember, Pioneer waited 2 years before releasing these new models in 2011 and at an affordable price point that could please the end consumer while also make money for Pioneer. However, they probably did not field test the new design long enough to identify that there actually was a problem after long term use and/or different usage scenarios.
I just hope that Onkyo/Pioneer will consider a "Customer Care Program" for owners of 2011/2012 model years or at the very least an affordable "repair program".
Please continue to report and document your receiver UE22 Error occurrences here so that we can build our case even stronger.
