good luck with that.
you have absolutely no proof of any form why something failed on the board.
if there were a mass issue with defective boards, there would be numerous postings in this forum from people experiencing this failure. and as far as I can remember, you are the 1st person in the SC-57, 55 threads to post this.
as far as Pioneer standing behind their product...let me tell you a story. the subject is Pioneer's x30 models of CRT based RPTV's, one of which I own & went through all this. in that model, there was some defect that showed up for most within the 1st yr and sometimes < 6 months. after a period of time, green lines would appear across the screen and gradually get worse. Pioneer could not determine what the root cause was. but they did provide a "fix" kit to dealers & shops which they felt would take care of the problem. it turned out to be temporary. but Pioneer promised owners that they would be taken care past warranty when they figured out why the problem occurred, why the 1st fix didn't work and what component was the culprit. it was a big thing, since these were $5000-7000 TV sets. from the time I bought the set and by the time it got a permanent fix, about 2.5 yrs went by. not only did Pioneer honor the warranty but the dealer came out again & did the permanent repair no charge to me. as it turned out, the problem was a run of defective color decoder chips from the chip mfg, not the board design. so all owners with open warranty repair cases with Pioneer and dealers got 3 new color boards. the reason it took so long was Pioneer couldn't consistently duplicate the problem and that was because it only effected the sets that had the "bad" chips. once they were able to duplicate & confirm, they came out with a warranty repair kit which solved the problem.
was the experience fun? no, but I knew Pioneer was standing behind it.
in your case, unlike Onkyo which had numerous HDMI board failures, there is no internet evidence of mass digital board failures. otherwise, the Pioneer threads would be full of them
just check Onkyo threads and you'll see what I mean.
to me it seems that you just got unlucky.
just because you had surge protection doesn't ensure anything. nor does "well ventilated". your definition of ventilation may be different than others. I've seen posts from owners who want to allow only an inch or so distance from the top to the next shelf or box it in. did you know yours has a fan on the left side, taking air from the left side and exhausting the top and right side? if the left side was pulling in hot air from other devices or very short distance from a cabinet side + closed doors, then maybe it wasn't as well ventilated as you might think.
my point is not to challenge your setup or understandably being unhappy. my point is that Pioneer is no worse than others and a heck of a lot better than some, i'e. Onkyo on repair track record, reliability and support. just ask Onkyo owners in their threads how they feel about Onkyo support with failed HDMI boards.
over many years, Pioneer AVR's have an excellent track record on reliability & stability. throughout their various designs. I've owned Pioneer receivrs since the mid-80's and never had one problem with them, other than one time lightning surge damage which is obviously not Pioneer's fault.and it was also on surge protection - a $600 Monster Cable power center.
if you want to "never buy a Pioneer again", that's your choice but based on your evidence, I can see no reason why you think Pioneer should be on the hook for it.
to use your car analogy, I wouldn't expect my dealer to pay for an $800 repair once the car is out of warranty and neither should you. unless it's a proved recall situation, which in this case, there's no evidence to support that.
be disgruntled but reasonable Pioneer owners on this forum are not going to take your side Edited by ss9001 - 2/12/14 at 8:09am
