Wow... What a wonderful post with all it's copious notes and extensive details about the exact nature of the problem.
Sarcasm aside, it's impossible for anyone to know whether or not they've been in that situation because you don't give any details ABOUT the situation. Unless you're just asking about whether or not people have had their PS3's crap out on them, in which case, yes plenty of people have. Probably not as many as 360 owners, but the number is higher than 1. I think estimates are PS3 failure rates are around 10-15%... Might be less with the Slim models, might be more. Haven't seen any actual data.
But I believe Sony has a no questions asked repair service for about $150. Basically what happens is they send you a new system that is as close in spec to your old one as they have on hand.
I bought PS3 last year. It worked fine untill one day suddenly it just went out. it is giving message which says that there's some problem and i should contact the technical team of PS3.
Let me know if any one has faced or is aware of this scenario.
