Edit - took a quick scan and it appears that almost all of the 1 stars are power supplies and some posters had 2 or 3 failures. So that would put it at
9%-10%. Some studies suggest that people are 2-3 times more likely to give bad reviews than good reviews (but other studies suggest its a lower ratio). So depending on what you believe about that the failure rate might be closer to 3%-5%.

10 out of 24 in the 1 star and 2 star category reported power supply failures. So that is, let's call it a dozen because some people were a bit vague about why they returned the unit), a dozen out of 164 in total. 12 is about 7% of 164, so in this entirely unscientific appraisal we have a failure rate of 7%.
I agree that people are more likely to report problems than to give praise, but it is a complex thing in itself and here, the result is so overwhelmingly on the positive side with 93% being happy with their unit, that it seems reasonable to conclude that it is by no means the 'majority' of units which are afflicted with power supply problems. Indeed, although any sort of failure rate cannot be condoned in an expensive component, a failure rate of 7-10% at least puts the odds firmly on the side of not having a problem.
None of this is, of course, any consolation to those who have experienced failures (me included) but no matter what we buy, some will fail for one reason or another. The Onkyo HDMI board failure comes to mind. At the time I had the Onkyo flagship processor and I was one of the lucky ones who had no problems at all. Seems that karma is alive and well and now it's my turn
I think that with complicated electronic gear, some failures will always present themselves. So what is perhaps more important than (unrealistically?) hoping for perfection is how the manufacturer handles the problem. In this case Epson seem to be quick off the mark in replacing faulty units, but some people are (rightly?) not happy with a refurbished unit. However, simply sending out another brand new unit can cause the problem to repeat if the recipient in unlucky enough to get another unit with the fault inside it. In this sense, Epson can't win. If they send a refurb people complain, and if they send a new unit which then goes wrong a second time, people complain. The answer is probably to send the unit in for a warranty repair, but I don't know if Epson are offering this as an option. There is also a question as to what the turnaround time will be. Onkyo acquitted themselves well over the HDMI board failure by repairing faulty units FOC even when they were well outside the warranty period. Of course, it would have been better if the units hadn't failed, but Onkyo offered a good response IMO.
