Vizio just called me to let me know they had received the Best Buy receipt I faxed them last Friday (just to get it in their files and have it on record in the event of any issues down the road - I also faxed one to Square Trade).
Anyway, during the course of conversation I found out two things (perhaps what many of you already know):
1) The Serial Number sequence (e.g. SN49, SN50, SN51) represents the week it was built last year 2012
(49th week, 50th week, etc).
, whom I quoted in my last post with a SN04
, that set was built the last week of January 2013
., while mine with SN50 was built in week 50, or the second week of December 2012
2) According to the rep I spoke with, of all the Vizio E601-A3s "out there", there is a failure rate of "less than 3%"
)...ergo, 97 of 100 built have no technical issues.
