Summary: Purchased the XBR46HX929 direct from Sony after a run-around from Vizio trying to purchase THEIR full-array set (held my funds for almost two weeks then cancelled with an "out-of-stock just when 'processing' was completed" excuse). I also purchased the Proforma 460, 2in1, TV stand on Sony's website when I bought the TV. The description claimed compatibility.
Summary: In sum, expect the beautiful display to be embarrassingly scarred after an inexcusably short amount of time, and then having to wait weeks for Sony to fix it. Picture looks great until screen fails - and it will. I haven't had the TV longer than 90 days, and a blue vertical stripe has developed running the entire height of the screen. I did some online research and this is a common problem.
Issue with XBR46HX929 -- Sony Support is bad (; not easily reachable or accountable)

Summary: I purchased Sony XBR46HX929 TV a month ago and it ran into issue; On power on TV comes online for a few moments and shuts off automatically and comes online again. This process repeats for a 3 to 4 times and finally TV shuts off. I tired to raise a service/rma request through Support contacts/online chat but they couldn't help. Support didn't even bother to create a CASE report for future reference and follow-up for the same issue.
