Beware the backlight bleeding on ALL versions of this model.
16 April 2012
Summary: I did my research before purchasing a new LED-LCD and found this one had some of the best things said for the price. Even in the forums people seemed to be pretty happy with it save one issue: backlight bleeding or "flashilighting".
Summary: Sony replaced my kdl46hx800 with the kdl46hx729. The picture looks good but the edge lighting led causes horrible backlight bleeding. very easy to spot. Sony technician came out to look at the Tv and told me that he would contact Sony for me.
Summary: My TV which is just about 2 years old and it started flickering and now the picture just sticks and starts overlaying.. I called up customer service and after trying all they suggested they said if it costs me more to repair, they can provide me 15% discount on new TV..
Summary: I bought this TV on 10/24/2011, up until last 08/2014 I was satisfied and I didn't even know that a curve UHD 4K TV was created. Yes, I know where have I been but like any relationship when things go wrong you begin looking again.
Summary: One and a half years after having this TV, lines started appearing in the screen. SONY says its out of warranty, I say it was a defective design - search "SONY line in TV!" Don't buy this TV because it will fall apart!
