    Sony KDL-52NX800 Half of Picture

    Hi Guys.

    I have a Sony KDL-52NX800 that has developed the following issue. It appears intermittent... failed about a month ago, when I turned it on. I shut off, took a look in the back (at the boards), didn't see anything.



    Panel issue??? I hope not, but thought I would ask anyways since I don't really see a whole lot on the web for this model. Maybe it wasn't a common model back in 2008(ish).

    Thanks in advance for any help.

    Did you already try reseating both ends of the cables between the T-CON and the LCD panels?

      I'm going with T-con based on a similar issue I had with the 46" version and also another issue that my friend had with the same 52" one you're looking at. The 46" I fixed had a split screen problem. Not as defined as yours but exactly 1/2 was distorted. Same side as yours. The 52" my friend had was experiencing odd ghostly looking lines throughout the screen but it too was a t-con issue. Sharp Panel in this series BTW.

        Thanks guys. I will try reseating the cables from the T-con first... if that doesn't do it, maybe I'll order up a T-con board.

        I was wondering (and hoping) it wasn't a tab bond issue... like I had with a 52" XBR series a couple years ago... where the screen was split, but that has 'ghosting' too. That's what made me wonder and think it wasn't a T-Con.

        I did see it was a Sharp panel too... funny!

        Thanks again, much appreciated. Will report back.

        Take care.

          i would say screen tab as there seems to be screen retension in the middle where its dark and not refreshing

            Well, a T-con would be worth trying... but I'm leery, due to what comptek has stated. Looks eerily like the 52XBR I worked on a year ago. However, I thought the tab bond issue was specific to those XBR models, and I thought Sony "fixed" that issue with later models. Maybe not.

              I actually missed the part in your first post about it being intermittent. That makes me a bit more skeptical about it being the t-con. Mess with the connectors and tabs first and see if you can make the problem come and go, or even change at all.
