Hi,

It looks like interlacing problem, but I think Sony have just bad up-scaling.

Try write email to technical support,

this is general problem for both model 2012 :

KDL-40EX653 and KDL-40HX753.

I saw already few complain about.

It's happen to my KDL-40EX653, I wrote before:

I just return my KDL-40EX653.

Sony only good for High definition 1080 or 720.

if you watching DVD, digital TV (576i) , let's say standard definition,

take Philips or Samsung,

Those TV more universal, it's good for any resolution SD and HD.

I think it might be what is more often referred to as 'vertical banding'. You can google that and check if it's exactly that.

It's a very widespread problem with LED LCD panels, it varies a lot on how strong it shows. Most often you can see it when watching something with panning on an almost one color surface, such as football. You see these brighter vertical lines not being in sync with the action.

I have it too and haven't found any resolution or nor has Sony helped even as much as to reply my emails and messages. You can't fix it, some say some picture settings might lessen the effect, but at least I haven't found any really good ones. Guarantee-wise I've heard that even as very bad it's most often not fixed and it's considered to be normal, I believe it would require changing the whole panel.
