i have the same problem, apparently the LCD panel needs to be replaced and this will cost more than the tv is worth... Advice is to not buy a sony again, because this is a common problem and they wont extend the warranty, even if its 2 weeks after it runs out...

This also happened to me and may continue to get worse... If it goes away for a while after warming up, then it is the same problem... The LCD panel is probably going out, when that happens the cost to repair it is more than the tv is worth... If it is in warranty then you can have it replaced or fixed.

Testimonial: "You were so right. Thanks."

Hi,
Basically it is problem of lcd panel (screen) but some times T-Con board (it is also part of lcd panel) replacement fix the issue.
T-Con board is located top center of lcd panel at back and need to take off back cover of tv to see it, this board would be covered under metal shield.
Expertise are required to replace this board and novice can damage lcd panel (screen) permanently.
Thanks.
