12 little horizontal lines in Sony Bravia KDL-52W4100

I have a Sony Bravia KDL-52W4100 which has 12 little horizontal lines in the top and going down to the middle screen and the same lines over to the right on the edge. They are 6 inches wide and about a 1/16th inch tall in the middle and half the width over on the right edge. It is 3 months out of warranty. Is it the LCD panel or some sort of controller? Thanks! Ron

    I am the one who submitted the problem. The tv is now fixed! I ordered a box of parts taken from a tv exactly like mine on Ebay and luckily there was a t-con board in it. I replaced it a few hours ago and now the tv works perfectly! Thanks to the 2 who provided solutions. I respect the tv service industry very much! Thanks also to Royal Electronics in Port Orange and to the technician Mark, who diagnosed the problem. They did all they could possibly do on their end.



    Thanks!

    TV IS FIXED! Yes, it was the lcd panel, but only a part of it - the t-con board. I ordered a box of parts on Ebay, which came from a set like mine and luckily it had the board in it. I replaced the board a few hours ago and the problem is gone! Thanks to all tv service technicians, and especially Mark of Royal Electronics in Port Orange, FL, who looked at the tv and called me back and to tell me what the problem most likely was. Thanks everyone!
    Sincerely,
    Ron

We have the same exact tv and it is not even a year old. we are told that it is the display panel and it is a well known problem with this tv. we were also told that there is a shortage of these parts. they had 283 on order, but only received 35. you need to call sony and tell them that you have this problem. they should warranty this for you even if your tv is 3 months past the warranty period. since this is a well known problem with this tv, keep on them.

It's the panel. Mine took a sharp force trauma when it fell only 1 foot onto something very pointy (a cellular external antenna) and it looks like it got shot by a bb gun. And it has lines kind like what you are describing.

You can't fix an LCD tv with this kind of problem. You just can't. The LCD panel cost more than a new TV. I know I asked the local Sony Shop to just order me the LCD panel. It was over $900 on a $600 retail TV. I was going to replace it myself ... I fix laptops ... but not at that price. So far I'm just using it as it is, until I want to, and have the $$$ to buy another one.

Good luck on yours.

(a laptop lcd panel repair costed over $300 by the way on a $600 laptop with a few years age on it. I did it mainly as a learning experience. But never again.)
