Question about Sony BRAVIA KDL-46WL140 46 in. LCD TV
Yes, it seems T-Con board board that drives LCD Panel to make picture.
I believe it would be some lose connection in T-Con board or lose connector that is causing such lines.
If tv is under warranty, please call Sony number that would be written on warranty documents or qualified tv repairman can fix it if tv is out of warranty.
Hope this info will help you.
