@save1028 possibly a bad t-con board. It would help if you can post some images of what your screen looks like with those lines. Post some images with your question by using this guide. You will eventual have to remove the back of the TV (after you unplug it) and check things out. Check to make sure that all the cables are properly seated and not corroded. Check the boards for any domed or leaking caps as well as other obvious signs. Again, posting some images of those boards will help us to help you.
