Can't quite see what you mean, is it the vertical lines you are concerned about? Is the picture otherwise ok?

Looks like a bad panel, maybe worth trying tabs but I would be surprised.

I tried reseting the tab tcon board still same i did look at tcon see if it was getting power.looks like it is also checked voltages on spots from tcon to panel ribbon.they have voltages also two caps c1 and c2 .c2 has 15v and c1 has 3.3v.there is also ka1718 mosfet maybe regulator center tab 1.216 left tab 2.651 and right tab 3.313 fuse 11.87 on both sides.do these reading look good if so that way i can say it is a bad panel.
