My tv is less than 2 years old and is getting a dark stripe (for lack of better words) that covers about 25% of tv picture. Can barely see picture through it. What are you going to do to make this right for me?
Try a pixel refresh if your TV has that feature. You can also try a full reset if that doesn't help. If your TV is out of warranty then your options will be repair or replace. Unfortunately, edge bleed and clouding affect all backlit TV's.
