You're likely still in the manufacturer's warranty. I would recommend filling out an online request form and having a technician come out and inspect the unit.
You can find that form here:
This tv is only 3 months old and has been nothing but problems.
The newest is - there is a wide bar going vertically down the mid right side of the screen that is a lighter color than the rest of the screen. When we turn on the tv it is about the same as the rest of the screen, then gets lighter the longer the television is on.
How can I fix this? I'm beginning to dread turning this tv on.
