Question Hisence TV screen darkening from right to left

[LeeAnnL]

My Hisence TV screen has darkened on the right side. It actually started at the bottom right side and then moved up. Now the entire right side is dark. I'm still able to see the pic but there are issues with darker skin tones and night-time shows or movies.

How old is it?
Still under warranty?

This is unlikely to be a user level 'fix'.
