Question Tv with sound and super dim picture, won’t let me change brightness

[livefreejs]

I own a Westinghouse flat screen, I turned it on the other day and out of nowhere the screen is incredibly dim to where the screen is almost black. I was able to pull the menu up and go to brightness but even at 100% there’s no change...any ideas?

Try sending it to warranty and see what they say. I think its a faulty display
