Hi, @DeMark
Thanks for posting, and welcome here in the Roku Community.
We see that you're having display issues with your Westinghouse Roku TV, and we'd like to discover how this can be addressed. Could you try to put a flashlight directly into the screen if you're able to see a dim light of the display or see a pitched black display? Also, when did you first notice this issue occur, and what probable changes might have caused this?
Please keep us posted.
All the best,
Kash
