Hello Joe, my name is ***** ***** I'll assist you. I'm sorry you're having trouble with it.
I need additional info to troubleshoot the issue.

- Does screen glow/ show backlight when turn On TV?

Thanks Joe for the info.

Do you notice the screen changes its black tone when turn On the TV?

OR look at vent holes at back of TV for bright white light for backlight check?
