My Vizio 50in 4k (D50u-D1) is all of the sudden the corner is getting brighter every few second over and over and over. It wasn't moved or left on with a paused screen. I tried the other HDMI ports, resetting the picture settings and tried all the settings to see if something would change it.
When I turn the backlight settings to the highest it flickers really fast and is less at a steady interval.
So I am fairly sure I know the answer is that the backlight going out. Would it be a relatively safe bet to simply buy a new board, open up the tv and plug it in to likely solve the issue or should I just throw it out and buy a new TV? Any suggestions, tips or advice would be very appreciated.
Below I posted a video to show the issue. Thanks in advance.
