Question Vizio M50-C1—50" 4K Television

Jun 13, 2019
Good Morning,
This TV has been great the last 4+ years, but of course after its extended warranty runs out (at least a year) it literally just bombed. Specifically, we were watching regular cable (Coax, not Digital)
and the image just went blank/black. You can still hear sound, you can see menus ghosting so all the other functions work except for the main image. What I did notice was a bright 2cm circle of pixels in the lower left.
The backlight works fine, just the screen is projecting images. I'm not sure if it's a board or a LCD/LED panel issue. I REALLY don't want to buy a new TV if it's affordable to fix. The idea of tossing this TV seems so wasteful. Thanks!
