Solved! Upper Left Corner Dimmer than the Rest of the Screen on Vizio M60-C3

Jan 25, 2019
The upper left corner of my Vizio M60-C3 is dimmer than the rest of the screen. the backlight is not out completely but there is a 10x10 inch square that is dimmer. Could this be an issue with the LED driver card?
Some of this is not uncommon unfortunately. If it really bothers you, return it, but nobody can guarantee the replacement won't have the same problem. Your call.
