Vizio m55-D0 dark corner - Backlight?
Hello! I have a Vizio smartcast m55-D0 television. Bought it 2 years ago and randomly this dark rectangular area appeared in the bottom left corner of the display. No other issues. I’ve tried power cycling it, changing HDMI cables, firmware updates, etc.
There’s limited info out there about this specific issue with this specific model of TV but it seems like it may be a backlight failure. I see led replacement strips sold online but I just want to be sure this is the problem (and find the correct part) before forking over the cash and spending the time to fix it, as it seems to be a pain to do. Could it also be a power supply issue or something else?
Thank you for any help!
