Vizio LED TV Backlight Fix - LED Driver Board Replacement

Backlight Out On Your TV? Try This Before You Replace The LED's!

If an entire quadrant of the LED backlight on your TV has gone out, it's possible that you have a driver board failure and not burned out LED's. Look for a uniform outage, not sporadic dimming or a single dim line (suggesting LED individual lights or entire LED strip failure). If your outage looks similar to mine, taking up 1/4 of your screen, try replacing your LED driver board.
