Screen all of a sudden won't display picture

I did the flash light test. I can see the picture is there even though the screen is black. According to most people (i.e. the internet) my “LED driver” is bad. I'm able to pinpoint my tcon board

ANSWERS:

@serenderpity your LED driver is part of the power board. Check connector CON3 on your board. That is the one that has the wiring for your LED backlights. So, in the case of your TV it is possible that this is a bad power board or a bad LED arrays.
