UPDATE: Bugger, the Samsung is on the blink again.
This time I think the backlight inverter is rooted, or the 24v from the power supply has stopped for some reason.
TV powers on OK, and has sound but a blank screen.
In a dark room with a light above the screen I can just make out images, so I guess the LCD drive board is OK.
I followed the steps in the below video to check the backlight inverter board, but I'm not getting any power to it.

The bottom cable from the power board isn't sending any juice to the backlight inverter during or after start up.
The top cable is listed as 12v, but is doing about 11.5v
Any ideas all you smart nerds out there?
