Is there a way to tell if the LED driver circuits are working properly ?
It's a Samsung UN46D7000 which works (when it's not rebooting) because the bottom quarter of the screen is darker than the rest of the panel. Of course I suspect bad led(s) but would like to be prudent before cracking this thing open.
So what measurements and how to take them ?
