We are working on this tv (Samsung UA60D8000) currently, and noticed we couldn't force the backlight on. Since the power supply is just clicking we were trying to isolate the problem, and found even when we forced the back light the capacitors never really charged going to the leds. We replaced the FETs at Q9201. It worked perfect !!!

Thanks stjeff0, the TV is not with me any longer but I assume the FETs are on the power supply board?, if so, I had replaced the power supply board and in my case it did not fix the issue.
