Has anyone had experience with a Samsung UE49MU6170UXZG that will not power up?
No standby led, no sound, blank screen - dead.When you disconnect the system board backlight is running.
Motherboard:BN94-1239C
Powerboard:L55S6R MHS BN44-00807F

If "backlight is running with mainboard disconnected" means the backlight stays on, then suspect mainboard as the problem.

Main board failure like nomoresonys said. Look for a replacement main board, unless you are willing to try your skills to change the main IC.
