    Samsung UE40F6270 BLU ON/OFF missing

    Hello....

    i have an samsung tv that not turn on..
    the problem is a missing (i think) BLU ON voltage.

    when i start the tv with diconnecting cable (mainboard - power supply) the backlight turns on so i mean the backlight is ok.

    do anyone have an service manual or an idea where i can search for the error...
    mainbaord: BN94-06715F (BN41-01958B)

    i'm happy for any help.

    best regards
