    Samsung led tv UN60J6200AFXZA went black no power no standby light

    PLEASE BARE WITH FOR I DONT KNOW MUCH ABOUT FIXING ELECTRONICS. I scrap electronics for the pm so have a little knowledge on it. I have a samsung tv model # UN60J6200AFXZA version EA03. It completely turned off and would not turn back on. No standby light. I'm looking on replacing the board/boards or led back lights. But I'm not sure if it's the power board or the led back lights. I tested the fuse it's good. I then tested the pins on the power board connecting to the led plug. 9 pins 1,2 D+ 3NC 4S- 5NC 6S+ 7NC 8,9 D-. 1,2 had good reading 6 showed good reading. I then unplugged the power and the led plug from the power board then retested same pins. 1,2 showed good reading 6 showed 0. So now I'm not sure my next step. Did I test it correctly? I dont have money to buy a new tv so im looking for any help anyone can give me. Me and the family would really appreciate it thank you

    What do you mean by good readings, What are the readings?
    What are the Voltage readings of the power supply connector that goes to the main board?
    Also attach the pictures of the whole backside of the TV showing all the boards.
    What is the power supply model number, BN44 -XXXXX? Your picture is too blur to reading anything on the board.

      With tv unplugged from power, unhook cable from powerboard to mainboard, leave it off, plug power cord back into powerboard, do backlights come on and stay on?

        At this point you have to figure out what board your trouble is. What you are describing, could be the PSU or the main board. If the lights come on like in the test from post #3, I would verify that stby power goes into the main board. If stby power goes int the main board, but no little stby led, your main board failed.
