    Did you check those solder joints? need steady feedback or this may take weeks, lol.

      Do a basic check of your diodes and resistors on top of the powerboard.

        Well, where will the backlight come from? For the backlight to work, the motherboard must give a command to the inverter "INV_ON"...
        How did you short the 1st and 7th pins, with the cable that goes to the motherboard disconnected?

            I checked the joints and they looked good.

            Will check the resistors and diodes later today, working right now.....
