Check the voltage to ground of each inductor.

Each inductor is linked to a local buck switching power supply. If the inductor shows a low or zero voltage, that power rail may be defective.

Re: asus g750jm black screen

Personally do not have a schematic for this logic board.

Being an Asus model, the schematics are rare.

For checking the inductorys, no schematic is required.

Post a clear pic of the logic board and we can point to them on the board to get you started.
