What pin was connected to that inductor?

Re: Toshiba P50-A-14H-PSPMHE VGSG_GS MB REV.2.1

it was the pin1 should be 19v.
without lcd panel it has 19v. but when we connect the lcd panel there is 12 v. The value of the inductor measured as 2.1 kohm should be 0 ohm.when changed inductor problem solved.

Only the supply went down?
