Huawei P Smart 2019 LCD light ways

Hi guys.
I have one Huawei P Smart 2019 than hanve't light on LCD.
Ligth stop after release. With other LCD no work.
Both LCDs work on other phone.

I trace LCD flex to PCB and found light pins.
Pins K1,K2 and K3 are ok, with 600 om. But pin A1 is not ok, it's have 220 om.
A1 go to one coil (L), then in PCB.

To repair it I need schamatics or more traced info.
