Hello guys,

a friend of mine has an Acer Nitro 5 AN515-51 with a faulty backlight - it turns on and I can see the Acer logo if I put a light behind the panel.

There was a shorted capacitor on one of the rails of the NCP81205A PMIC which I removed but didn't improve the situation anyhow.

I've measured the eDP cable and there is no connection between the last 4 pins where BL_PWR should be.

Do you have any idea if the panel has an integrated backlight controller or how should I proceed with the repair?
