Logic board had spillage around C6907 . L850 was burned so replaced it and U8500 as no PP5V_G3S_ALSCAM. Now getting PP5V_G3S_ALSCAM and present on J8500.
I have tried 2 different screen assemblies both webcam not present. I have also checked L8503 and L8502 both read .223 diode reading.
U8502 was replaced but still same.
Any help appreciated.

Hi yes continuity on both L8502/L8503 . These should read about .5 diode reading but they read .223 .
u8502 enable pin 11
Can I measure this with board out or does webcam need to be connected.

How to check ALS?

You should check enable signal with camera connected.
Get video cable extension from Aliexpress; cheap enough, need 2!

Direct flashlight to webcam and check if LCD and keyboard backlight react.
