Backlight issues after water damage on Logic Board
Hello,
I bought a faulty Macbook Pro A1708 - 2017 Function Keys model with the issue being the backlight not functioning for the display. I have a limited knowledge on circuit boards and wondering if anyone could shed some info on what I should be looking out for in terms of measuring voltage, resistance etc for the components and the necessary steps to check if all is working. I have the circuit diagrams and boardview to assist.
I have images below showing the damage on the board:

Thanks in advance!
Is dit een goede vraag?

So I managed to get the device working. All it needed was a clean however there are a few issues:
The iSight Camera doesn’t work. I open any app that uses the camera and the green light blinks and there is no image being shown.
Another problem is after resetting the SHC controller the Wifi temporarily stopped working - as in i was unable to enable it - it kept automatically disabling after i turned it on - Later resolved after checking the connections on the logic board (nothing was loose/unconnected) which was strange. Also, bizarrely this all was accompanied by the fan running at full RPM after I had reset the SHC controller. That’s fixed now but just mentioning it incase it has any significance relating to hardware.
Any help in finding the solution?
