Hi,
This I/O board for Macbook Air is powering the board properly, but no green or orange light appears. Is there any schematic available for it? I cannot find one on internet. Or any clue what to look at?

Thank you for the schematic.
Sound is present, indeed a trace was broken on a test point for PP3V42_G3H_ONEWIRE
Nice repair! thanks
