Got a Mac air of which the trackpad is frozen. Keyboard works. I changed the trackpad, same result. Measuring pin 10 of the trackpad connector it showed 0.5-1V not 3.3. After removing the board and no trackpad connected, its 3.3v. R4830 os 0 ohms as it should be. Any ideas?

On a sidenote, there was a tiny liquid spil on C7555 near U7201 which after i replaced the IC and made a wire the mac worked again. Customer had issues with trackpad before the mac died. No liquid on cable.trackpad looks very clean.

Found out the 5V was also missing, related to the C7555, the line to L4820 was broken, so I pulled a wire from L4820 to C7555 and working again, thanks for the help guys.
