Hi Guys, I have a Mac Air 13" 820-3209 which has a green light, orange light, and a spinning fan, but no chime, not turning on. I have checked all main power rails from 8.6V to 1.05V and they all seem to be present, even the S0 versions. Any tips on what to check next. issue might be in some data line? I fixed quite a number of boards (thanks Louis!) but all of the had power or backlight issues. This one is making me sweat. Any tips welcome.
