Hi I have a Macbook 12 inch with no display external and internal also tried a good working display. The machine is turning on as all powerstates are there including S0 and cpu gets warm and has power. Display is missing backlight power as well as 5V, 3.3v is present. Q7706 has 8.6v on pin 3/4 and on the otherside once i got 8.6 and mostly 0.44v. For PP5V_S0SW_LCD, which is 0v, as well as U7701 the enable signals are 0v. Any idea how to troubleshoot this piece of junk ?
