Re: Macbook Air, no backlight 820-3024

thank you for the help. I think I should view these signals with an oscilloscope, because the mean value measured with a multimeter is not useful, right?

Hello everybody, this is my first post of this very interesting forum. I hope I can give my help if I can.

I am having a problem with Macbook air, board 820-3024: there is no backlight.
I measured some voltages and found the following:
PPBUS_SW_LCDBKLT_PWR = 8V
PPBUS_SW_LCDBKLT_PWR_SW = 7.8V
PPVOUT_SW_LCDBKLT = 7.6V (I think it should be more high)

I tested:
D9701 seems OK
C 9796 seems OK
C 9797 seems OK
C 9799 seems OK
L9701 seems OK
F9700 seems OK

at this point I suppose it could...
