Hi,
I have an A1278 820-3115-B with no backlight. It works, gives image on external monitor, and with a flashlight on the back, it shows image.
I don't understand this readings:
On F9700 I get 0V on the pad 1 and it seams that PPBUS_3GH is shorted
PPBUS_3GH = 0V 0 ohm and 0V on diode mode.
But everything seams to be working besides the backlight.
Already removed F9700 with same readings.
Can you help?
