The Macbook turn on, I have CHIME sound, I have a normal fan spin. I have the Lcd attached to the Motherboard...
I have these readings:
F9700: 12V
Q9706:
PPBUS_S0_LCDBKLT_FUSED=12v
LCDBKLT_EN_DIV=12 V
PPBUS_SW_LCDBKLT_PWR = 0v
DDC Circuit:
u9000: LCD_BKLT_EN = 0v (I understand that you're only present when
you recognize the Lcd)
PP3V3_S5_LCD = 3.3V
PP3V3_SW_LCD = 0v
PM_ALL_GPU_PGOOD = 3.33v
I understand LCD_BKLT_EN It's generated in U9600 (PB7A).
I have these readings in U9600
PP3V3_S0_GMUX =3.3 v
PP1V2_S0_GMUX= 1.2v
PP1V8_S0_GMUX =1.8v
PP3V3_S0_GMUX = 3.3 v
PP3V3_S0_GMUX_LRC_VCCPLL = 3.3v
EG_PWRSEQ_EN = 3.3 v
GMUX_DEBUG_RESET_L = 3.3V
My questions:
-What are the voltages to be measurable to ensure that the u9600 is alive?
-am I going well in my busage sequence for the fault?
-what is your recommendation as an expert?
Thank you for your time
