Hey guys!
Hoping I can get some tips on where I'm going wrong with this one!
I have a Macbook 820-3476 here that has been dropped and has no backlight!
I'm stuck in general.
PP5V_S0_BKLT_D = 5V
LCDBKLT_EN_L = 12.6V
VIN_S0SW_LCDBKLT_R = 12.6V
PPVOUT_S0_LCDBKLT is at 0V which I know means there is a break in the circuit, however I'm unsure of where to start with this.
I've follow the circuit and have 12.6v all the way until I get to Q7700 where I only have 12.6V on pins 4 & 3
I know it's a P type mosfet but I'm lost to why it's not working.
Can someone help me with my understanding of this, and fill the knowledge gap.
Thanks, Max
