Dear All
i have a board for Macbook pro 13" A1279 mid 2009 k24 2.26 with missing PPBUS_S0_LCDBKLT_PWR.
Q9806 which i beleive is the driver of it, pins 3&4 have 12.6v but pins 1,2,5,6
which are the outputs i have nothing.
checking Q9806 for short it seems ok.
i used my power supply and i appiled 1.5v to see if enable pin on U9701 will enable and it's ok(1.5V)
the output of Q9806 on schematic says 12.6v. can i get this voltage from somewhere!
thanks
