Clean board and I can see the apple logo, however, no BL.
Already replaced the U7700, but still. I do have the enable, nut 0V on the PPVOUT_S0_LCDBKLT.
W/ the screen Plugged:
U7700:
Pin 5-18 = 5V
PPVOUT_S0_LCDBKLT = 0V / Diode Mode 0.31
PPVOUT_S0_KBDBKLT = 5V
BKLT_EN_R = 3.2V
LCDBKLT_EN_L = 12.38V
Q7700
Pin4 = 12.56V
Pin 1-2-5-6 = 0.34V
Yes, i replaced the Q7700 Just in case, however, still.
The fuse is fine.
