Post diode mode there first; w/ and w/o LCD connected.
Also need voltages for Q9706/07.

Thanks mate. As i was about to take the the voltages i think i found the problem. Corroded probe point on ppbus_s0_lcdbklt_fused.
R9788 Pin 1 0v but the backlight fuse has 12.6v on both sides.

Thanks for guiding me in the right direction, I ran a wire and it now has a backlight cheers mate
