Bernie, post an image of your logic board test points. You are definitely having issues with it since you are missing some voltages:
 
Test Point Functions:
*
*
Pin 11: Ground
* Pin 33: 5V power for Hard Drive(s). Note: If present, the 12V power will come directly from the Power Supply to the Hard Drive thru the power harness cable.
* Pin 44: Standby 12V power (permanent power coming from power supply, present as long as AC cable is connected, even if computer is off); '''corresponds to LED #1'''
* Pin 66: Backlight Control pulse width modulated signal (from logic board to LED backlight board, to adjust the backlight level setting according to user setup)
* Pin 1111: 12V Run-Mode power to logic board (coming from power supply, present as long as system is on or asleep); corresponds to LED #2
* Pin12Pin12: Power On Request signal (from logic board to power supply when power button is pressed)
* Pin 1313: Backlight Enable (signal from logic board to Backlight Controller board, to enable backlight"
* Pin 44: is about the only one that is correct.
