CN301 Powered Off:all are 0.00v except pins 2,7,8,9 these are 0.05v
CN302 Powered on Powered off
CN303 powered on Powered off
I know pins 1 on CN303, 1 on CN302, & 7 on NC302 are all low voltage or 0volts which control the backlight circuits. My question is do these voltages come from the power supply or are they returned to the power supply board from the main or A board?
Any help would be greatly appreciated. I have ordered a power supply but wanted some others opinions as well.
