The pictures are not focused for us to read the lable on the connectors, please provide better pictures of the top side and the bottom side of the board, thanks.
Monitor model number? Brand?

So you do not have any DC Voltage on any one of the pins on the white connector that goes to the LOGIC/MAIN board?
Pictures are still not focused.

OK then, take the DC Voltage readings of all the pin using chassis as the Ground ref point and report the readings.
