pin 23 and 24= 0v

motherboard out lap

your voltages are not correct
pin 1.2 should be 3.3V
pin 3 ok
pin 23 24 19V
pin 25 3.3V

find out Q3000 test the pin S D G (pin 1 2 3)
FOR PIN 23 & 24 find the PAD6000 test voltage that point you should get 19V
Upload a pic of the LVDS connector

Just extract it first, then drag and drop any file with extension .ASC (whatever you choose on folder TODs) on your favorite boardviewer software.
