Do not worrying about 44mV potential diff (you will always have resistance between point A and Point B for Voltage to be developed, beside, 44mV is way too low to affect logic level), concentrate on as to why you are not getting 12VDC to the T-CON by checking Voltage on that Q14 pins base on data sheet so you can see which pin is the feeding pin., it is more likely to be P-Channel MOSFET, so the 12V should be fed to the Source pin may be via some kind of inductor.
