no I don't know which pin controls the power, but I did test all of them and according the multimeter they're all working. I used the continuity tester where you get a constant beep if all is working... and each pin checked out OK
Edit: do you by any chance know what the OHM (resistance) value is suppose to be across each wire? I'm getting continuity, but maybe not enough continuity. Maybe there is a tiny brake in one of the wires that is allowing for continuity, but not enough of a connection exsists for proper amount of current to flow......if you catch my drift
If I can find out the proper OHM value, then I can check that against the actually Resistance reading on the wires
and if I'm getting something other than what the value is suppose to be, I'll try purchasing another VGA cable
Edit: uh, I think length of the VGA cable makes a difference in what the ohm value should be, I'll try to look around and just figure it out
