MEB thanks for the schematic!

My 2007WFB rev a00 had Q2 populated as well.

Q2 is 5V output and its switched on via a signal from the cpu.
It is used to power the LCD and it goes straight trough pins 9-10 to the Logic board and straight to the LCD harness plug. Q2 is driven by the 2OUT of U3 TL1451A via a signal line through the connector to the logic board, i forget which one.

When the monitor goes to sleep the 5V is shut down so if you test that board out of circuit...
