i have a power mac g4 m5183 that i inherited, as well as a m7649 monitor. when connected, the mac turns on but the monitor does not, I also don't see a button to turn on the mac monitor. how do i turn on the monitor.???

Sorry to complicate matters, but I think that monitor was called an Apple Studio Display, not Cinema. Spec sheet here:

Can't find the manual as yet.
Just read my own link....
"The unique, touch-sensitive power button on the front of the display controls the entire systempower on, sleep, and wake."
