Restart went smoothly, but the Display's Power Button is Still FLASHING In A Series of repeating 3 flashes on, then off, then 3 on etc.

The flashing are very brite.

I NEVER Use the Display Power Button for any reason,
it's actually more difficult for me to access that
the G4's PowerButton ...and I usually Shut Down
using the Apple PullDown.

It's a Big OLD Lucite Easel Display 30" -- ?
