Power PC G4, running 10.4.11. Everything works fine, but the monitor has started the repeating sequence of 3 short flashes. Any way to fix this without re-installing?

Hi Mitch,


If one of the Apple LCD displays detects an error condition, the power LED will flash in a certain pattern to indicate the issue.

Verify that your equipment is compatible and restart the computer. If the issue continues, reset the PRAM.

Make sure you are using the correct power adapter with the display. This alert will only appear on displays built in 2004 or later which require an external power adapter.

The display is detecting a backlight error. Check your display's power connections and restart the computer. If the problem continues, contact Apple or an Apple Authorized Service Provider.
