Monitor boots up in "DIM" state

huzz · 11-09-2004, 11:36 AM

Hi,

I have a G4 eMAC 1Ghz OS X v10.2.8.

When our MAC is first booted, the screen isn't bright like normal. It is in a dark dim state, similar to standby mode when left idling. The only way to make it bright again is when we put the MAC to sleep mode, and then reactivate the screen (ie return from sleep mode). Once the screen brightens up and return from sleep mode, the mouse arrow would freeze for a few secounds before it could move again. Also, if the computer is left idling, it will go into the "dim mode" again.

Is this a hardware or software problem that can be fixed with disk utility? But we already tried rebuilding the desktop with Disk Warrior 3.0.2 with no result. Does optimizing the HD help? But we could not find that function in Diskwarrior 3.0.2. Thanks for your support.

and try the PRAM reset as recommended there.

Hey,

Someone also gave me another suggestion about the "DIM" monitor as follows:

"Hmmm... looks like the return of the evil AVB to me. AVB (Analog Video Board) was a particularly failure-prone part in CRT iMacs. On its way out, it causes all sorts of strange behavior, including the one you are experiencing. It looks like the eMac inherited something from its older CRT sister... It will be replaced under AppleCare if the behavior is easy to reproduce."

What do you think of his suggestion? Again, thank you for help.
