flickering monitor iMac early 2006
I would like to have your help about a problem I’m having with my old imac:
very often when I turn on my imac the screen has these colors (I made a video with EyeTV on for maximum effect).
most of the time, just put on sleep mode the monitor and the screen returns to normal.
Sometimes the opposite happens :at start up all its fine,but if the monitor get in sleep mode the problem come back.
I have a Apple iMac "Core Duo" 2.0 20-Inch model a1174 (no emc on the “foot” )
The front panel has allready been replaced (problem of vertical lines,always after sleep or screen saver ) years ago,but instead of the vertical lines i had this new issue !
I know its an old mac,but I would like to understand what its happening.
Thx for the help and sorry if I made mistakes,English its not my language!
Is this a good question?
