Fuzzy display on startup - iMac 20" early 2009
During installation of a new superdrive, I unplugged the 4 inverter cables from the display, once all put back together and on startup I get a fuzzy screen (like bad terrestrial tv signal). Once the mac has started up i can put it to sleep then wake again and the screen is back to normal. Could this be the inverter? why is it ok after sleep?
Is this a good question?
