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?
Thanks
Ist dies eine gute Frage?
