This happen to my IMac (3 short beeps, 3 long beeps etc) Apple wanted $500 to replace the logic board I swap the pram battery and the iMac booted like a chame
Before I replace the video card: when I turn on imac, the apple logo comes up. Then the screen goes to orange, then pink. Also i thinking about getting the video card fixed
I taken the laptop to Apple Genius and told them it wasnt the logic board They came to the conclusion (which I knew) it was the logic board and wanted $315 to fix it
Hi Dont trust Apple Genius. If I paid them to replace the LCD then I would had the same problem I have replace the screen and inverter; had a spare data cable and it didn't work. I'm trying to get hold of an inverter/antenna cable to see if was that. Also when I press some part of the top left or right casing the screen goes back to normal Gonna check the top casing to see if there a short too ;-)
