Hi guys, i got macbook air and it boots up ,,,i hear the chime boot, got white screenm the caps look key lights up green, the fan works, i can hear the hard drive spinning, if i press volume up i can hear sound, the keyboard lights up, but still white screen, no apple logo, nothing at all but white screen. i did sms reset and pram reset but no use, still the same before. i tried to boot into recovery,,,,no use. i tried boot into safe mode by pressing shift key after the boot chime....no use. i got the wgite screen. i powered it off,,,then powered normally, still white screen, after few seconds the screen went gray, if i press any key it comes back to the same white screen. i opened it and and unpluged the hard drive cable, then booted it up...but there is no chime, but still white screen.... Any ideas ??? thanks all.
