Hello,
I have a iMac 27" medio 2011 and since a few months I sometimes get a sizzling,electrical noise from inside the iMac.
The sound is related to the brightness of the screen as well,when I lower it to 60% the sound is gone,when put to 100% it makes a really loud noise.
When scrolling the sounds is worse as well.
Anyone has a solution for this problem?
Regards,
David
iMac, Mac OS X (10.6.7), null
I'd suggest to contact Apple Support, but before doing so, you may try these steps:
OS X Lion: Reset your computer’s PRAM
Resetting the System Management Controller (SMC) on your Mac - Apple Support
Sizzling electrical noise
