iMac 27 Inch make buzzing noise
Hi,
I have an iMac 27 inch (late 2012) and since a few hours the screen (i think) makes a buzzing noise depending on the color on the screen. (full screen)
Red: makes a buzzing noise
Green: makes a buzzing noise
Blue: makes a buzzing noise
White: no noise
Also when I make the display brighter or darker i hear the sound.
Using os x Yosemite 10.10.5
Does anyone has an idea to fix this?
Regards,
Denny!
