i have the early 2010 iMac 27' i7, i noticed a few problems with it since i have bought it. i going to do a trip to apple store after xmas just hadn't had the time to take it back yet since needed it for work stuff.
I noticed sometimes few times a day i doing something on the imac and the screen dims its self for split second is the the flicker issue? i know i have the high pitch sound caused by the brightness setting which i need to get fixed and i think its the power supply when the imac gets quite hot its starts to make a grinding type noise but turns off if i turn brightness to maximum.
just curious about the split second dimming issue this is my 2nd imac first one had to take back because had huge mark on the screen.
Thanks
