New iMac 27inch screen flickering/tearing/shutoff

I have been experiencing some problems with the all new iMac 27inch display.
At non-fixed intervals i will get one of the following:

Screen distortion/flicker somewhere random in the screen (feels like it is more in the lower part) that looks like a horizontal bar of about 2-3inches just popping in and out of the screen.

Screen will go completely black for a second and then come back on. Sometimes 2-3 times in a row.

Somebody else already made some video-clips about these problems, I am experiencing exactly the same behaviour.

Just to not that in the course of writing this post my screen has flickered 13 times and has gone black 2 times.

Hey Spurv2,

Appreciate you sharing that story about Apple Care WANTING to send you a third iMAC to make sure the problem is solved. I appreciate you sharing because I am going to purchase one as soon as they can resolve the yellow tint issue. Not sure you are surprised in a good way or frustrated way.

I have had problems with my keyboard and speakers when I bought my older iMAC. It floored me to reach customer service directly in a few rings of the phone, the guy spoke perfect English, was in a service center IN AMERICA, anticipated the problems I was having before I finished describing them, immediately said he would send a MAC PRO keyboard to replace the standard white model, would send a new set of HK speakers, and when I asked how to ship the defective ones back he said just keep them. My first thought was, "Am I in Customer Service Heaven?"

Keep in mind this was when companies like Dell and HP had quietly shipped all their customer service to INDIA and stripped their service policies bare.

For this kind of service I would have gladly paid more for the iMAC then and I paid $2400.00. After years of dealing with nightmares of other companies careless approach to customer service I will stay loyal to MAC as long as they care this much about the customer. It is the least discussed attribute as to why "MacHeads" are so loyal but my first reason...peace of mind and a product that just works. And if it doesn't they will fix the problem!! What other company works like this?
