Some month ago i bought a used iMac 21.5 Mid 2011. And since then there have been coming some wierd pixel flickering on my display. It's not dead/stuck pixels, they disapear and then a second after they comeback, etc.

I have had it to rep. at Humac and they have changed the Logic Board and the Display.

But i still have the issue, much more than before i send it to Humac!



I have also recorded a video of it:


Please watch it to the end!

iMac, OS X Mountain Lion (10.8.4)
