My iMac Late 2009 Display, flickering, dimming, and pixelated
Display has been flickering and dimming during startup for a while now, didn't really bother me, until I upgraded the hard drive to an SSD. Then the display started to become pixelated. I have already connected the iMac to an external monitor and the problem does not transfer to the external monitor. Attached is a picture how it currently looks. Not sure if the picture shows the extent of how pixelated and oversaturated the colors look. Any help will be greatly appreciated thanks.
