Hello, a few weeks ago i got my first mac, an 27 inch Imac (base 2011 model). I really like it, but a few days ago i noticed a white Pixel. I can only see it on black or dark coloured Backgrounds, and its not really a huge deal, but as the machine is new it does disturb me. I tried a Pixelfixer application with the color flashing for several hours, but it did not help. Is there a way to fix this by myself? I wanna avoid taking it to an applestore as it is my only computer right now. If i cannot fix it myself, will apple take care of it for free? Thanks alot.
