Today I replaced in my iMac EMC 2390 my 3.5 HD for a samsung 850 EVO SSD. Now I have some white pixels turning on and off almost like snow, random. And some now and then there is a partial screen twitch horizontal. What did I do wrong, I follow the guild to the letter. Who can give me some advise? Kinds regards Vincent
I would double check the display cables. Did you damage one (or the connector on the logic board) or not fully insert it?
