[QUOTE="johnodd4, post: 1658426, member: 331386"] even a pram or smc reset wouldn't help you. Let me explain. if your macintosh screen resolution exceeds the screens max resolution you will only get a blank screen because the computer is trying to use a 42 inch screen settings on a non 42 inch screen. inorder to fix this you would have to do a complete reformat and reset of the o.s as well as making sure you select the internal screen by using the keyboard shortcut on the apple keyboard it's key f1 and f2 which control the screen brightness. followed by the o.s choosing the correct resolution.
