Wtf Is Wrong With My Screen???????? Please Help Me.

try restarting first.

Press Command Option P R at start up right after you hear the start up chime/before the apple logo appears release when it chimes again and restarts.

if that doesnt work, remove the battery and unplug the system. press & hold the power button for about 10 seconds.

place the battery back in, boot up the system.

run the apple hardware test provided with your system discs to see if it shows anything out of whack if the lines appear again.

not 100% sure unless you can post a possible image of the lines youre seeing

 

previous happenings suggest it's a hardware problem, bet bet would be to take it back to your local apple store and have them look at it, they should be able to fix it for free since your still in warranty

oh in future, dont double post less then 10 minutes after posting a thread , every thread gets answered eventually
