i have this problem that i guess will require technicians, but maybe there is still some way to fix it easily.
so i have this MacBook 13", and yesterday came out this problem: everytime i leave or turn off the computer, the screen illumination turns off (i see that computer works normaly, just the screen brightness is like reduced to 0), if i use F2 i see just a little fash (1/2sec), to get it back normal i need to play with F1&F2 for a while (~15 minutes) turn some movie, to heat the screen i guess, then little by little illuminations starts to be on. tho again if i leave computer for few minutes without any movie on, happens the same.
does anyone know what might have happened?
