Just took delivery of a BTO powerhouse.. all the bells and whistles. 17" 2.6, with HD screen etc.. BUT.. Take a look at what i have on the screen.. of course i took it to the genius bar today and nothing showed once i got there. I think its when the backlight warms up... Any opinions.. is this normal? Its basically white-ish and can only show on a black background.. but surely this isn't right? Its back to Mac.. I cant face another 3 week wait for a new machine but i think it may be the only way to go! Should i get a replacement screen or just order another BTO and swap the whole unit? Don't know if i wanna replace my invisible shield protectors though... all more expense!
