I have a Macbook (White 13-inch Late 2006 Model) I power this bad boy up and all I see are pastel vertical lines on the screen. I'm hoping this can be an easy to moderate fix. I pray that I don't have to purchase a new logic board because I purchased this laptop off of ebay and it cost me alot already. So I'd be in forever in anyone and everyone's debt who can help me to the best of their abilities. Please Any Help Appreciated!!!!!!!!!
