PDF | Lines Across Macbook Screen Document
My husband bought me a second hand iPhone 4. Some MacBook owners have reported an issue where a distorted screen appears during startup, characterized by a series of vertical, multi-colored lines. When we last wrote about the problems with the new 27-inch iMac's screen a few weeks ago, there were over 1,600 replies on Apple's support board about the issue.

I am facing this issue in my Macbook for past one week where it just shows up some multi-coloured lines in middle of the screen and won't go at all. About a month ago a pink vertical line appeared on the screen. Last week he installed iOS 7 and the phone now has flickering horizontal lines across the screen, rather like interference on old televisions. Apple has released a new graphics firmware update for its new MacBook Pro 17-inch laptops, addressing the issue of vertical lines appearing on the display. Foreign material that is trapped within the screen must be removed by an Apple Authorized Service Provider or Apple Retail Store. Your Mac initializes its BootROM and memory (RAM).
