Hi Peter,

If you rub (put slight pressure) on your screen with the cleaning cloth that 
came with the MBP do they disappear?
Has the MBP had a knock or a drop?

Vertical lines appearing are related to the screen or the GPU or maybe even 
simply a faulty ribbon cable.

You would need to get a Technician to look at it if it persists as you might 
need the LCD Panel replaced.
But being a 2007 machine, the cost of screen replacement might induce you to 
upgrade to a new MBP.

Cheers,
Ronni
