Q: Does anyone else have streaks on their MacBook Pro display after 10.6.8 update?
It's as if the LED backlighting is not turned on for columns of the screen. The top is lit normally, but at the bottom of the screen, extending up from the dock, there are dark and light sections.

It was a problem that many 4,1 MBPs had since the beginning.

Mine didn't show itself until a year later. It happens intermittently, but often it happens when I update OSX. Somtimes after rebooting to Boot Camp. Usually zapping the PRAM will fix for me. (Temporarily, obviously.) But I've lived with this for the past two years, even having two repairs and still it'll happen. (Fortunately I had Applecare, for the repairs, but that just ran out.)
(edit: Apple had known about and "fixed" this back in 10.5.3, which I remember applying for this specific reason:

But it seems like each new OSX update "breaks" it again. )
