This same problem happened on my Early 2008 MBP, intermittently. Found this post on Apple support that shows how to reset the display to rid the symptom. Seems the fix is only temporary, but can be repeated as often as needed. http://support.apple.com/kb/TS1258 An in-depth post on Apple's Macbook Pro Community Forum under the heading "Strange vertical stripes" suggest it's a known problem which doesn't get resolved with replacing parts.
