This may have been posted earlier, so sorry is this is a repeat. I've had this PowerBook since the first 17" versions came out in early 2003 and it has worked wonderfully. It even came adrift on a bicycle one day (strap broke with a brand new sleeve bag) it skidded down the road and bashed into the curb... still kept working.... other than a couple of dents and a lid that never closed again quite so well, it has been a fab machine. Anyway, a few months ago the screen started occasionally going a green/blue tinge, almost like very fine stripes down the screen. A wriggle of the screen seemed to fix it, but it has now become quite bad, and stays like that for most of the time. I figure it must be the connection to the screen from the system, as when using the laptop for presentations (connected to a projector) all is good. So my question is, does anyone know a easy fix? I heard that the wiring is built in, and needs the screen replacing, which doesn't make sense given it's nearly 5 years old. Any ideas? Thanks!
