Powerbook Vertical Lines Screen Problem

Hey,

Well it's my first post here and unfortunately it's a problem with my 15 inch Powerbook

I came down to start work this morning and was greeted by this:

As you can see, it was a bit scary. So I rebooted in a panic and luckily it booted back onto the desktop. But then I noticed faint white vertical lines alll over the screen - rather like venetian blinds (the white is a few pixels wide and then a chunk of dark and so on).

A search of the internet led me to update to 10.4.8, zap my PRAM, fiddle with the display settings and change resolutions. Hmm no joy.

Then the coloured lines happened again on a start up. I rebooted and they went, but still the faint white lines.

Has anyone got a clue what's going on here? And why's it suddenly started happening? I had 10.4.7 installed for a good few months with no issues at all and seeing as though the 10.4.8 update hasn't solved anything it can't be that. I haven't dropped the laptop or anything. I really am worried here, as I do all my work on the Powerbook.

Any help massively appreciated...

 

Hey, thanks for the reply!

Well without taking my powerbook apart, I can't see anything. I've given things a good old waggle to see if there's anything loose and no joy.

Logic board? Blimey. That sounds devastating. Are there any tests or anything you know of that I can run to confirm this?
