obligatory obscure reference

Wondering if this has happened to anyone else….

I applied the most recent Apple Security Update on a PowerBook G4 15″, and after reboot, there’s a pixel-wide vertical stripe on the display. I’ve tried resetting the PRAM, rebooting, booting from install discs, booting into 9.2, letting it cool off, etc. Nothing has made it go away.

I guess it could be a coincidence, but someone else had the same thing happen and posted about it on the Apple discussion forum. I can understand a software upgrade triggering a disk failure by trying to use parts of a hard drive that are damaged, but how could it manage to trash a graphics adapter or display?
