Bizarre Preview/Photoshop distortion on pictures

[f-matic]

Hi there,

I'm trying to fix a friend's laptop (PB 12" G4) which has developed a bizarre problem where pictures in Preview and Photoshop display yellow patterns on top of the image. The pic below is a screenshot of a sample image. The particular yellow artifacts change if you zoom in or out, but if you save from Photoshop the yellow artifacts are saved onto the image itself!

Also, and I'm guessing this is related: when you open Photoshop, you get an error message saying that the "monitor profile is defective" and recommending that you either calibrate or create a new profile. I've tried both but not matter what it displays the same message at startup.

Can anyone help? I've never seen anything like this before. I've tried all the usual repairing permissions junk to no avail. And this problem started a week or so ago apparently, in 10.4.0, but applying the updates to 10.4.3 did nothing.

Any help would be much appreciated!

Nick

Try using Profile First Aid in the ColorSync Utility application. Also, perhaps delete the preferences for Photoshop and Preview.

i don't think it's the monitor problem. i think that photoshop is screwed up. try deleting the preferences for adobe (they are in .plist extention files)and if that dosen't work, uninstal and reinstal, while deleting not only the application folders themselves, but their preferences and caches as well.

if that dosen't work, your Mac OS is screwed.

Thanks for all the suggestions so far, but I'm afraid none of them have worked -- I've deleted all preferences relating to Preview and Adobe, using the Profile First Aid, and I'm still getting the distortion. Any other ideas?

All suggestions are much appreciated!

Where are the images created? Have you confirmed this problem is only on his Mac with these two applications? Perhaps there is something wrong with the image capture itself...
