Any thoughts on the cause of the pink strip across the top of the photo. Reformatting didn't solve it. Haven't tried a different CF yet.

Hmmm... Does this happen on all shots? I am assuming so since you said that reformatting the card didn't fix it. I doubt this is a card issue. I hope I am wrong, but that looks like it might be a light leak/shutter problem.

Though I haven't seen this issue before personally, it looks like a shutter bounce, where the trailing shutter blade has bounced when it finished it's travel. Were you shooting high shutter speed? Does it go away if you shoot a low shutter speed? If so, it probably means a shutter tune up, which I understand from camera repair people isn't that big of a deal, though you will be without your camera for a while...

I guess I should have explained in the original post that this is happening in all pictures and that this is a P&S (not mine). My guess is that this is happening regardless of shutter speed, aperture, etc, because most likely the camera is placed in Auto and never changed. So, depending on shooting conditions, both shutter speed and aperture are changing.

My guess is sensor, but I thought others here might have ideas. Another reason I say sensor, is that the entire pictures seems to have the same magenta cast to it, like the WB is off.

looks like the shutter is a problem.
I had something similar on a 1Ds2 which was worse when sold. Had to have shutter replaced. On a P&S the shutter is probably simulated, and therefore points to a dicky sensor.

no the shutter is not simulated on a point and shoot camera although the sound usually is simulated. i feel the cause is with the imaging processor. it appears to be truncated on the very first few lines of the image. unfortunately its not something that can be solved save for trying to update the firm ware. the reason i dont beleive its the shutter is cuz typicly shutter systems run diagonally across the image not perfectly horizontally.

ahh...

(I am a little ignorant of the P&S genre.)

The fact that there's some info there, but it's kind of warped and skewed (and missing some colour - I think blue, pecause it's pink), indicates to me that the sensor is PROBABLY OK, but that the communication from the sensor to the processor is not working right [or some such].

If it's in warranty it should be covered (unless it looks like it's been run over of course). If it's out of warranty, probably not worth repairing - but if you can get a "free quote", it may be worth having it checked over.
