Help-any ideas before it goes back to Canon

I was shooting a music festival this afternoon and just happened to take a minute to review my shots. Blank screen!
I have attached 2 photos. One of the last photo that registered, and one of what everything afterward looks like.

I have changed cards, changed lenses, changed modes and shutter speeds. Took the lens off to see if the shutter was hung up and it is working. I removed the battery and tried another one. I'm thinking the prognosis is ugly, but I wanted to see if anyone has ever had this problem.
Of course I'm hoping I have overlooked something, but I can't imagine what.
Any ideas out there? Thanks.

Doesn't look like a shutter problem because the line between the picture and the black is very sharp. It'd be blurred if the shutter were hanging up.

So it looks like a data problem - quite possibly a bad CF card.

We've seen similar problems attributed to card readers, but if you see them that way in the camera that's not it.

How about formatting your CF card? Trying another?

-js

you try formatting the card inside the camera instead of from the computer?

I've tried several cards this afternoon, and they are always formatted in the camera. Thanks, anyone else have an idea?

My first thought on seeing the images was a CF card fault, but I don't think it can be. You've tried multiple cards and the pattern is not typical of jpeg corruption, and is identical in the two images. Shutter failure doesn't fit either.

I think you have a camera fault, and I'd guess it's in the sensor electronics.

Edit:
Just MAYBE, death rays from mars have upset your processor, so try a full reset - take out both batteries (including the date/time button battery) for a minute, put them back in, and try again.
BTW: What body is this?
P.P.S. Ah - 20D - got it from the EXIF.

I was thinking of reinstalling the firmware. Do you think that might have any effect?

Interesting thought. For that to work would mean that the firmware had become corrupted somehow (death rays from mars), but not irreversibly, i.e. the data/code contained was subtly corrupted, but the hardware was still perfect.
It seem unlikely, but it's sure worth trying on a "nothing to lose" basis.

Are you using flash ?

Looks like the cmos died.
