A guess as i've not seen this, but it sounds as if the sensor array has partially failed for it not to read large chunks of exposure information.
The half black screen did initially sound like maybe the upper half of the shutter mechanism is jammed/stuck.

They may have they been exposed to damp?

For the one that's partially black. i might try a code update if its available just in-case this causes the unit to refresh its behaviour - but this is a real long shot.

Hi on the 1000D try putting it in live view mode or mirror lock up and see if the image is taken ok. It could be you are seeing a mirror failure (where the secondary mirror does not move out of the way) or it could be a shutter failure. Try putting the camera into cleaning mode, can you see all of the sensor when the lens is off. I am afraid if it is what I think then you are looking at an @ £130 repair, that may well put them beyond economic repair. If it is like the old 300D and it is the secondary mirror pivot that has failed then there is a web documented repair of the pin using a piece of wire.

Is it a transition from image to black or is it only half an image? Could be electronics failure.

For the 450D I would do the cleaning process and look for visible contamination/problems. If none then I would suspect sensor/electronics failure.
