7D body technical error - takes only half exposed shot - no video

[numra]

I'm having a weird problem with my 7D - a technical error telling me to turn my camera on and off and to reinstall my battery is coming up. It isn't allowing me to shoot video. It is also only half 'exposing' my shots - that is, only half the image comes up - the other half of the shot is black.
Does anyone know what this means? It happened all of a sudden when I wasn't having any problems prior - it is aproblem with the shutter?

Yep, the shutter is probably fried if you are getting only half images. BTW, what is the error message you are getting?
