damaged ccd or?

[Albert09]

Hello
I am new on this forum and i have a question.
The images coming out of my Olympus E1 have a strange vertical line on every picture.
I have taken some picture without lens and they show the same result. The line gets more visible when i increase the iso settings.
Here is a sample picture taken @ iso 800 without lens:

So I am wondering what this can be, damaged ccd or light leak?

Thanks in advance!
