I had exactly the same problem with my 5DMk2 after having the CPU board replaced.
It is not banding but rather some artefacts that can be adjusted.
After having the camera adjusted there is no trace of those vertical bands anymore. I\'m not sure what they adjusted though, it only says Readjustment of CMOS and whitebalance on the service sheet.
That implies that the artefacts/bands are not within specifications, and that when a certain body suffers from this, it is malfunctioning. Good to know it seems correctable.
I am curious, do you have a sample containing the artefacts/banding from your 5D2 before it was fixed?
