1D Mark 4 issue

Hi there,

My 1D Mark 4 have some patterns appeared on the picture suddenly. They looked like morie. Does any one have the same issue as the picture I upload.

I tried to reset the custom functions to default. I also took out the battery for a couple of hours as well. The camera still produce that kind of patterns. It seems that the patterns shown up most at the low light area.

This is the main camera that I supposed to use for a business seminar at Switzerland. What a bad luck !

Due to the time difference from Hong Kong, I wish I have time to contact Canon Hong Kong, or Canon here.
