On the cord where the flash mounts, is the plate with the contacts. By taking a very small flat tipped screwdriver, at the front you can carefully lift the plate up and slide it off. Under the plate are tiny screws that you can tighten. I have had this problem with my canon cord, and it is fixable. I have since purchased an after market cord and never had the problem since. I think Canon has a quality control issue here. Good luck.
Thanks for the tip. Thinking back, the cords that went south on me were all genuine Canon. Can't remember having a problem with the knockoffs.
