Canon 580 II flash problem

Before I send it in for repairs I just what to see if anyone has had this issue and if I did something to the setting to cause the issue.

My Canon 580 II flash is set to full Ettl but only performs a pre-flash 1D IV no exposure in the picture.

It works fine on manual but when flashes in flashes first but then no flash in the picture.

This problem started yesterday it was over exposing all the shots (almost completely white) then it just seems to only use the pre-flash .

I checked all the C.FN and they are set to 0.

I have tried on two different camera bodies 1D III and 1D IV.

In testing with the second camera 1D II I did notice A few times it went into TTL and over exposed the picture. And sometimes the camera did not recognize the flash at all.

Anyone ever had this type of problem?
