Fred is correct.
Looks to me like you have some serious moisture problems in the ccd chamber. Bake as per instruction manual. (Add salt to taste.

)
It also takes a freshly baked dessicant plug a few hours to suck up the moisture from the chamber. This process can be hastened by also purging the chamber with dry nitrogen.
