Yes. Ur remedy is success for me. Three months back I got same trouble with my 7dm2. After three days, camera became dead . I repaired it from canon service center Dubai. Unfortunately next week it started to show error 06. I returned to canon services again. After 10 days I collected camera. But, next day it started error 06. I knew the fault.it’s cmos assembly must be replaced. It is not preferable for me. I cancelled auto sensor cleaning function with menu. Now canera ok and works flawless
