Won’t turn on

Hi, I have a CitiZ and it’s not turning on. Which internal component is likely to be causing the problem? I have an old Magimix I could use some of those parts. Any help would be appreciated. Thank you. Hi, I have a CitiZ and it’s not turning on. Which internal component is likely to be causing the problem? I have an old Magimix I could use some of those parts.
