See the thread on changing the bulbs. (You can change the bulbs as well!) There are some multi-connectors behind the display which may need a jiggle and some wd40. If a 'slap' on top of the display solves the problem, then it is this simple old-connector-corroded-or-loose problem. (A 'slap' is probably not recommended by Citroen, but definitely required for the person who designs the idiological bits of modern cars.!)
