Laguna Radio/cd Cover Problem

Normally when I open the cover that conceals the radio and CD on my 53 plate Laguna it is held by some form of spring or damper. Recently something gave way and now it isnt in any sort of control, as if something has become detached. It flaps about in a loose state but still held at the sides by the two stays.Can anyone advise on how I can fix this or method to take cover off to investigate?
