   Look at the ribbon cable carefully with magnification.  The problems with   
   these is not that the cable gets loose but that there are small cracks in the   
   cable itself.   
   It is possible that there is a problem with the board as well.  Look for small   
   SMD caps that may have leaked in the area.  These too can cause problems of   
   various types in cameras of that age.
