In repairing mobile phones  this is very helpful on how to easily determine on how or of which spare parts will come to check first before proceeding to other test and check up methods.
 All you need to do is to determine or identify the mobile phones assembly of components that correspond with the flex cable connections.  In most cases flex cable have highly risk of being easily damaged on clampshell and slide phones.
A damaged Flex cable can be easily determine visually and some others will not, there are flex cables that are shaded and coated with black adhesive.
 

Repair Tips: Make sure to have as much or more replacement flex cable stock on your shop to a certain mobile phones that are mostly used in your areas,  for quick and easy test and  check up procedures. All you need to do is just replace the suspected damaged flex with a good and working or a new one.
