Customer Service Mode (CSM)
Purpose
The Customer Service Mode shows error codes and
information on the TV’s operation settings.The call centre can
instruct the customer (by telephone) to enter CSM in order to
identify the status of the set.This helps the call centre to
diagnose problems and failures in the TV set before making a
service call.
The CSM is a read-only mode; therefore, modifications are not
possible in this mode.

initialized after corruption, this set type has to be re-written
to NVM.

replaced or is initialized after corruption, this production
code has to be re-written to NVM.
