5.2.4 Customer Service Mode (CSM)
Purpose
The Customer Service Mode shows error codes and
information on the TV's operation settings. A call centre can
instruct the customer (by telephone) to enter CSM in order to
identify the status of the set. This helps them to diagnose
problems and failures in the TV before making a service call.
The CSM is a read-only mode; therefore, modifications are not
possible in this mode.
Specifications
• Ignore "Service unfriendly modes".
• Line number for every line (to make CSM language
independent).
• Set the screen mode to full screen (all contents on screen
are viewable).
• After leaving the Customer Service Mode, the original
settings are restored.
• Possibility to use "CH+" or "CH-" for channel surfing, or
enter the specific channel number on the RC.
How to Activate
To activate CSM, press the following key sequence on the
remote control transmitter: "123654" (do not allow the display
to time out between entries while keying the sequence).
Upon entering the Customer Service Mode, the following
screen will appear:
