button.

5.2.3 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.
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 is visible).
• 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 CSM
To activate CSM, press the following key sequence on a
standard remote control transmitter: from the "Menu/Home
screen" press "456987", directly followed by the "Back" button.
(do not allow the display to time out between entries while
keying the sequence). After entering the Customer Service
Mode, the following items are displayed.
Note: Activation of the CSM is only possible if there is no (user)
menu on the screen!
