How to Exit the Factory mode
Use one of the following methods:
• Select EXIT_FACTORY from the menu and press the “OK”
button.
Note: When the TV is switched “off” by a power interrupt, or
normal switch to “stand-by” while in the factory mode, the TV
will show up in “normal operation mode” as soon as the power
is supplied again. The error buffer will not be cleared.
5.2.5 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: “123654” (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!
