How to Exit
Switch the set to STANDBY by pressing the mains button on
the remote control transmitter or the television set.
If you turn the television set “off” by removing the mains (i.e.,
unplugging the television) without using the mains button, the
television set will remain in SAM when mains is re-applied, and
the error buffer is not cleared.
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.
How to Enter
To enter 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:

Digital Customer Service Mode (DCSM)
Purpose
The Digital Customer Service Mode shows error codes and
information on the IBO Zapper module operation settings. The
call centre can instruct the customer to activate DCSM by
telephone and read off the information displayed. This helps
the call centre to diagnose problems and failures in the IBO
Zapper module before making a service call.
The DCSM is a read-only mode; therefore, modifications are
not possible in this mode.
How to Activate
To activate the DCSM, put the television in its digital mode (via
the A/D button on the remote control).
1.
Press the “Digital” Menu button on the remote control to
activate the digital user menu (“Setup”).
2.
Activate the “Information” sub menu ( via the “down” and
“right” cursor buttons).
3.
In the “Information” sub menu, press the following buttons
on the remote control to activate the DCSM:
