Customer Service Mode (CSM)

Purpose
When a customer is having problems with his TV-set, he can
call his dealer. The service technician can than ask the
customer to activate the CSM, in order to identify the status
of the set. Now, the service technician can judge the
severness of the complaint. In a lot of cases he can advise
the customer how to solve the problem, or he can decide if it
is necessary to visit the customer.
The CSM is a read only mode, therefore modifications in this
mode are not possible.
How to enter
The CSM will be turned on after pressing the MUTE key on
the remote control transmitter and any of the control buttons
on the TV for at least 4 seconds simultaneously. This
activation only works if there is no menu on the screen.
After switching ON the Customer Service Mode, the following
screen will appear:
