5.2.3
Customer Service Mode (CSM)
Purpose
When a customer is having problems with his TV-set, he can
call his dealer or the Customer Helpdesk. The service
technician can then ask the customer to activate the CSM, in
order to identify the status of the set. Now, the service
technician can judge the severity of the complaint. In many
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.
When CSM is activated, the layer 1 error is displayed via
blinking LED. Only the latest error is displayed. (see also
section
5.5 Error
Codes).
When CSM is activated and there is a USB stick connected to
the TV, the software will dump the complete CSM content to the
USB stick. The file (Csm.txt) will be saved in the root of the USB
stick. This information can be handy if no information is
displayed.
Only for Q548.1:
When in the Q548.1 chassis CSM is activated, a test pattern
will be displayed during 5 s.: 1 s. blue, 1 s. green, and 1 s. red,
then again 1 s. blue and 1 s. green. This test pattern is
generated by the PNX5120.
So if this test pattern is shown, it could be determined that the
back end video chain (PNX5120, LVDS, and display) of the
SSB is working.
For LED backlight TV sets, the test pattern is build as follows:
1 s. blue, 1 s. green, 1 s. red (generated by the PNX5120) and
further on with 3 seconds RGB pattern from the LED Dimming
Panel.
How to Activate CSM
Key in the code "123654" via the standard RC transmitter.
Note: Activation of the CSM is only possible if there is no (user)
menu on the screen!
How to Navigate
By means of the "CURSOR-DOWN/UP" knob (or the scroll
wheel) on the RC-transmitter, can be navigated through the
menus.
Contents of CSM
The contents are displayed on three pages: General, Software
versions, and Quality items. However, these group names itself
are not shown anywhere in the CSM menu.

workshop as reference for further diagnosis. In this way, it
is not necessary for the customer to look at the rear of the
TV-set. Note that if an NVM is replaced or is initialized after
corruption, this set type has to be re-written to NVM.
ComPair will foresee in a possibility to do this.
