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 in this chassis CSM is activated, a testpattern will be
displayed during 5 seconds (1 second Blue, 1 second Green
and 1 second Red, then again 1 second Blue and 1 second
Green). This test pattern is generated by the PNX5100. So if
this test pattern is shown, it could be determined that the back
end video chain (PNX5100, LVDS, and display) of the SSB is
working.
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 info can be handy if no information is displayed.
Also 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
).
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 on the RC-
transmitter, can be navigated through the menus.
Contents of CSM
The contents are reduced to 3 pages: General, Software
versions and Quality items. The group names itself are not
shown anywhere in the CSM menu.
General
• Set Type. This information is very helpful for a helpdesk/
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.
• Production Code. Displays the production code (the serial
number) of the TV. Note that if an NVM is replaced or is
initialized after corruption, this production code has to be
re-written to NVM. ComPair will foresee a in possibility to
do this.
• Installed date. Indicates the date of the first installation of
the TV. This date is acquired via time extraction.
• Options 1. Gives the option codes of option group 1 as set
in SAM (Service Alignment Mode).
• Options 2. Gives the option codes of option group 2 as set
in SAM (Service Alignment Mode).
• 12NC SSB. Gives an identification of the SSB as stored in
NVM. Note that if an NVM is replaced or is initialized after
corruption, this identification number has to be re-written to
NVM. ComPair will foresee in a possibility to do this. This
identification number is the 12nc number of the SSB.
• 12NC display. Shows the 12NC of the display.
• 12NC supply. Shows the 12NC of the supply.
