How to Navigate
•
In SAM, the menu items can be selected with the
“CURSOR UP/DOWN” key (or the scroll wheel) on the RC-
transmitter. The selected item will be highlighted. When not
all menu items fit on the screen, move the “CURSOR UP/
DOWN” key to display the next/previous menu items.

With the “CURSOR LEFT/RIGHT” keys (or the scroll
wheel), it is possible to:
–
(De) activate the selected menu item.
–
(De) activate the selected sub menu.
•
With the “OK” key, it is possible to activate the selected
action.
How to Exit SAM
Use one of the following methods:
•
Switch the set to STAND-BY via the RC-transmitter.
•
Via a standard RC-transmitter, key in “00” sequence, or

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.
When in this 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.
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.
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.
Remark: the content here can also be a part of the 12NC of
the SSB in combination with the serial number.
