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 colour bar test
pattern will be visible for 5 seconds. This test pattern is
generated by the Pacific3. So if you see this test pattern you
can determine that the back end video chain (Pacific3, LVDS
and display) is working.
Also new in this chassis: when you activate CSM 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 your USB stick. This info can be handy
if you don't have picture.
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, you can navigate through the menus.
Contents of CSM
• 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 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 possibility to do
this.
• Code 1. Gives the latest five errors of the error buffer. As
soon as the built-in diagnose software has detected an
error the buffer is adapted. The last occurred error is
displayed on the leftmost position. Each error code is
displayed as a 2-digit number. When less than 10 errors
occur, the rest of the buffer is empty (00). See also
paragraph Error Codes for a description.
• Code 2. Gives the first five errors of the error buffer. See
also paragraph Error Codes for a description.
• 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 a possibility to do this.
This identification number consists of 14 characters and is
built up as follows:
- 8 last characters of the 12NC of the SSB itself.
- the serial number of the SSB, which consists of 6 digits.
Both can be found on a sticker on the PWB of the SSB itself
(not on the sticker on the outside of the shielding!). The
format of the identification number is then as follows:
<last 8 characters of 12NC of SSB><serial number of
SSB> (total 14 characters).
• Digital Natural Motion. Gives the last status of the Digital
Natural Motion setting, as set by the customer. Possible
Service Modes, Error Codes, and Fault Finding
values are "Off", "Minimum" and "Maximum". See DFU on

customer. Possible values are "Off", "Minimum", "Medium"
and "Maximum". See DFU on how to change this item.
• Noise Figure. Gives the noise ratio for the selected
transmitter. This value can vary from 0 (good signal) to 127
(average signal) and to 255 (bad signal). For some
software versions, the noise figure will only be valid when
"Active Control" is set to "medium" or "maximum" before
activating CSM. Noise figure is not applicable for DVBT
channels.
• Headphone Volume. Gives the last status of the
headphone volume, as set by the customer. The value can
vary from 0 (volume is minimum) to 100 (volume is
maximum). See DFU on how to change this item.
• Dolby. Indicates whether the received transmitter
transmits Dolby sound ("ON") or not ("OFF"). Attention: The
presence of Dolby can only be tested by the software on
the Dolby Signalling bit. If a Dolby transmission is received
without a Dolby Signalling bit, this indicator will show "OFF"
even though a Dolby transmission is received.
• Surround Mode. Indicates the by the customer selected
sound mode (or automatically chosen mode). Possible
values are "STEREO" and "VIRTUAL DOLBY
