Contents of CSM
•
1.1 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.
•
1.2 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.
•
1.3 Installation date Indicates the date of the first
installation of the TV. This date is acquired via time
extraction.
•
1.4 Option Code 1 Gives the option codes of option group
1 as set in SAM.
•
1.5 Option Code 2 Gives the option codes of option group
2 as set in SAM.
•
1.6 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. This identification number is the 12NC number of the
SSB.
•
1.7 Display Displays the 12NC of the NVM.
•
1.8 PSU Displays the 12NC of the PSU.
•
2.1 Current Main SW Displays the built-in main software
version. In case of field problems related to software,
software can be upgraded. As this software is consumer
upgradeable, it will also be published on the Internet.
•
2.2 Standby SW Displays the built-in stand-by processor
software version. Upgrading this software will be possible
via USB.
•
2.3 Panel Code Displays the Display Code number.
•
2.4 NVM version Detects and displays NVM version.
•
3.1 Child lock Not active/active. This is a combined item
for locks. If any lock (channel lock, parental lock) is active,
the item shall show “active”.
•
3.2 HDCP keys Indicates if the HDMI keys (or HDCP keys)
are valid or not. In case these keys are not valid and the
customer wants to make use of the HDMI functionality, the
SSB has to be replaced.
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.
How to Exit CSM
To exit CSM, use one of the following methods.
•
Press the MENU/HOME button on the remote control
transmitter.
•
Press the POWER button on the remote control
transmitter.
•
Press the POWER button on the television set.
5.2.5
Blind SAM Display Option Code Selection
When after an SSB or display exchange, the display option
code is not set properly, it will result in a TV with “no display”.
Therefore, it is required to set this display option code after
such a repair.
To do so, press the following key sequence on a standard RC
transmitter: “062598” directly followed by MENU and “xxx”,
where “xxx” is a 3 digit decimal value of the panel type: see
column “Display Code” in
. When the value is
accepted and stored in NVM, the set will switch to Stand-by, to
indicate that the process has been completed.
During this algorithm, the NVM-content must be filtered,
because several items in the NVM are TV-related and not SSB
related (e.g. Model and Prod. S/N). Therefore, “Model”
and “Prod. S/N” data is changed into “See Type Plate”. In case
a call centre or consumer reads “See Type Plate” in CSM
mode, he needs to look to the side/bottom sticker to identify the
set, for further actions.
