5.1 Service Modes
The Service Mode feature is split into three parts:
• Service Alignment Mode (SAM).
• Factory Mode.
• Customer Service Mode (CSM).
SAM and the Factory mode offer features, which can be used
by the Service engineer to repair/align a TV set. Some features
are:
• Make alignments (e.g. White Tone), reset the error buffer
(SAM and Factory Mode).
• Display information ("SAM" indication in upper right corner
of screen, error buffer, software version, operating hours,
options and option codes, sub menus).
The CSM is a Service Mode that can be enabled by the
consumer. The CSM displays diagnosis information, which the
customer can forward to the dealer or call centre. In CSM
mode, "CSM", is displayed in the top right corner of the screen.
The information provided in CSM and the purpose of CSM is to:
• Increase the home repair hit rate.
• Decrease the number of nuisance calls.
• Solved customers' problem without home visit.
Note: For the new model range, a new remote control (RC) is
used with some renamed buttons. This has an impact on the
activation of the Service modes. For instance the old "MENU"
button is now called "HOME" (or is indicated by a "house" icon).
5.1.1 General
Next items are applicable to all Service Modes or are general.
Life Timer
During the life time cycle of the TV set, a timer is kept (called
"Op. Hour"). It counts the normal operation hours (not the
Stand-by hours). The actual value of the timer is displayed in
SAM in a decimal value. Every two soft-resets increase the
hour by + 1. Stand-by hours are not counted.
Software Identification, Version, and Cluster
The software ID, version, and cluster will be shown in the main
menu display of SAM, and CSM.
The screen will show: "AAAAAB-XXX.YYY.MMM.TTT", where:
• AAAAA is the chassis name: QM152.
• B is the region indication: E = Europe, A = AP, L = LATAM.
• X is the main version number: this is updated with a major
change of specification (incompatible with the previous
software version). Numbering will go from 1 - 99 and
AA - ZZ.
- If the main version number changes, the new version
number is written in the NVM.
- If the main version number changes, the default settings
are loaded.
• YYY is the sub version number: this is updated with a minor
change (backwards compatible with the previous
versions). Numbering will go from 000 - 999.
- If the sub version number changes, the new version
number is written in the NVM.
- If the NVM is refreshed, the software identification,
version, and cluster will also be written to NVM.
Service Modes, Error Codes, and Fault Finding
Display Option Code Selection
After an SSB or display exchange, the display option code is
not properly set, it will result in a TV with "no display". SSB and
display replacement requires setting all set option codes in
NVM to correct value.
In case option codes and white point setting must be set
manually:
On a standard remote control press key sequence: "062598"
directly followed by MENU and "xxx", where "xxx" is a 3 digit
decimal value of the panel type.
When the value is accepted and stored in NVM, the TV set will
switch to Stand-by indicating 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.
