5.1
Service Modes
The Service Mode feature is split into four 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: "AAAAAAB-XXX.YYY.MMM.TTT",
where:
•
AAAAAA is the chassis name: TPM165L.
•
B is the region indication: E = Europe, A = AP/China, U =
NAFTA, L = LATAM.

•
XXX is the main version number: this is updated with a
major change of specification (incompatible with the
previous software version). Numbering will go from 0- 255.
•
YYY is the sub version number: this is updated with a minor
change of specification (incompatible with the previous
versions). Numbering will go from 0- 255.
•
MMM is the number of the mandatory (upgrade) release in
association with the area of the mandatory (upgrade)
release. Numbering will go from 0 - 255.
•
TTT bit 7 to 1 is the area of the mandatory (upgrade)
release where 0 - none, 1 - Netflix, rest reserved.
•
TTT bit 0 : 0 = development release, 1 = production
release.
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
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.
5.1.2
Service Alignment Mode (SAM)
Purpose
•
To modify the NVM.
•
To display/clear the error code buffer.
•
To perform alignments.
Specifications
•
Operation hours counter (maximum five digits displayed).
•
Software version, error codes, and option settings display.
•
Error buffer clearing.
•
Option settings.
•
Software alignments (White Tone).
•
NVM Editor.
•
Set screen mode to full screen (all content is visible).
How to Activate SAM
To activate SAM, use one of the following methods:
•
Press the following key sequence on the remote control
transmitter: "062596", directly followed by the "INFO/OK"
button. Do not allow the display to time out between entries
while keying the sequence.
After entering SAM, the following items are displayed,
with "SAM" in the upper right corner of the screen to indicate
that the television is in Service Alignment Mode.
Description
This represents the life timer. The timer counts normal operation hours, but does
not count Stand-by hours.
See paragraph
Software Identification, Version, and Cluster
definition.
Shows all errors detected since the last time the buffer was erased. Five errors
possible.
Used to read-out the option bytes. See paragraph
Alignments section for a detailed description. Ten codes are possible.
