Service Modes
The Service Mode feature is split into five parts:
1. Service Default Mode (SDM).
2. Service Alignment Mode (SAM).
3. Factory Mode.
4. Customer Service Mode (CSM).
5. Computer Aided Repair Mode (ComPair). SDM, SAM and the Factory mode offer features, which can be used by the Service engineer to repair/align a TV set. Some features are:
A. A pre-defined situation to ensure measurements can be made under uniform conditions (SDM).
B. Activates the blinking LED procedure for error identification when no picture is available (SDM).
C. Make alignments (e.g. White Tone), reset the error buffer (SAM and Factory Mode).
D. Display information (“SDM” or “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.

ComPair
Mode is used for communication between a computer and a TV on I2C /UART
level and can be used by a Service engineer to quickly diagnose the TV
set by reading out error codes, read and write in NVMs, communicate with
ICs and the micro processor (PWM, registers, etc.), and by making use
of a fault finding database. It will also be possible to up and download
the software of the TV set via I2C with help of ComPair. To do this,
ComPair has to be connected to the TV set via the ComPair connector,
which will be accessible through the rear of the set (without removing
the rear cover).
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)

Service Default Mode (SDM)
Purpose
Set the TV in SDM mode in order to be able to create a predefined setting for measurements to be made. In this platform, a simplified SDM is introduced (without protection override and without tuning to a predefined frequency).
Specifications
# Set linear video and audio settings to 50%, but volume to 25%. Stored user settings are not affected.
# All service-unfriendly modes (if present) are disabled, since they interfere with diagnosing/repairing a set. These service unfriendly modes are:
(Sleep) timer.
Blue mute/Wall paper.
Auto switch “off” (when there is no “ident” signal).
Hotel or hospital mode.
Child lock or parental lock (manual or via V-chip).
Skipping, blanking of “Not favourite”, “Skipped” or “Locked” presets/channels.
Automatic storing of Personal Preset or Last Status settings. back/OFF automatically.

Specifications
# Ignore “Service unfriendly modes”.
# Line number for every line (to make CSM language independent).
# Set the screen mode to full screen (all contents on screen is visible).
# After leaving the Customer Service Mode, the original settings are restored.
# Possibility to use “CH+” or “CH-” for channel surfing, or enter the specific channel number on the RC.
