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)

How to Exit SDM
• Switch the set to Stand-by, by pressing the standby button on the remote control transmitter or on the television set.
• Via a standard customer RC-transmitter: key in “00”-sequence.
Note: If the TV is switched “off” by a power interrupt while in SDM, the TV will show up in the last status of SDM menu as soon as the power is supplied again. The error buffer will not be cleared.
Service Alignment Mode (SAM)
