Test Points
As most signals are digital, it will be difficult to measure
waveforms with a standard oscilloscope. However, several key
ICs are capable of generating test patterns, which can be
controlled via ComPair. In this way it is possible to determine
which part is defective.
Perform measurements under the following conditions:
Service Default Mode.
Video: Colour bar signal.
Audio: 3 kHz left, 1 kHz right.
Service Modes
Service Default mode (SDM) and Service Alignment Mode
(SAM) offers several features for the service technician, while
the Customer Service Mode (CSM) is used for communication
between the call centre and the customer.
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)
To create a pre-defined setting, to get the same
measurement results as given in this manual.
To override SW protections detected by the standby
processor and make the TV start up to the step just before
protection. See section
To start the blinking LED procedure where only LAYER 2
errors are displayed. (see also section

All picture settings at 50% (brightness, colour, contrast).
Sound volume at 25%.
How to Activate SDM
For this chassis there are two kinds of SDM: an analogue SDM
and a digital SDM. Tuning will happen according
Analogue SDM: use the RC-transmitter and key in the
code "062596", directly followed by the "MENU" (or
"HOME") button.
Note: It is possible that, together with the SDM, the main
menu will appear. To switch the main menu "off", push the
"MENU" (or "HOME") button again.
Analogue SDM can also be activated by grounding the
solder path on the SSB, with the indication "SDM" (see

Digital SDM: use the RC-transmitter and key in the code
"062593", directly followed by the "MENU" (or "HOME")
Note: It is possible that, together with the SDM, the main
menu will appear. To switch it "off", push the "MENU" (or
"HOME") button again.
After activating this mode, "SDM" will appear in the upper right
corner of the screen (when a picture is available).
How to Exit SDM
Use one of the following methods:
Switch the set to STANDBY via the RC-transmitter.
Via a standard customer RC-transmitter: key in "00"-
Service Alignment Mode (SAM)
To perform (software) alignments.
To change option settings.
To easily identify the used software version.
To view operation hours.
To display (or clear) the error code buffer.
How to Activate SAM
Via a standard RC transmitter: Key in the code "062596"
directly followed by the "INFO" or "OK" button. After activating
SAM with this method a service warning will appear on the
screen, continue by pressing the "OK" button on the RC.
