Test Points
This chassis is equipped with test points in the service printing. In the schematics test points
are identified with a rectangle box around Fxxx or Ixxx. These test points are specifically
mentioned in the service manual as “half moons” with a dot in the centre.
Perform measurements under the following conditions:
l
Television set in Service Default Alignment Mode.
l
Video input: Colour bar signal.
l
Audio input: 3 kHz left channel, 1 kHz right channel.
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.
This chassis also offers the option of using ComPair, a hardware interface between a
computer and the TV chassis. It offers the abilities of structured troubleshooting, error code
reading, and software version readout for all chassis.
Minimum requirements for ComPair:
a Pentium processor, a Windows OS, and a CD-ROM
drive (see also paragraph 'ComPair').
