ComPair
First install the ComPair Browser software before connecting
ComPair to the EM5E-DVD (see the ComPair Browser Quick
Reference Card for installation instructions). In the EM5E-DVD,
you must diagnose the TV (plus DVD-interface panel) and the
DVD-module separately. Always start the diagnosis by
connecting the ComPair tool to the TV set. If something is
wrong with the DVD-module, ComPair will explain how and
when to connect the ComPair tool to the DVD-module.
Connection to the TV set:
1. Connect the RS232 interface cable to a free serial (COM)
port of the PC, and to the ComPair interface PC connector
(connector marked with 'PC').
2. Connect the mains adapter to the connector marked
'POWER 9V DC' of the ComPair interface.
3. Switch the ComPair interface OFF.
4. Switch the television set OFF with the mains switch.
5. Connect the interface cable (3122 785 90004) to the
connector on the rear side of the ComPair interface that is
marked 'I2C'
Figure 5-1 ComPair Interface Connection.
1. Connect the other end of the interface cable to the
ComPair connector on the rear-side of the set.
2. Plug the mains adapter in the mains outlet and switch ON
the interface. The green and red LEDs light up together.
The red LED extinguishes after approx. 1 second (the
green LED remains lit).
3. Start-up ComPair and select 'File' menu, 'Open'..; select
'EM5E-DVD' and click 'OK'.
4. Follow the instructions given on the screen for further
diagnosis (note that the OSD works but that the actual user
control is disabled).

Repair Tips
When re-assembling the DVD board or DVD Interface
make sure the routing of the cables is as instructed in
chapter "Mechanical Instructions". Incorrect routing can
lead to picture disturbance (vertical dark bars in DVD
mode) or EMC problems.
When DVD door does not open, check Service Alignment
Mode - 'Dealer Options' - 'Personal Options' - 'DVD door
lock': this must be set to 'NO'. This option can be used to
lock the DVD door in demonstration situations
