Software Downloading
In this chassis, you can upgrade the software via ComPair. You
can find more information on how this procedure works in the
ComPair file. It is possible that not all sets are equipped with
the hardware, needed to make software upgrading possible. To
speed up the programming process the firmware of the
ComPair interface can be upgraded. See paragraph “How To

Error codes of devic-
es on slow I2C bus.
When there are errors on
the slow bus it is possible
that the TDL interface,
DVD or radio module
caused them.
When you clear the error buffer and do a functional test. Make sure you activate all modes
available: TV, DVD and Radio in the user menu. By doing this all modules are activated and
tested and possible error codes are logged. Another option is: You disconnect the flat cable
(connector 1250) on the interface board TDL (T) to pinpoint where the problem is located
on the slow bus.
Various symptoms,
due to missing local
supply voltage.
An interrupted fuse, NFR-
resistor or connection.
When no symptom or error code leads you to a specific circuitry, use the supply lines over-
view (see supply lines overview), for a quick scan of all supply lines.
