Removing the back plate
It is only possible to remove the back plate after
removing the screws on the top, side, possibly on
the underneath
and possibly under the EXT 3

units, the subwoofer speaker on the carrier panel

Service position 1
Service position for module service and to measure
EXT
test points
Unlock the chassis after the cables of the
degaussing coil and any PIP module have been
disconnected, and pull it backwards until all test
points are accessible (see Fig. 4.2).
In order to make the tuner and the IF/sound module
accessible, the bracket above these modules can
be removed (see Fig. 4.3). With the exception of
one fault message, the unit continues to function
normally when the PIP module is not connected.

Service position 2
Service position for repair
Place the chassis on the heat sink on the tuner side
after service position 1 is reached (see Fig. 4.4).
Warning: make sure that the heat sink of the sound
output amplifier does not form a short circuit with
the raster/line heat sink if the bracket of the
euromodule has been removed!
