Note: Figures below can deviate slightly from the actual
situation, due to the different set executions.
4.1 Service Connector (for ComPair)
For service diagnostics with ComPair, it is not necessary to
disassemble the set. You only have to connect the ComPair
interface box, via the appropriate cable, to the service
connector (on the rear of the set, see figure below), and start
the program (see also chapter 5).
4.2 Set Disassembly
Follow the disassemble instructions in described order.
4.2.1 Wireless Surround Transmitter Removal (if attached)
1. Remove the cable of the Wireless Surround Transmitter
box (at the right side of this RJ45 plug you can find the
release-hook of the lock-mechanism).
2. Pull the Wireless Surround Transmitter box backwards. It
is clicked to the rear cover via three clamps.
4.2.2 Rear Cover Removal
Figure 4-1 Rear view
Warning: disconnect the mains power cord before you remove
the rear cover.
First, remove the top cover (= plate with 'saucer'):
1.
Remove the three fixation screws [1] that hold the cover
plate.
2. Pull the cover (horizontally) backwards.
To be able to access the electronics of the set, you must
remove the rear cover:
1.
Remove the fixation screws [2] of the rear I/O cover plate.
2. Remove the remaining fixation screws [3] at the two sides,
and the top of the rear cover.
3. Now remove the rear cover. Make sure that wires and
cables are not damaged during cover removal.
4.2.3 Sub-woofer Removal
Caution: Do not disconnect the loudspeaker cable from the
subwoofer box when the set is operative, because the class-D
amplifier cannot handle a change in load during operation.
It is no problem when the subwoofer is disconnected before
operation, but a change from connected to disconnected
during operation can damage the amplifier.
1.
Disconnect the loudspeaker cable at the top of the sub-
woofer box.
2. The subwoofer is fixed in the bottom plate with two 'rubber
feet'.
3. Pull the sub-woofer box upwards, and remove it.
4.3 Service Positions
This chassis has several predefined service positions, for
better accessibility. They are explained below in more detail.
4.3.1 Solder Side ‘3rd SCART’ panel
Figure 4-2 Service position 1
To remove or access the ‘3rd SCART’ panel, do the following:
1.
Remove fixation screw [1].
2. To release the fixation peg, push it towards the CRT [2].
3. At the same time, pull the complete module away from the
LSP [3]. It hinges in the LSP-bracket.
4. To remove the panel, disconnect the flat-cable from
connector 1680 and remove the four panel screws [4].
