4.3.2 Component Side LSP
Figure 4-3 Service position 2
For better accessibility of the LSP, do the following (see figure
above):
1.
Remove the LSP-bracket from the bottom tray by pulling it
backwards.
2. Hook the bracket in the first row of fixation holes of the
bottom tray. In other words, reposition the bracket from [1]
to [2].
4.3.3 Solder Side LSP
Figure 4-4 Service position 3
To get access to the bottom side (solder side) of the LSP, do
the following (see figure above):
1.
Remove the DAF-module (see paragraph ‘DAF Assy/
panel’ below
2. To disconnect the degaussing coil from the LSP, remove
the cable from connector 1502 [1].
3. Release the wiring from their fixation clamps, in order to get
room for repositioning the LSP.
4. Flip the LSP 90 degrees clockwise [2], and place it in the
fixation hole at the left side of the bottom tray [3].
4.3.4 Small Signal Board (SSB)
In fact, there is no predefined service position for the SSB. Most
test points are located on the A-side (side that is facing the
tuner). If you have to replace ICs, you must take the complete
SSB module out of the SIMM-connector.
Note: For good access to the A-side, it is necessary to remove
the Auto-Scavem assy (at the left side of the SSB). See
description in paragraph 'Auto-Scavem Assy/Panel' below.
To get access to the SSB test points, do the following:
Figure 4-5 SSB removal (part 1)
1. Put the LSP in service position 2 (as described above).
2. Release the two clamps at the top of the SSB bracket [2]
and pull the bracket upward (it hinges in the bracket at the
LOT side).
3. Now you can remove the complete SSB bracket.
