4.3.3 Component Side LSPTo get access to the bottom side (solder side) of the LSP, do
the following (see figure above):
1. Unlock the DAF-module bracket (see paragraph 'DAF
SSB top-bracket
Assy/Panel' further down).
SSB2. Unlock the Double Window, PIP module (if present),
release the locking clip and pull the bracket out of the

LSP3. Disconnect the degaussing coil connector 1502 [1] from
the LSP.
4. Release the high voltage cable out of its guiding clamp.
5. Release the wiring from their fixation clamps, in order to
position the LSP in the service position.

Caution:
For better accessibility of the LSP, do the following (see figure
above):Always switch the set completely ?OFF? (disconnect the mains
cord) before you remove or replace the SBB.
1. Remove the LSP-bracket from the bottom tray by pulling it
backwards.As the 5V2 standby voltage is always present (while the set is
2. Hook the bracket in the first row of fixation holes of the switched ?On?, in ?Standby? or in ?Protection? mode) on the
bottom tray. In other words, reposition the bracket from [1] SIMM connector, it is very risky to remove the SSB in this
situation, because the risk of short circuiting is very great.

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 ?Assy/Panel removal' to remove the
Auto-Scavem panel/bracket.
