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)
110402
Caution:
Always switch the set completely "OFF" (disconnected the
mains cord) before you remove or replace the SSB.
As the 5V2 standby voltage is always present (while the set is
switched "ON", in "standby" or in "Protection" mode) on the
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 bracket (at the left side of the SSB).
