To access the bottom side (solder side) of the LSP, do the
following (see figure above):
1. Remove the DAF module (see paragraph "DAF Assembly/
Panel" below.)
2. To disconnect the degaussing coil from the LSP, remove
the cable from connector 1502 [1.]
3. Release the wires from their clamps to make room to
reposition the LSP.
4. Turn the LSP 90 degrees clockwise [2], and place it in the
hole at the left side of the bottom tray [3.]

Small Signal Board (SSB)
There is no predefined service position for the SSB. Most test
points are located on the A-side (the side that faces the tuner.)
If you have to replace ICs, you must take the complete SSB
module out of the SIMM-connector.
To access 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. Remove the fixation screw, which holds the SSB-bracket
[1.]
3. Release the clamping jaw at the top of the SSB bracket [2]
and [3.]
4. Push the two clamping lugs outwards, and pull the top of
the bracket at the same time upwards [4] and [5.]

5. Now you can remove the complete bracket. Push it, at the
height of the LSP-bracket, towards the CRT [6] and lift it out
of the LSP-bracket [7.]

1. Push the top of the SSB toward the LOT [1.]
2. Due to the pressure, the two metal clamps at both sides of
the SIMM-connector will release [2.]
3. Take the complete SSB out [3.]

1. Once you have taken out the SSB, remove the A-side
shielding [2.] Sometimes it is necessary to unsolder some
solder tags before doing this [1.]
2. Replace the SSB module in the SIMM-connector in reverse
order.
Notes:
•
For better access to the SSB, it is possible to order an
"extension board," which is part number 9965 000 05769.
•
If it is necessary for measurements, you can put the LSP in
"service position 3" (as described above.)

Assembly / Board Removal
Sometimes, it may be necessary to swap a complete assembly
or Circuit Board Assembly (CBA.) This procedure is explained
below.
