4.3 Service Positions
4.4 Assy / Board Removal
4.5 Set Re-assembly
Note: Figures below can deviate slightly from the actual
situation, due to the different set executions.

4.1 Service Connector (for IAP)

For software uploading with the IAP tool (In Application
Programming), it is not necessary to remove EEPROMs from
the set. You only have to connect the IAP interface circuit to the
service connector (on the rear of the set, and start the software
uploading (see also chapter 5 "Service Modes, Error Codes,
and Fault Finding").

4.2 Set Disassembly

Follow the disassemble instructions in described order.
4.2.1 Rear Cover Removal
Warning: disconnect the mains power cord before you remove
the rear cover.
1. Remove all the fixation screws of the rear cover.
2. Now the rear cover can be removed.

4.3 Service Positions

Only the LSP of this chassis has a service position for better
access to the component side of the LSP. For the SSB, there
is no specific service position.
4.3.1 Large Signal Panel (LSP)
Component Side LSP
For better accessibility of the LSP, do the following (see
Figures “Service position LSP” and “Locking handles LSP”):
1. Simultanuously do the following: a) pull the two plastic
locking handles at the mid left and mid right side of the
bracket gently backwards to unlock the bracket, and b)
loosen the bracket from the bottom tray, by pulling it
backwards. N.B.: You do not need to pull the other two
locking handles backwards.
2. Remove the LSP-bracket from the bottom tray by lifting it
upwards.
3. Hook the bracket in the first row of fixation holes of the
bottom tray. In other words, reposition the bracket from [1]
to [2].
Figure 4-1 Service position LSP
Figure 4-2 Locking handles LSP
Solder Side LSP
To get access to the bottom side (solder side) of the LSP, do
the following:
1. Remove all the connectors from the LSP.
2. Remove the LSP, still in its plastic bracket, from the
chassis, so the bottom side of the LSP can be reached. If
necessary, remove the LSP also from its plastic bracket.
4.3.2 Small Signal Board (SSB)
There is no service position for the SSB. Most test points are
located on the component side. If you have to replace ICs, you
must remove the complete SSB module from the TV set (see
further down in this chapter: Small Signal Board, SSB).
