3) During repair it is possible to disconnect the Tuner board
and CDC Module completely unless the fault is sus-
pected to be in that area. This will not affect the
performance of the rest of the set.
4) Due to the short flex cable wires in the ETF Module, the
pc board should be disconnected and reconnected on
the reverse side of the tape mechanism to keep it
electrically connected during repair. See picture 3.
Note: The flex cables are very fragile, care should be taken
not to damage them during repair. After repair, be
very sure that the flex cables are inserted properly
into the flex sockets before encasing, otherwise faults
may occurs.
Use a insulation sheet to prevent
the AF board from being damaged
or short-circuit to any metal parts.
