Repair Hint
1) During repair it is possible to disconnect the Tuner
Board and CDC Module completely unless the fault is
suspected to be in that area. This will not affect the
performance of the rest of the set.
2) Due to the short flex cable wires in the ETF Module, the
PCB should be disconnected and reconnected on the
reverse side of the tape mechanism to keep it
electrically connected during repair. see Figure 19.
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.
