                 Yes> go to step 3.

                 No > Replace the speakers.

                 3 .    Check the signal circuits of speakers

                                                           (a)    Disconnect the connectors of the acoustics
                                                                  unit.                                              04






















                                                           (b)    Use a multimeter to measure the resistance
                                                                  between the pins of connector C045 of
                                                                  acoustics unit respectively.
                                                                  Standard voltage

                                                            Multimeter connection          Standard value

                                                                C045(5)-C045(6)                ≥ 1 MΩ

                                                                C045(3)-C045(4)                ≥ 1 MΩ

                                                               C045(7)-C045(8)                 ≥ 1 MΩ
                                                               C045(1)-C045(2)                 ≥ 1 MΩ





                 Check whether the result is normal?
                 Yes> go to step 4.

                 No > Repair the short circuit between connector C045 of acoustics unit and the
                 speakers.

                 4 .    Check the acoustics unit module.
