Press the [A.F.D.] button
to select the “MULTI ST”,
and check that the sound
by various sauce
(example: coaxial input,
analog input) is outputted
from all the channels (FL/
FR/SL/SR/SBL/SBR/C/SW).
Check that sound occurs
from the RY921 on the MAIN
board by inserting and
removing headphone.
Check the following parts and the
surrounding circuit, and exchange the
defective parts.
DIGITAL board: IC2105 HP board: J101
MAIN board: Q375, RY921
Check the following parts and the
surrounding circuit, and exchange
the defective parts.
DIGITAL board: IC2105
DSP board: IC5001, IC5002, X5000
Check the following parts and the
surrounding circuit, and exchange
the defective parts.
DIGITAL board:
IC2105, IC2806, X2801
Check the following parts and
the surrounding circuit, and
exchange the defective parts.
DIGITAL board:
IC2010, IC2817, IC2818
DSP board: IC5003
Check that voltage of pins of the
CN2608 on the DIGITAL board is
the following value.
pin 45 : 2.5 V pin 47 : 3.3 V
Check that data is outputted from the
following pins.
DIGITAL board: IC2806 pin 16, 19, 20, 21
Check the following parts and the
surrounding circuit, and exchange the
defective parts.

Check the following parts and the
surrounding circuit, and exchange
the defective parts.
DIGITAL board: IC2105
MAIN board: IC400
Perform the “SOFTWARE VERSION DISPLAY
MODE” (refer to page 13 on the original
service manual), and check that the DSP
version is not “0.00”.
Press the [MUTING] button on
the remote commander once,
and check that the sound is
outputted from this unit.
Explain the settings of this unit
to the customer.
