Check that the sound from the HDMI
input is outputted.
Perform the “SOFTWARE VERSION
DISPLAY MODE” (refer to pa
ge 14
on the original service manual), and
check that the video micro-processor
version is not “0.00”.
Check that voltages of the connector pins
on the DIGITAL board are the following value.
DIGITAL board:
CN1501 pin1,2 : +6V
CN1501 pin 3,4 : +3.6V
CN1501 pin 5,6 : +3.3V
CN1501 pin 7,8 : +2.0V
CN1501 pin 9,10 : +2.5V
Check the following parts and the surrounding
circuit, and exchange the defective parts.
DCDC board: IC1900, IC1901, IC1902,
IC1903, IC1904, F940, F941
Check the following parts and the surrounding
circuit, and exchange the defective parts.
DIGITAL board: IC3506
Check the following parts and the surrounding
circuit, and exchange the defective parts.
DIGITAL board: IC2100, IC3001
Check the following parts and the surrounding
circuit, and exchange the defective parts.
DIGITAL board: X3000
Check that voltage of the following pin is 3.3 V,
1.3 V.
DIGITAL board: IC3506
pin18 : 1.2V ~ 1.3V
pin112: 3.3V(VOUT)
pin173: 3.3V
Check that voltage of the following pin is 3.3 V.
DIGITAL board: IC3000
pin57: 3.3V(RESET)
Check that the X3000 on the DIGITAL board is

Check that the sound is outputted from
each speaker, when the sound field is
“MULTI ST”.
Check that the speaker pattern setting is normal.
Explain the settings of this unit to the customer.
Check the surrounding circuit of power transistor
of the channel to which data is not outputted
(example: Q600 on the MAIN board) and the
surrounding circuit of power amplifier circuit
(example: FL, FR on the MAIN board), and
exchange the defective parts.
