FLOW CHART NO.13 (704-6K2-A618 IO PCB ASS'Y, 704-6K2-A617 : MAIN PCB ASS'Y)
Sound of LINE input is not being output correctly
Are the PH(6pin:CN1), FFC(24pin:CN102), and
FFC(20pin:CN801) correctly connected?
• Set the channel input source switch to "LINE"
• Set the CROSS FADER CONTOUR to "THRU"
• Set the input level volume to "12:00"
• Set the Cannel FADER to "MAX".
• Set the master level volume to "14:30".
Are audio signals output to 7pin(Lch), 1pin(Rch) of U505
when an audio signal of 1kHz 0dBV is input externally to the
LINE input?
Are the audio signals outputted to 11 pin and 12 pin of U751?
Are the digital audio signals (0-3.3V) outputted from 4 pin of
U751?
Check surrounding circuit of 88 pin of IC902 from 4 pin of
U751, and replace any faulty parts.

Connect the connector cable and FFCs correctly.
Check surrounding circuit of U505 from K500, and service it if
NO
defective.
When the surrounding circuit is correct, replace U505.
NO
Check periphery circuit of U751 from U505, and replace any
faulty parts.
When the periphery circuit is correct, replace U751.
NO
Replace any faulty parts.
NO
Connect the FFC (32pin:CN100) correctly.
NO
Check surrounding circuit of CN100 from D432/D433/D443/
D444, and service it if defective.When the surrounding circuit
is correct, replace FFC cabel.
NO
Check surrounding circuit of IC100 from CN100, and service it
if defective.
