5.1.7 FLOWCHART OF FAILURE ANALYSIS FOR THE AUDIO SYSTEM
Is a signal output from IC4701?
(pin 33, 34)
Check the surrounding of IC4701
and each input signal. If there was
no ploblem, replace the MAIN ASSY.
No
Check the communication
between IC4701 and CN4005.
No
NG
Replace the MAIN Assy.
NG
Replace the TANSHI Assy.
NG
Replace the TANSHI Assy.
Cansel muting then check again.
Is the volume set to 0?
Check around IC4704.
Yes
Yes
Has the signal come to TP8825
or TP8826?
Yes
Yes
Yes

Yes
No audio from monitor out
Yes
Yes
Has the sound been emitted from
the Subwoofer?
Yes
Is a signal output from IC4701?
(pin 31, 32)
Yes
Is a signal output from IC4704?
(pin 1, 7)
Has the signal arrived at CN4005?
Check the around of IC4701 and
each input signal. If there was no
ploblem, replace the MAIN ASSY.
⇒ SUB-W
No audio output from subwoofer
