The following is a flowchart for failure diagnosis when the audio signal is not output from the AUDIO OUT jack (stereo mini).
No sound (the audio signal is not output
from the AUDIO OUT jack)
YES
Is the cable that connects between the AUDIO
OUT jack and the equipment broken or short-
circuited to ground?
Change the connecting cable.
NO
NO
Is the connected equipment terminated with
22 kohms or more?
Connect equipment whose input impedance is 22
kohms or more. (No sound when the connected
equipment is terminated with 75 ohms)
YES
NO
Is 12-Vdc power input to Pin 14 of IC5308?
Failure in IC5308 or IC5306
YES
NO
Is an audio waveform output from the audio input
terminal of IC5308 (Pin 1 for INPUT 1, Pin 3 for
INPUT 2, or Pin 5 for video slot input)?
Failure in the equipment connected via the input
connector, or poor connection of the audio input
connector
YES
NO
Is an audio waveform output from Pin 15 of
IC5308?
The connector (INPUT 1-5) to which
the audio signal is input is not
selected, or failure in IC5308.
YES
Failure in the audio muting circuit on the MAIN
PWB for the AUDIO OUT connector, or poor
connection of the AUDIO OUT connector.
