Troubleshooting
No Sound
Check following steps.
Check IC5001 and peripheral circuit.
Check 1V power supply.
check if the audio signal
is observed at pins 7 and
15 of Ic5001.
Check audio output circuit.
Check speaker, connection of the terminal “K8F”.
Yes
No
Check IC001, IC5081 and peripheral circuit.
Check the Mute signal at pin 4 of IC001. The Mute signal is output from
pin 344 of IC 301<Scaler>. The OUT_DET signal is sent from Audio Out
terminal.
Mute-On: H at pin 344 of IC301, H at pin 4 of IC001.
Check the shutDown signal at oin of IC001. The ShutDown signal is
output from pin 18 of IC301.
AV_ShutDown_ON: H at pin 18 of IC301, L at pin of IC001.
check if the audio signal
is observed at pins 5 and
6 of Ic001.
Yes
No
