How to fix no sound from Onkyo Home Theater System speakers?
If you're experiencing no sound from the speakers of your Onkyo Home Theater System, first, make sure that headphones are not connected to the PHONES jack. If they are, disconnect them. Also, if signals other than PCM are being input, change the setting in the Setup menu to Off.
Why does my Onkyo Home Theater System turn off unexpectedly?
Your Onkyo Home Theater System might be turning off unexpectedly due to several reasons. It could be that the 'Auto Standby' feature in the Setup menu is activated, causing the unit to automatically enter standby mode. Another reason might be that the protection circuit function has been activated due to an abnormal rise in temperature. In this case, ensure sufficient ventilation around the unit and wait for it to cool down before turning it on again. If you notice smoke, smell, or abnormal noise, unplug the power cord immediately.
What to do if "AMP Diag Mode" appears on my Onkyo HT-S3910DAB display?
If "AMP Diag Mode" appears on the display of your Onkyo Home Theater System, it indicates that the protection circuit function may have been activated. This function diagnoses whether the unit is malfunctioning or if there's an issue with the speaker cable connection. Ensure that the speaker cable is properly connected, and the wires exposed from the tip of the speaker cable do not stick out of the speaker terminal. If the operation stops with "NG" displayed, immediately set the unit to standby, remove the power plug, and consult a dealer.
