What to do if there is no audio and my Panasonic SC-HTB520 Home Theater System turns off automatically?

If there is no audio and your Panasonic Home Theater System turns off automatically, it could be due to a safety measure activated when the unit detects a problem. If the volume is extremely high, lower it. If the unit is in an extremely hot place, move it to a cooler place and wait a few moments before trying to turn it on again. If the problem persists, turn the unit off and remove the AC mains lead cord and consult your dealer. There is a problem with the amplifier.
