What to do if no audio and power switches off automatically on Panasonic SC-HTB490?

If there is no audio and the power of the main unit switches off automatically on your Panasonic Home Theater System, there may be a problem with the amplifier. Disconnect the AC mains lead and consult the dealer. If the volume is extremely high, lower it. If the system is in an extremely hot place, move it to a cooler place, wait a few moments, and then try to switch it on again. If the problem persists, confirm the indicators' status, switch off the system, disconnect the AC mains lead, and consult your dealer, remembering the indicators' status to inform them.
