This is an error massage and comes when home theater got some internal problem specially in amplifier output section that can have defective output IC etc.
It is not user level repair and requires qualified tech for fix.
Thanks.

Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on.

Overloads can be from excessive periods of high output or marginally low impedance loading by the speakers; and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced and competent hands-on tech.

Hi I have bought a new sony DAV-DZ310 model home theatre.I have connected all the speakers and a woofer.All are working fine except the center speaker.It is not at all working.I have made the connections...


This may not be Dependant on the Music or DVD, but with the setting on the Home Theater system. Try out all the modes - such as 2 Speaker, Multi etc. within the Home Theatre system. In one of the mode only the center speaker works.
Hope this helps. Good Luck.
