Generally speaking, an amp attempts to protect itself from heat, shorts, overloads and operator exuberance by refusing to turn on or stay on; or it may turn on but produce no audio to the speakers.

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 'nekkid'. 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.

Check for loose speaker connections at the speaker as another possible root cause for intermittent shutdown.

hello my frien let me tell you that the system wont accept more speakers or diferent loads per ohm if the total load says 16 ohms by channel thats the total can handle so if you ad more speakers the system turns off before it burns or or have a severe damage........saludos

Does it have a reset button or a fuse? check as some units have one or the other. Also check power cord to see if it is not apart as well check the plug itself. Could be the unit itself not working.

It is actually 2 messages being displayed one after the other, "PROTECT", and "PUSH POWER".

>>A strong signal was input. Press the power button to turn off the power, leave the system turned off for a while, then press the power button again to turn power back on.
>>Check the speaker cables in case "PROTECT" and "PUSH POWER" appear alternately again after you turn the system on.

Visit the link below:

If this continues I recommend you take the unit to a reputable repair shop for a diagnosis.
