More diagnosis first.

Generally speaking, an amp protects 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.


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

Hello.. I have Sony MHCEX500 MINI HIFI Component system. There is a problem of PUSH POWER PROTECT. How can I fix it..????


The "PROTECT" and "PUSH POWER" messages will flash alternately when the protective device of the amplifier has been activated because a strong signal was input, or if there is a short-circuit detected. Press the POWER button on the unit to turn off the system, and check the following items after "STANDBY" disappears.

1) Are the + and - speaker cords short-circuited?
2) Are you using only the specified speakers?.
3) Is anything blocking the ventilation holes of the system?

Protect message


Protect means that a fault was detected, disconnect all the speakers

and connect one at a time to find the cause.

If symptoms persist , it needs repair, output stage or power supply

circuits should be the preliminary things to check.

While playing my unit we had a brief power outage. When the power supply returned the " PROTECT PUSH POWER " message comes on. Is there a button that I can push to reset my unit-LBT-X50 .


Hi,
Your sound system may have a circuit breaker.
Check the rear of the sound system for a circuit breaker that has popped out, Then push it back in.
It may be labelled.
  • circuit breaker
  • protect push power
Otherwise unplug your unit from the wall and wait 5min before you plug it back in, then press the power button on the front of your system and your remote control.

I hope this helps
