Needs repair either a output ic or a diode near one of the outputs most often takes care of it. Not a job for a diy-er.

You mean SONY, right?

Generally speaking, an amp protects itself from heat, shorts and overloads.


Overloads can be from excessive periods of high output 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 hands-on tech.

Check the speaker connection. One of them has a shortcircuit. Try to disconect all of them and power on the device. See what is happen. If starts corectly check the speaker cable. Conect one by one and power up the receiver after each connection. When you get the error again check the last conected cable. These receivers have a protection system against shortcircuits. That is puting your device in that error.

SOURCE: WHEN THE POWER IS TURN

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.

My Sony home theater DZ290K had a push power protection on the display screen 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?

You may also refer to the following link for additional troubleshooting steps.

When I turn on my Home Theater Sony Model hcd-hdx576wf this message appears, "protector, push power". what I can do?


Follow the steps below to troubleshoot if the word PROTECT or PROTECTOR is flashing on the A/V receivers display.
1. Check the speaker wires and speakers for proper connections.
2. Reduce the volume level. IMPORTANT: If the receiver is played back at maximum volume level it may enter the protect mode. Maximum volume listening will cause the receiver to run very hot and may drain the output capacitors.
3. Disable the surround sound option if both the A and B speakers are being used simultaneously.
4. Ensure the top of the receiver has proper ventilation to keep it from overheating.
5. If the message only occurs when using a DVD player, the sampling frequency may be set too high. IMPORTANT: Some receivers provide compatibility with the higher sampling frequencies through alternate connections. Consult the owners manual for specific information.
6. Unplug the AC power cord for about 1 to 2 hours to reset the output transformers.
