How to Repair Sony DAV-DZ510, push power protect
If the term PROTECT or PROTECTOR and PUSH POWER appear in alternating sequence on the display of your home audio device, or if the words PROTECT or PROTECTOR appear, there could also be an external speaker issue or connection issue that's triggering the protection circuit. Try following these steps to resolve this issue:
NOTE: Because each of those steps represents a possible solution to the present issue, check the A/V receiver status after completing each step.
If there has been an electrical surge or power failure , then the interior surge protection inside the house audio device may are triggered to guard the device from the surge. this is often normal. To reset the interior surge protection circuit unplug the AC cord from the wall for a minimum of half-hour .
Ensure the top of the house audio device has proper ventilation to stay it from overheating. Running the house audio device during a poorly ventilated cabinet can trigger the protection circuit.
Reduce the quantity level. If the impedance of any of the speakers is below the rated impedance range indicated on the rear of the house audio device next to the speaker connections, the house audio device may enter the PROTECT mode. Raising the quantity with a coffee impedance speaker will trigger the protection circuit.
NOTES:
Replace low impedance (outside of specifications) speakers with the right impedance to stop this from occurring.
If you still use the low impedance (outside of specifications) speakers and you ran the Auto Calibration, check your SPEAKER SETUP and individual speaker LEVEL to scale back any speaker LEVEL with a positive gain to 0.0dB or less.
To isolate the matter , do the following:
Turn off the house audio device, and take away all speaker wires from the rear . Then turn the device back on and check if the difficulty is resolved. If it's still having an equivalent issue, close up the device again and let it rest for a minimum of half-hour before turning it on again.
Inspect the speaker cords. If a cord is frayed or in touch with another terminal, a mistake will occur. Fix the connection to stop a brief circuit.
It sure the speaker impedance is within the approved range. If the impedance isn't correct, sound won't begin properly and therefore the speaker could also be damaged. If speakers that are within the recommended impedance range, check the connections. If the speakers getting used is within the acceptable range and remains not working, there could also be a malfunction or another flaw within the speakers. Test by employing a different set of speakers if available.
