If the issue is still unresolved, service may be required.

Test by using a different set of speakers if available. If the speakers being used are within the suitable impedance range and they are still not working, there may be a malfunction or some other flaw within the speakers. If the speakers are within the recommended impedance range, check the connections. If the impedance is not correct, the speakers will not work properly and may be damaged. Make sure the speaker impedance is within the recommended range.Fix the connection to prevent a short circuit. If a cord is frayed or in contact with another terminal, an error will occur. If it is still having the same issue, turn off the device again leave it off for at least 30 minutes before turning it on again.

Then turn the device back on and check if the issue is resolved. OK, I dug through the stacks of manuals and Viola Mine was Sony model STR-DE525 purchased in 1998. Turn off the home audio device, and remove all speaker wires from the back.To isolate the problem, do the following:.If you continue to use the low impedance (outside of specifications) speakers and you ran the Auto Calibration, check your SPEAKER SETUP and individual speaker LEVEL to reduce any speaker LEVEL with a positive gain to 0.0dB or less.Replace low impedance (outside of specifications) speakers with the correct impedance to prevent this from occurring.Raising the volume with a low impedance speaker will trigger the protection circuit.

If the impedance of any of the speakers is below the rated impedance range indicated on the rear of the home audio device next to the speaker connections, the home audio device may enter the PROTECT mode. Running the home audio device in a poorly ventilated cabinet can trigger the protection circuit. If the receiver powers on, continue connecting one pair of speakers at a time to find which speaker (or set of speakers) is causing the problem.

Ensure the top of the home audio device has proper ventilation to keep it from overheating. Paul: Power off the receiver and connect the main left and right speaker wires (for those models with both an A and B speaker set, test set A, then B individually).

To reset the internal surge protection circuit unplug the AC power cord from the wall for at least 30 minutes.

If there has been an electrical surge or power outage, then the internal surge protection inside the home audio device may have been triggered to protect the device from the surge.

NOTE: Because each of these steps represents a possible solution to this issue, check the A/V receiver status after completing each step. Try following these steps to resolve this issue: If the words PROTECTOR and PUSH POWER appear in alternating sequence on the display of your home audio device, or if the word PROTECT or PROTECTOR appears, there may be an external speaker issue or connection issue that is triggering the protection circuit. Manuals are posted on your model support page.
