Troubleshooting Sony Home Theatre PROTECT Mode

Your Sony home theatre is in PROTECT mode if it displays the words PROTECT/PROTECTOR on the receiver. The mode is also on if the words PROTECTOR and PUSH POWER alternate on your device.

This mode is normal and will not damage your device as long as you follow the correct troubleshooting tips.

How To Remove PROTECT Mode

If the PROTECT message is flashing on your Sony home theatre, below are some solutions you can try:

  • Turn off the device.
  • If there was a recent power outage or surge, you need to reset the internal surge protection circuit. Turn off and unplug the device from the power outlet. Disconnect any speakers or amplifiers. Leave it off for at least 30 minutes before turning it back on. 
  • If you use the device continuously during the day, it could overheat. Let the device cool for at least 15 minutes or more. To prevent overheating, keep your device in a well-ventilated cabinet. 
  • Reduce the volume of the speakers. The speakers might be outside of the specifications for the home theatre. If that's the case, replace them with the appropriate type. If you cannot replace the speakers, you can auto-calibrate them by entering SPEAKER SETUP.

After trying each solution, you should check the A/V receiver status. The A/V receiver is a multi-channel device that's vital for home theatre system functions.

PROTECT Mode Shows When Speakers Are Not Connected

Another issue that might trigger the PROTECT message is a disconnected speaker in the system. All of the speakers must be connected to the device. You can solve the issue by following the process below:

  1. Connect all the speaker cords to the correct terminals.
  2. Turn off the device. Check the following after STANDBY disappears:
    • Any short-circuit of the + and - speaker cords
    • Any blockage in the ventilation holes of the device
  3. If there are no issues, turn on the device.

If the PROTECT message still appears, take the device to a Sony service center.

What Does The PROTECT Mode Do?

For home theatre devices, the PROTECT mode prevents damage to internal parts. The mode also protects the speakers, amplifiers, or anything that's connected.

The device enters this mode if there is an electrical surge or power outage. When the device experiences a strong signal or a short circuit, the PROTECT message will appear on the receiver.

You will not be able to use the device, specifically the speakers, if it is in PROTECT mode. You can only use the device when you have solved the issue. 

What Causes The PROTECT Mode To Appear?

Your Sony home theatre will display the PROTECT message due to an external speaker problem or connection issues affecting the protection circuit. 

Here are the common reasons:

  • Covered receiver
  • Frayed or in-contact cords
  • Short-circuits after an electric surge or power failure
  • Overloading by attaching too many speakers
  • Poor or blocked ventilation
  • Using a low-impedance speaker
  • Faulty internal components

Learn below how you can prevent the receiver from flashing the PROTECT message.

How To Avoid Entering PROTECT Mode

The PROTECT mode will disrupt your entertainment activities. You can avoid this problem with your home theatre if you follow the tips below:

  • Make sure the wires connect to the right terminals.
  • Make sure the device is properly ventilated, so you avoid overheating.
  • Remove objects blocking the receiver from the connected speakers, amplifiers, or other audio and video devices. 
  • Use speakers with impedance within the specified range of your device's model. If you use a low-impedance speaker, auto-calibrate it first. 

When you know how to care for your Sony home theatre, you can maximize its functions and keep it in good condition.

Can The Speaker Impedance Differ From The Receiver?

According to Sony, if you match the A/V receiver with low-impedance speakers, it damages the receiver hardware. The ohm rating of home theatre receivers and speakers ranges from 4 to 8 ohms.

You should check the ohm rating of the device to ind the right speakers. The ohm rating of your desired speaker should have an impedance greater or equal to the home theatre's rating.

The higher the ohm rating, the higher the impedance. As a result, the flow of power from the speakers to the system will be better.

How To Set Up Speakers With Sony Home Theatre System

Below are the steps to follow:

  2. Prepare the speaker cords and check the terminals these connect to.
  3. There are various types of terminals at the rear of the terminal. Each has a different way to connect.
    • Spring clips: Press both red and black clips, then insert the speaker cord on the slot. Release the clips afterward.
    • Binding post: Loosen the red and black posts by turning them counterclockwise. Insert the cords, and tighten them by turning them clockwise.
  4. Afterward, connect the end of the cord to the speakers.
