Reduce the volume level. Thanks for the tip. This together with a state-of-the-art Japanese electronic protection mechanism ensures that they will survive for many years. In this channel example, the non-flammable power resistor is R716 which is a twin resistor package consisting of a pair of 0.22 ohm resistors in series. Manuals are posted on your model support page. 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. Go to Product Repair. Steps to Play Music from a Google Home-Enabled App to the Home Speakers or Other Audio Devices, Steps to Perform a Power Reset on your Home Audio or Video Product, Can't hear TV sound from the soundbar, home theater system, or home audio system, Audio from the soundbar or home theater and is out of sync with the TV picture, All Mobile, Tablets & Smart Devices products. Running the home audio device in a poorly ventilated cabinet can trigger the protection circuit. Manuals are posted on your model support page. Ensure the top of the home audio device has proper ventilation to keep it from overheating. This is normal. We recommend downloading and installing the latest version of one of the following browsers: Our site is not optimized for your current browser. This is typically caused by some speaker wires shorting between the + and - terminals somewhere. If the words PROTECT / 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 may be an external speaker issue or connection issue that is triggering the protection circuit. Inspect the speaker cords. To isolate the problem, do the following: Turn off the home audio device, and remove all speaker wires from the back. Be among the first to get the latest If the impedance is not correct, the speakers will not work properly and may be damaged. The protection mechanism usually places the amplifier into protect mode when it detects a short, and during this time it prevents power to the amplifier circuitry, thereby preventing harm to the speakers and expensive amplifier components. In the following It looks like JavaScript is disabled in your browser. These are hardy transistors with collector current (Ic) rated at 10-A. Let the amplifier cool for 15 minutes and then switch ON to see if the message still appears. To reset the internal surge protection circuit unplug the AC power cord from the wall for at least. Launch it after it is successfully installed and click on "Remove screen Lock " to start the unlocking process. 3- In the protected screen enable one wifi network, after already one authenticates Wi-Fi network does not restart the machine and knife Step 3 4- Enable guest mode. Fix the connection to prevent a short circuit. This is a complex piece of Japanese electronic engineering and it requires a fully qualified and experienced electronic engineer to repair it, therefore do not attempt to repair it. Ensure the top of the home audio device has proper ventilation to keep it from overheating. Running the home audio device in a poorly ventilated cabinet can trigger the protection circuit. I can turn the volume up now . NOTE: If model-specific information is needed to complete any of these steps, refer to the instruction manual with the product. Replace low impedance (outside of specifications) speakers with the correct impedance to prevent this from occurring. If the speakers are within the recommended impedance range, check the connections. The purpose of the protect error is to protect the amplifier components from damage should a short circuit occur. To reset the internal surge protection circuit unplug the AC power cord from the wall for at least 30 minutes. If we look at one side of the push-pull stage, we see that if Q703 goes short between its collector and emitter junctions, the voltage rail would flow through the speaker and ground, however, there is R716 in the path, which will go open.
