Avr 120 Keeps Turning Off

1. Check for overheating: Make sure that your AVR120 has proper ventilation and isn't overheating. Overheating can cause the device to shut down as a safety measure. Check to see if there are any obstructions to the vents and ensure that it is not placed on a surface that can block air flow.

2. Check the speaker wires: Make sure that the speaker wires are properly connected and aren't damaged. Loose or damaged speaker wires can cause the receiver to turn off to prevent damage to the system.

3. Reset the AVR120: Try resetting the device to its default settings. To do this, turn off the receiver, press and hold the "Surround Mode" and "Tuner Preset +" buttons while turning the receiver back on. Hold the buttons until "Reset" appears on the display.

4. Update the firmware: Check if there are any firmware updates available for your AVR120 and install them. An outdated firmware can cause unexpected behavior.

5. Check the power supply: It is possible that the issue could be with the power supply. If the above troubleshooting steps do not resolve the issue, it might be a good idea to contact Harmon Kardon support or a qualified technician to take a closer look at the power supply.

NOTE: If none of the above steps resolve the issue, then it may be necessary to have the device looked at by a professional. Contact Harmon Kardon support or a qualified technician for further assistance.

Hope this helps!!

1. Check the power source: Make sure the AVR 120 is plugged into a reliable power source, and that the outlet is functioning properly. Try plugging the device into a different outlet to see if the problem persists.
2. Check the ventilation: The AVR 120 may be overheating if it's not getting enough ventilation. Make sure there's enough space around the device to allow for proper airflow, and check that the ventilation slots aren't blocked by dust or other debris.
3. Check the speaker connections: Loose or faulty speaker connections can cause the AVR 120 to shut off. Check that all speaker connections are secure and that there are no frayed wires or other damage.
4. Reset the device: Try resetting the AVR 120 to its factory settings by following the instructions in the user manual. This can sometimes resolve issues with power cycling.

If these steps don't resolve the issue, it's possible that there's a problem with the device's internal components. In this case, it's best to contact a professional repair service or the manufacturer for assistance.
