How to reset my JVC everio GZ MS120 BU - JVC GR-D850 Mini DV Camcorder

If you're experiencing issues with the menu buttons on your JVC Everio GZ-MS120 camcorder after adjusting the settings, there are a few troubleshooting steps you can try:

1. Remove the power source: Disconnect the camcorder from any power source, including the battery and AC adapter. Leave it disconnected for a few minutes to ensure a complete power cycle.
2. Reset the camcorder: While the power source is disconnected, press and hold the "Reset" button on the camcorder. The reset button is usually located in a small hole or recessed area and may require a small pin or paperclip to access. Hold the button for several seconds, then release it.
3. Reconnect the power source: Reattach the battery or connect the AC adapter to the camcorder and turn it on. Check if the menu buttons are now responsive. If not, proceed to the next step.
4. Connect to a computer: Use the USB cable to connect your camcorder to a computer. Once connected, some camcorders allow you to control and adjust settings through the computer's software or firmware update utilities. Try accessing the settings through the computer interface to adjust the display brightness or perform a factory reset.
5. Contact JVC support: If the above steps don't resolve the issue, it's recommended to reach out to JVC's customer support for further assistance. They can provide specific guidance tailored to your camcorder model and help you troubleshoot the problem effectively.

Remember to provide as much detail as possible about the issue and the steps you've already taken when contacting support. This will help them provide accurate and efficient assistance.
