L can´t turn on my gz-mg50 camcorder, even with battery or ac adapter cable.What´s wrong ?

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.

Check the specs in the manual to determine the voltage/polarity (may also be next to the plug input on the camera) is the same and you may be able to use a generic adapter like those you'll find on Amazon for JVC GZ camcorders like this:

2A AC Wall Power Charger Adapter Cord for JVC Everio GZ E306 AU GZ E306 BU

hello, does it show any error code before is shuting down?

Only use the separate adapter. DO NOT PLUG IT INTO AC DIRECTLY!

Google AP-V17e and then you will find the adapter.

Camcorder has charging circuit but it could go defective. The repair would be costly so in this situation, you can purchase stand-along battery charger for around $20 and charge the batteries independently. Make sure all the contacts are cleaned and camcorder is working with direct ac adapter. Good luck -James. for furnter assistance by email, go to www.camerarepairjapan.com

Replace the CCD Base Assy.

I would first check the audio heads. Try a cleaning tape. If the tape fails to resolve the problem, have the unit cleaned professionally.

Your battery is probabily uncharged or disconnected. Try taking the battery out and putting it back in. Then charge it (by plugging in the AC adapter) until the green activity light stops flashing. If this does not work, your battery is probabily dead. Did you short it out? Or perhaps it is old. Li-Ion batteries (the kind used in these machines) lose their ability to hold their charge in a few years - even if they're not in use! So, if your battery is 3 or more years old, try considering a new battery.
