HELP PLEASE! jvc gz-mg20u "communication error"

by keprum2 / March 16, 2009 9:00 AM PDT

I have a JVC GZ-MG20U that is giving me "communication error" when I turn it on then it shuts itself off. JVC's dismal support site show nothing when I search the FAQ's. I have a new battery in it too. PLEASE HELP I need this camera for my wedding and I cant afford another one. Thanks everyone for reading this.

Fist off thanks for the assist. I followed the steps in the manual but still get the error. this is frustrating as hell and JVC says bring it to the service center. This cant be that big of an issue to fix. the camera worked just fine when last used about 5 months ago.

"This cant be that big of an issue to fix"... then you can continue to feel frustrated and not have a working camcorder.

I hope you get over it what ever it is. I'm not sure that this is a 'problem' in your eyes but it is to me. Please anyone if you can offer help to FIX this problem then I would appreciate it. If your going to comment on my frustrations instead then dont bother to post. I have a camera that worked fine and now it doesnt and If you cant help with a solution then it's ok. Anyone else had this problem before?

I see from the manual that it looks like the device needs repair. Time to ask all your friends to look around for another camcorder for the job.

Communicating Error
by kimbee2 / July 2, 2010 8:17 AM PDT

Don't throw it away yet! I ordered a high capacity battery from e-Bay, not JVC, hooked it up, got the Communicating Error. It's may be just your battery if your issue is like mine, as I put the regular battery back in and it operated just as normal. The new battery had a pigtail that had to be hooked in where the charger normally goes. Time will tell, but in my case, it is the battery. Don't know if it's defective or what the issue is but that's the issue in my case. So anyone reading this thread don't be throwing it away yet. Check the battery first.

THe answer
by naijaboy4u / March 6, 2013 9:35 AM PST

i found the solution. Sorry for replying late, i just found the video and the answer. Check the battery, it is probably coated. So the battery is not making good contact with the camera. So just take a knife or sharp things and scratch the place that makes contact with camera until you see little clear squares and plug it back to see if it works.
