Question about JVC Cameras

4 Answers

JVC Everio GZ-MG27U 20GB HDD Camcorder has a problem that it only will work with AC adapter plugged into the camcorder. I have two batteries, one has a full charge of 7.7vdc indicating a FULL charge, the other has almost no voltage indicating no charge. When I use the good battery, the unit starts up when powered on, then shortly shows a camera - - - - battery on display and then goes to "communication error" and shuts off. I found that the connection at rear of camcorder labeled as the " " voltage point has no voltage on it at all with the AC adapter attached to the camcorder. This indicates to me that it will NOT charge a battery anymore. The "C" contact has about 3.09vdc with the camcorder in OFF mode, and no voltage in the Review or camera mode of the power switch. The "T" contact has 2.91vdc in any of the mode settings for the power switch. If I have the AC adapter attached, and a battery (good one) attached, the camcorder works fine. However, when I disconnect the AC adapter, the battery will not operate the camcorder by itself, and you briefly see a battery display on the screen but it shows low battery, and has a RED outline just before it loses all power. I believe the " " connector but have a broken wire somewhere behind it inside the unit. Can you confirm, and tell how to resolve this problem?

    The first response didn't really answer my question. I see my message shows a bunch of " items where I was trying to show the various connection contacts as they are labeled. The + is the one I was saying should be the +7.6vdc, the C is the contact that I read a voltage of +3.09vdc with the power switch in the OFF mode, and the T is the contact that had +2.91vdc on it in all mode settings of the power switch. This is with the AC adapter attached to the unit. I basically don't want to have an outrageous repair for a 2-year old camcorder, but was trying to confirm whether or not my suspicions that there may be a broken wire on the inside area of the camcorder for the + contact so it will not even charge a battery anymore, or accept the battery's own voltage to thus run the camcorder. If I really need to send it in, then yes, I would need to know where a repair facility is nearby to Rialto, CA, and also an estimate of repair costs if I were to chose that route. I believe I may tools to fix it if I am careful, as I was a electronics technician in my working years.



    Thanks, Steve

As far as i understood the problem

you need to replace the old battery which is not charging,

please dont use batteries of unequal charge in the camera operation. this will lead to problems from battery leakage to problematic accidents.

dont ever attempt to use batteries of unequal charge.

because i personally did it once and lot of oil like liquid got spilled from battery and spoiled the battery lid and the memory card slot.

    your idea also seems acceptable. there may be a disconnection between the units positive lead.

Better you can use a separate charger to have battery fully charged.

Communication error appears in harddrive camcorder JVC EVERIO GZ MG330A , battery doesnt work


Check your battery contacts and camera's battery terminals for some dirt. If not from there, your battery needs replacement. When buying new one, test it first before leaving the store, its because even new one(old stock) might have the same problem. Good luck

No power to camcorder


It is the internal circuitry that has to deal with powering the camera with the battery. You will want to follow this link and locate the nearest service center and have it repaired.
