Jvc everio G power cord is broke

You want the AC adapter, not the charging unit. If there is sufficient undamaged cord, you can splice both the wires together and use the AC adapter.

Carefully identify the wires - one will have a raised rib or line printed on it. Strip 1/2 inch of insulation off each end of all wires. Matching the wire pairs, twist the stripped wires together. Fold the stripped wire back in line, and wrap the spliced wire connection with electrical tape. Do this for the other wire. Inspect you work to ensure the spliced wires are completely covered and do not touch each other. Wrap the entire spliced section in electrical tape and hook it up to the charging base.

Ebay has a selection of replacement ac chargers. Look on the back of the charging unit for the model number, and observe the voltage and current ratings.

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:

On the cors itself one side has either a white line or is ribbed. Just match up the correct lines and splice it back together. If you have them reversed, polarity is backwards and TV won't operate. If that doesn't solve your problem it's more than likely the fuse inside the TV where the cord enters the back.

Possible that the battery is bad as it does not have the voltage and current to switch on. So use a multimeter to check the charge on the battery. if the charge is low then you must replace, other wise it can also be related to a fault on the charging control circuit as it fails to connect the battery .

Try a camera store to see if they can help you, second option is go to www.jvc.com for customer support and ask for technical assistance they should be able to supply you with the cord or tell you the closest store available.

fix it!! with it unplugged, strip both ends of the chewed area to bare wire and then splice them back together. Wrap the splice with electrical tape!

Computer USB output does not provide sufficient power. Look on Ebay, buy a new charger

They sell external battery chargers for these for around 10 bucks at Amazon. Just pop the battery in the charger. Beware the battery itself can be worn down or dead. It also has protection circuits right inside the battery that can be blown (maybe a small fuse too). A new high capacity battery (3 times the recording time) is also at Amazon for around $25.

If your extended battery came with small cord the cord needs to be plugged into the battery and the camera DC outlet).  My Everio was doing the same thing and I did the above and it works.
