Why does the green light come on but the unit doesn't light or charge?

Time to replace battery

Take it apart. The battery inside has corroded the wires at the terminals. Replace ends clean and put protector spray on them.

Hi, I'd suggest using a wall charger as they're able to provide more power to charge then a computers USB port. Often with camera's the USB port doesn't supply enough power so the camera doesn't charge at all.

Check the Capacitors on the Power supply board. They look like little soda pop cans. They all should be flat tops. If you see some buldging tops? They are bad and need to be replaced. Please use caution though Unplug the tv and discharg all large capacitors before proceeding. Cause even an unplugged unit the Caps hold a charge that can kill you.

The unit still,work?The battery when it low,the battery light turn yellow or red?Than when it fully charge it turn green?Just unplug the unit and use it dosen't matter,if the light don't turn off the light,that find.Or the battery is old and not taking full charged anymore that another resoan the charging light still on.

The green light indicates that the unit is already adequetly charged. If KNOW that it is NOT charged, but are getting a green light anyway, then the unit may need to be replaced.

The rechargeable batteries are no good or a connection in the battery holder is loose.

Sounds like it's time for new batteries.
