The mechanism got stuck. Open the cassette compartment screws and apply external DC to the Power input and eject the tape. If this is not possible refer to a skilled technician. If you need the service manuals and mechanism for replacement write to us.

The main chassis has a problem with it its very easy for them to break when that happens it needs to be replaced sorry if you need the tape i can post back how to get it out you would need to take it apart but its easy

SOURCE: push the reset button

let the camera sit alone for About 20 min,so that the camcorder automatically turned off. I turned it off, then back on and did not receive the reset button prompt.
if that doesn't work unplug the battery and all power and plug back in.

I was having the same problem. I just gave it a few gentle smacks from every angle possible and it quit acting up.

This camera needs to have the battery recharged in order to remove the tape.
