I have an old Panasonic miniDV camcorder (PV-DC252D). When I turn it on, the message on the screen says "press the reset button". After I do that, the message on the screen says "needs to be serviced". The entire time this is happening, camcorder is running loudly and I cannot open/eject the cassette. I no longer want the camcorder and plan on transferring my mini DVs to disc, but I just want the cassette that is now stuck inside. Any advice on removing it manually?
