Camcorder is dead, how to dismantle to get cassette out.

To open and remove a stuck cassette from a Memorex 16-854 camcorder, you will need to follow these steps:

1. Locate the cassette compartment on the camcorder. It is usually located on the side or back of the camcorder and is marked with an icon that looks like a cassette.
2. Open the cassette compartment by pressing the release button or lever.
3. If the cassette is stuck, you may need to gently wiggle it or use a small tool, such as a pen or paperclip, to gently pry it out of the compartment.
4. If the cassette is still stuck after trying these steps, you may need to use a little more force to remove it. Be careful not to damage the camcorder or the cassette.

I hope this helps! If you have any further questions or if you are having trouble removing the stuck cassette from your camcorder, don't hesitate to ask.

unscrew the bottom or side one and take that cover plate off.

Moisture condensation has occurred.
Remove the cassette and leave your camcorder for at least 1 hour to acclimatize. (p117)

On p117
-------------------------------------------------
If your camcorder is brought directly from a cold to a warm place, moisture may condense inside your camcorder, on the surface of the tape, or on the lens. In this condition, the tape may stick to the head drum and be damaged or your camcorder may not operate correctly. If there is moisture inside your camcorder, the beep sounds and the [picture of water drip] indicator flashes. When the [end tape icon] indicator flashes at the same time, the cassette is inserted in your camcorder. If moisture condenses on the lens, the indicator will not appear.

If moisture condensation occurred
None of the functions except cassette ejection will work. Eject the cassette, turn off your camcorder, and leave it for about 1 hour with the cassette compartment open. Your camcorder can be used again if the [water drip] indicator does not appear when the power is turned on again.

Note on moisture condensation
Moisture may condense when you bring your camcorder from a cold place into a warm place (or vice-versa) or when you use your camcorder in a hot place as follows:
- You bring your camcorder from a ski slope into a place warmed up by a heating device.
- You bring your camcorder from an air-conditioned car or room into a hot place outside.
- You use your camcorder after a squall or a shower.
- You use your camcorder in a high temperature and humidity place.

How to prevent moisture condensation
when you bring your camcorder from a cold place into a warm place, put your camcorder in a plastic bag and tightly seal it. Remove the bag when the air temperature inside the plastic bag has reached the surrounding temperature (after about 1 hour).

I just solved my own problem by disassembling the camcorder until I had access to the little motor which operates the eject mechanism. It sits on the corner of the mechanics subassembly, close to the cassette. By applying about 3.5 Volts DC from a regulated power supply to the two motor contacts, it started to operate (test which direction it needs to go by trying both polarities) and lifted the cassette out of the play position and ejected it. Only since the tape was still wound around the drum, I had to use a thin tool to turn the cassette hub in order to tighten the tape a bit. Then the protective cover of the cassette closed and I could slide the cassette out of the slot by hand. Bingo!

most cameras of this type have a series of cogs inside that u can manualy turn by hand or by using a small screw driver,wich will inturn open casset mechanism you need to have a good look and you will suss it out i have done this many times with camcorders dvd players and vcrs, take care andy hope this helps
