There is sensor inside the unit that will detect dew. Moisture inside will cause the tape to adhere to the heads, causing damage to both the tape and heads. With the unit open, try pointing a hair dryer at it from a distance of about 12"-18". The warm air should remove any moisture. Please be careful NOT to aim really hot air into the unit.

If that does not resolve the problem, then either the sensor is defective or the connections to it are broken. The camera will err on the side of not functioning in order to prevent damage.

Keep us posted,

"Dew" sitting on my Video Camera


Dew Formation
What is “dew formation”?
When cold water is poured into a glass,
dew drops form on the glass. This clinging
of water drops is called dew formation.
When dew forms in your camcorder.
Dew will gradually form on the head drum
of your camcorder and make the video
tape stick to the head. This causes
damage both to the head and the tape.
When dew forms, recording and playback
may not function properly.
Dew is likely to form in the following
circumstances:
—When moving the camcorder from a
cold place to a warm place.
—When placing the camcorder in a cold
room which is then heated rapidly.
—When moving the camcorder outdoors
from an air conditioned room or car.
—When placing the camcorder in the
direct path of air
blowing from an air
conditioner.
—When placing the
camcorder in a
humid room.
How to prevent trouble.
When using the camcorder in a place
where dew is likely to form, allow the
camcorder and the video tape to
acclimate to the surroundings for about
one hour.
For example, when bringing the
camcorder indoors after skiing, place it in
a plastic bag.
1Be sure to tightly seal the plastic bag
containing the camcorder.
2Remove the bag when the air temperature
inside it reaches the temperature
of the room.
“Dew” warning feature
If dew forms, the word “DEW” flashes on
the screen, and the power will automatically
turn off in approximately 10 seconds.
Plastic bag
1If “DEW” flashes, remove the cassette,
leave the cassette compartment open,
and wait for a few hours to allow the
camcorder to acclimate to the
surrounding temperature.
2To use the camcorder again, turn on the
power after waiting for a few hours. Be
sure that “DEW” has disappeared.
3Do not insert a cassette while “DEW” is
flashing; this may result in damage to
the tape.
4Since dew forms gradually, it may take
10 to 15 minutes before the dew
warning feature engages.

Bypassing dew sensor on a Sharp VL-Z7 mini DV


- the solder joints to the DEW Sensor were "cold joints" which means that the solder joint is defective - is not a sound joint. This means that with temperature variation, the solder joint can intermittently separate and break the circuit, causing the DEW Indicator to come on and completely shut down the camera. The first problem I had with the camera was on a cold day, so it seemed to make sense.

Here is a picture from the perspective of the tape cover being at the top of the picture and the rest of the camera at the bottom. The dew sensor will be on your left.

go to:
http://omlets.tripod.com/sharpdew.jpg
Then, get a real slim soldering iron with a fine point. Open the tape cover and take the tape out. Get a strong light to shine down into the mechanism.

If your camera is like mine was, you may see a brownish material on or around the solder joint - this is flux used in soldering which was applied too heavily, and not heated long enough to burn off. The joint therefore doesn't quite connect the dew sensor to the terminal post - depending upon heat/cold ambient conditions, sometimes it makes contact and sometimes it doesn't .

Heat up the soldering iron - make certain the point is tinned (has a thin film of solder on it). Carefully just touch each solder joint for a couple of seconds - just enough for it to melt, and then quickly remove the soldering iron. You don't want to leave the iron in contact with the solder too long or it may melt other insulation around the terminal. This all probably sounds more complicated than it really is - but it really is just a 5 minute operation. If you've not done much soldering, and feel uncomfortable about trying it, you may want to take it to a radio, tv or computer repair shop and ask them to do it for you.

Flashing "DEW" Indicator shutting down the viewcam


I don't know if this will help, but when I leave the camera open with no tape in it for a day or so, "dew" goes away. Now I just store it open without a tape in it and have never had this problem again.

Hope this helps.

Dew


Model: VL-Z800 Sharp ViewcamZ

I was in Shanghai in Dec 2008 over Christmas and I experienced the 'DEW' problem. The cassette tape door would not close either. I did not experience this before even after 2 years. I suppose the cold & the rain water causes the dew to accumulate in the CAM.

Solution.
I did the reset by taking out the small tiny battery situated just above the big battery. The small battery has a cover. Pull it up & Get the small battery out and the whole camera resets. Re-entering the date & time is the only inconvenience. After reseting, I could use it again, but not for long as the problem comes back. When I came back to Malaysia (Temp 32-34 degrees celsius), the DEW problem disappappers.

You could also try this method to get rid of the dew. Buy a small sack of rice. Yes rice, the uncooked ones. Cut open a small opening just big enough to put your CamCorder into the sack. If you do not want to get your CAM dirty, wrap the CAM with tissue paper. Close the opening with a musking tape and leave it a few days. The dew should disappear from the CAM. It works for mobile phones too when it is accidentally drop into water. Of cause you should not switch on the mobile when it is still wet. It will self distruct if you do. Try the rice solution for a week before you on your mobile.

Dew detected on DV-203


I bought my 203 2 years ago-same problem. I FOUND THE SOLUTION! Might sound stupid, but I found it online, tried it and it works! When you get the "Dew Detected" sign on the screen, remove the battery, give it a good palm hit on the bottom where the battery sits. Hit it a couple good times, put the battery back in and voila it will work guaranteed! I thought it was dumb at first, tried it and it works, hell it works everytime. The blow dryer, plastic bag trick dont work because its an electrical error, not actual dew.

Dew


the only thing I can suggest is resetting the camera by removing the tape and closing compartment... then remove batteries and let sit for 3 minutesturn on camera and insert tape, you should get it to work... my cam does the same thing, I use it and right when something important comes up I get hit with the dew warning.. apparently its a faulty sensor inside the camera usually I can override it by resetting the camera. I hope this helps in any way, i know the frustration with these damn camcorders, it will be the last dv cam I buy from sharp
