It is possible that the dew sensor is faulty or more likely that the connection from teh sensor to the rest of the camera is faulty. This unit will require repair. If you can soler, you may be able to resolve this. I'll look up your model to see how bad the access is to the sensor.

For Sharp (at least vlz8xx series)
It seems that the due detector can suffer from bad soldering or soldering alteration after few months of use.

1. The (ideal but uneasy) solution consist to fix this solder by making a clean new one, I personally did it, and it worked for a few months without a problem anymore ; but then it came back again.

2. The other solution consist in short-circuiting the dew detector to eradicate the problem.
Of course, it will also mean that when real dew will happen you may use the video tape recorder when you shouldn't, but at least you should not see the problem coming back again some months later.

To know more about this dew detector circuit and how to fix it the way you want go there:

a zoomed picture of where to fix the detector can be found here:

PS: variants that worked for some of us like putting a magnet for a minute on the sensor seemed to work for 2 testers.

Hope this will help as it helped me,
Good luck,
Fabien.

"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.

Shut down "dew"


This happens when you take camera from cold(er) environment to warmer environment, dew forms on the recording head, so as a precaution the unit locks up. The solutions is to leave the unit switched on and wait till the dew incator goes out( can take up to an hour) I found this out when on holiday, i would go from an air conditioned room to bright sunshine and it happened all the time.

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


I had this same problem, and believe it or not, it is very simple to fix.
The fault is a dry joint on the dew sensor circuit.
This can be fixed permanently with a soldering iron, or if you don't want to kill the camcorder you can do a temporary fix each time the message occurs.

If you remove the tape and look down inside the camcorder, towards the front, next to a green circuit board, you will see two small blobs of solder with a wire running from each.

The image below shows the most likely position that needs either soldered or pushing in with a screwdriver or other fine metal device. You can remove the batteries first, for extra safety.061fb70.jpg

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.
