Question about JVC Everio GZ-MG30 Camcorder

1 Answer

Shut down "dew"

I have a Sharp camcorder which quite often when in the play mode displays the word "dew" in red then shuts down. This is consistent with the camera not allowing me to load a cassette into it. When the Dew message comes on it does not allow me to inster a cassette into the slot ejecting it at each attempt.

I would like to know what causes this malfunction and how I could possibly cure the defect>

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.

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.

Dew light


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. 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. When ?DEW? flashes, remove the cassette,leave the cassette compartment open,and wait for a few hours to allow the camcorder to acclimatise to the surrounding temperature. To use the camcorder again, turn on the power after waiting for a few hours. Be sure that ?DEW? has disappeared. Do not insert a cassette while ?DEW? is flashing; this may result in damage to the tape.

Dew


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.

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.
