Question about Sharp VL-Z5 Mini DV Digital Camcorder
Whenever the camera is started it just shows a blue screen saying "DEW"... I'm unable to do anything, also tried to keep the cam in mild sunlight so as to dry away any moisture, no idea wat is wrong, please help
I had the same problem on a Sharp VL-Z3U
This was what worked for it & yours may very well be the same thing:
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.
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.
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.

I had this same problem with my vl-z5.This worked for me. It was quick and my favorite, cheap. To fix it, first take the tape out of the camera. Look at the tape and see where the contact points are. Then look inside the camera for the contacts. They will be in the same position to line up with the tape. I just used some alcohol from an alcohol swab (Walmart for $1.15 for a box ) on a q-tip and rubbed the contacts clean with about 5 passes over them. I gave it a minute to evaporate and replaced the tape. Everything works fine again. Quick and easy, and no more DEW!
