Re: 18-55mm lens won't zoom
I fix it!
This problem is due to bad design (I think)
The problem is cause of the guards/holder/stand bends a little the you turn the zoom.
I bend the guards just a little to the left.
This get the guards to stand straight then you "zooming".
Perhaps a little grease can help too, but what kind do you use inside a kamera?

Here are some troubleshooting steps that you can try that may (or may not) correct your problem. They only seem to work for less than 40% of the lens errors, but if the camera is out of warranty (or repair cost approaches that of the camera), they're worth that try. Some of the later steps do involve some risk to the camera, so carefully weigh your options before deciding to conduct them: And here's a video summary of the steps:
that error code indicates the the Lens of teh camera is already defective., In most cases if the lens is stuckout or stuckin camera will not stay On or It will not Turn On at all. For this case you need to call Tech support to send you camera for repair toll free 1 800 235 6325 extension 12
2) I do not understand your assertion that it automatically zoomed in. Zooming is a manual function. The automatic functions of your lens pertain only to focusing on of the subject so that your picture is sharp and ensuring that the correct amount of light is admitted so that you have a correct exposure.
3) Are you sure you were turning the zoom ring and not the f-stop ring? The zoom ring is labeled 200 on one end of the scale and 55 on the other. It is also the widest ring on the lens barrel. When you rotate it, the physical length of the lens will lengthen as you rotate it clockwise (viewed from behind the camera) and shorten as you rotate it counter-clockwise.
4) For reference, at 200mm the angle of view on your lens should be 10 degrees and at 55mm about 40 degrees.
This seems to be a common issue. Mine was stuck at what seemed like max optical zoom. When i would look in the lens I could not see the zoom lens. If you can not see your zoom lens and the optical zoom seems stuck I bet your camera has the same STUPID issue that mine has.
It was out of warranty and I figured I had nothing to loose so I took it apart to see if I could fix it, turns out I was able to fix it just by taking it apart and putting it back together!
Taking it apart is simple enough for the average handy man, if you do not have confidence that you can take it apart then do not attempt this repair.
Take off the bottom cover. Take off the Hard drive cover Now remove the three screws under the hard drive that hold the drive's plastic housing in. Remove the screw that is right under the record button, now the drive house should be loose. Disconnect drive cable from board and remove drive and housing. Take off the plastic piece that has the zoom button, be sure to gently disconnect the wire. Remove rear piece. That screw marked with an arrow on the bottom, do not remove it! Now remove the thin metal piece to expose the flat cable. disconnect flat cable from board gently flex it out of the way so you can disconnect the cable behind it. Once you have both disconnected remove the circuit board. unplug the flat cable on the back side. Now remove the front piece. At this point you are nearly there! Now remove the metal housing that holds the lens assembly. Once removed remove the lens assembly by removing the three screws.
If you thought that was bad, this next part will scare you. Make sure you are in a very clean room with no fans blowing. Remove the CCD from the rear of the lens assembly by removing the two screws on the back that hold it in place. Remove the foam and square lens piece that were behind the CCD. On the side of the assembly is a screw that holds the top cover in, remove it and gently pry off the top cover.
looking inside you will find the following: on the CCD side is the focus lens. in the middle is the shutter On the side farthest from the CCD is a zoom lens.
On mine the zoom lens was not close to the shutter If your zoom lens is not close to the shutter then you likely have the same problem as I had and you can fix yours! If not, you likely have some other issue :-(
To fix mine I turned it over and I loosened the screws that held the motor and shaft for the zoom lens. Then I slid the zoom lens as far back as it would go towards the shutter. Then tightened the zoom lens motor and shaft mount. Put it all back together, installed battery and bingo it's working again!
Why did this fix the problem? Well there is a little sensor that tells the camera that the zoom lens is near the shutter. Each time you turn off the camera it always puts the lens in that "home" position. If the camera is turned on when the zoom lens is not in this "home" position then the camera seems to assume the zoom is broken and you end up with the infamous JVC stuck zoom issue.
My guess is this problem is caused by any of the following: 1. Removing the battery while the camera is turned on 2. Dropping the camera while it is on or off 3. Battery going dead while camera is in use
Final thoughts before you get started:
1. If you are not good at working with tiny parts or electronics, I wish you luck because you will need it. Might be better off printing these instructions and taking them with you to a repair facility and paying someone more familiar with this sort of work to fix it for you.
2. The ribbon cables are removed easily. Each one has a clamp that rotates to release the ribbon. Some rotate towards the ribbon to release, others work the opposite. It is quite obvious looking at them which ones go what way.
