On the camera Samsung WB500 (aka HZ10W) broke a round pen zoom in/zoom out. Namely, the longer return to the center position, which is pretty much hindered closer to the desired length.


Open it and look what happened. To analyze this technique, you can unplug the battery and memory card, unscrew the screws all the little body, they are located near the joints of the body from the bottom and sides.



Unscrewed the screws, remove the body. carefully with a large capacitor, it can be charged! It is better to defuse the resistance of the order of kilohms.



We proceed to remove the top panel, it is also fixed with screws. Unscrew the screws at each end.

One screw on the screen. Disconnect the two flexible loops: one simply pulled out, the other holding a clip.

Then remove the microphone from their seats, as the wires from them go to this panel. The panel can be removed.


Now we get to the defective item. It was spring and the two antennae that returns the lever to the center position. She broke off a mustache, making it ceased to function. It was hidden behind a small metal piece resembling a triangle, which was secured with a screw.
There was nothing to replace it, so we had to invent. From a piece of thin steel wire was made similar to a spring. Not as smooth and neat as factory, but is able to perform its functions.

Install the new part in place of the old.



The only drawback was that because of its shape was pretty hard to install the spring in place, and even tie holder.

Check whether well does the new spring to finish, if necessary, collect the camera in the reverse order.
