Casio Exilim lens stuck half out.
Do these step by step
1.Remove the batteries from the camera, wait a few minutes. Put a fresh
set of batteries back in (preferably rechargeable NiMH 2500mah or
better) and turn the camera on.
2.Remove the batteries, then remove the memory card. Then install the new
batteries, when you turn it on it should come back to life. Error E30
means you don't have a memory card installed, so turn it off, slip in
the memory card and turn it on one last time.
Insert the cameras Audio/Video (AV) cable, and turn the camera on. Inserting this cable ensures that the camera's LCD screen remains off during the start process. Thus extra battery power is available to the camera's lens motor during startup. This extra power can be useful in overcoming grit or sand particals that may be jamming the lens. If the AV cable doesn't fix the lens error by itself, consider keeping this cable installed while trying fixes 4, 5, and 7 as a means to provide extra help to these fixes. But note that I DON'T recommend keeping the cable installed during Fix 6 as you may damage the AV port while tapping the camera. Reinsert the cable only AFTER tapping the camera.
4.Place the camera flat on its back on a table, pointed at the ceiling.
Press and hold the shutter button down, and at the same time press the
power-on button. The idea is that the camera will try to autofocus
while the lens is extending, hopefully seating the lens barrel guide
pins in their slots.
5.Blow compressed air in the gaps around the lens barrels with the idea
of blowing out any sand or grit that may be in there jamming the lens.
Other variations include blowing with a hair dryer in “no heat”
setting, or sucking the gaps with a vacuum.Be careful
the following steps are littile bit dangerous.do it at your own risk
6.3Repeatedly tap the padded/rubber usb cover on a hard surface with the
intent of dislodging any particles that may be jamming the lens. Other
variations include hitting a side of the camera against the palm of
your hand. A lot of people have reported success with this method.
HOWEVER, there is also some potential for damaging or dislodging
internal components with this method, such as unseating ribbon cables,
or cracking LCD screens.
7.Try forcing the lens. More people have reported success with this
method than with any of the other methods. HOWEVER, there's obviously
some potential for damaging your camera by using this method.
Variations include gently pulling, rotating, and/or twisting the lens
barrel while hitting the power button. Attempt to gently straighten or
align the barrel if it's crooked or twisted. Another variation includes
looking for uneven gaps around the lens barrel, and then pushing on the
side of the lens barrel that has the largest gap (note pushing the lens
barrel all the way in is NOT recommended as it may become stuck there).
While doing any of the above, listen for a click that indicates that
the lens barrel guide pins may have reseated in their guide slots. If
you hear this click, immediately stop and try the camera. The following
photo illustrates unseated guide pins that would cause a lens error.
