Not quite certain how the problem actually manifests itself.
If the sliding cover just will not slide back to expose the lens and switch the camera to capture mode then it might be impact damage due to being dropped. However it might also be due to the mechanism seizing up through lack of grease or jamming due to the two small spring loaded bearings that give the mech its snap locking action.
If the cover moves freely but the lens does not extend and the camera does not go to the capture mode of operation then.
You are probably suffering from the most common fault with the
MJU 300/400 range of cameras that the black
plastic armature operated by the sliding action becomes loosened from
the case resulting initially in the cover becoming sloppy and causing
the lens to keep closing erratically. More importantly the plastic
armature which is positioned to operate a tiny Surface Mounted switch
can cause the fragile plastic 'nib' to break off. It is this switch
that in effect turns the camera on. If this is what has happened, it is
the most common fault, there is very little that can be done as a DIY
repair unless you have access to speciallised SMD soldering equipment,
experience in this type of repair and most importantly a source of
supply for the SMD switch. I have as yet been unable to identify the
type or supplier myself. The alternative is to take the camera to an
authorised repair shop. This is the expensive route but you might be
able to keep the costs down by making it obvious that you know what the
fault is etc.

Re: Lens cover doesn't open when switching on
If you've recently dropped the camera you may have damaged the lens
tube (housing) or jarred the zoom mechanism off of its track. Either
one of those problems will require professional repair. If it hasn't
suffered from a drop, your problem may be due to weak/worn out
batteries or corrosion on the
battery contacts inside the camera
which can prevent the full power of the batteries from flowing into the
camera. Try this free fix before you do anything else: remove the
batteries and wipe the camera contacts firmly with
a dry cloth (heavy corrosion may require cleaning with a wire brush,
steel wool, or sandpaper). Remove any residue that may have fallen
into the battery compartment during cleaning, then wipe both ends of
the batteries and place them back in the camera. This cleaning clears
the problem about 90% of the time. If it doesn't work for you, your
batteries may be to weak/worn to properly power the camera, or the
camera may require professional repair.

You need to go in and physically open the lens cover. 1. take out batteries 2. remove memory card + the small phillips screw. 3. remove the 3 remaining exterior screws. carefully with a small flat tip screwdriver pry the plastic halves slowly. eventually they will come apart. 4. at the bottom remove the small ribbon cable. 5. disconnect the mini motor wire, black and red. 6. unscrew the motor drive for the lens cover and then open the lens. 7. purchase a new lens cover motor. 8. If your screen still says turn off , then press menu and delete some files. good luck ! Work Slowly and carefully and ground your hands to a pipe somewhere before working on the unit. the static electricity could ruin the circuits !
I have just had exactly the same thing on my daughter's NV3.
In this case the lens cover would not open but if you power on the camera with you finger on the display button you can view stored images.
If the lens cover is jammed you need to open the casing and maybe take the lens cover assembly apart. You need a very small cross head screwdriver (No.00 should be OK). There are 5 screws in total, 4 screws on the outside of the case (3 plus1 under the headphone socket cap) and 1 inside the battery compartment. You need to remove all 5 to remove the camera front casing. There are some retaining springs top and bottom on the front cover, gently prize off to reveal the lens cover assembly.
Check to see if the lens cover will operate by switching on and off - if it works then the camera front casing is preventing it from opening and is probably bent out of shape. A little careful bending back into shape should resolve the problem. If it still does not work with the casing removed, read on.
This is the tricky part. There are two extremely small, black retaining screws to the left hand side which hold the assembly onto the lens cover motor. Remove these screws and the front of the lens cover assembly to reveal the lens cover and the back plate of the assembly.
Lift off the lens cover and switch on the camera. If the motor is still working, you will see a short black peg move from side to side as you turn the camera on and off. Thoroughly clean the lens cover and assembly, remove any obstruction and replace the lens cover making sure you locate the hole in the lens cover over the motor peg (described above).
The motor is magnetic and will attract the screws away from their holes if you replace the assembly front straight away, so when you replace the front of the lens cover assembly, place the screws in the correct holes before lowering it into place and then screw onto the motor/assembly back.
Test that the lens cover opens and closes and replace the Camera front cover taking care not to bend it too much - if this becomes distorted it can stop the lens cover from operating resulting in the same problem.
The problem is that the lens has become stuck in the barrel. There are some DIY solutions you could try, but the
probability is that you will have to get it fixed by a professional.
these at own risk as it may further damage the camera.
try connecting your ac adapter or usb cable.
Try holding the
shutter button while switching on the camera.
Look at the lens ,
and if some of the lens 'circles' is misaligned or not concentric then
try wiggling it (while holding camera lens down).
pushing or pulling the lens when it extends but this is risky as it may
cause the lens barrel to slip out of its guidance system.
way to do this is to place the camera lens down on a hard surface and
then power it up. Be sure to use a soft cloth or something similar as to
not scratch your lens or casing. Let the lens push the camera up and
down a few times and sometimes the little resistance provided by the
camera is enough to get things going again.
Try hitting your
camera near the lens on the body with the soft tissue on the palm of
Other than that , I would take the camera to a repair
center for a evaluation to see if it would cost more to repair than to
replace the camera.
If it is still under warranty I would suggest
you take it in before trying any of these steps and remove any
off-brand batteries or accessories as some stores are really fussy about
warranty repairs on camera's with non-brand accessories.
maybe this works: turn your camera on in play mode (if you have play button press it to turn on camera) and if your camera hase a shoot-play switch select play mode and then turn your camera on.)
repeat this until lens goes back.
I hope this works...
first check the iris of the camera if it is
opening,you will see this when you look inside the lens of the camera
when you turn on and off the switch at camera mode if the iris is
opening....if the iris is ok the second problem may occurs of your
camera is the ccd image sensor....
the problem of your camera is the ccd image sensor...better go to the sony service center for replacing the image sensor..i know it is free for replacing that sensor cause that is one of the model that sony recall produc and the cover not open error message is a poor contact of the lens cover switch...
There is a workaround for this problem, when the lens cover is open press down on the area of the lens cover on the "s" of Olympus. This can operate the switch that opens the lens etc.
The long term fix is to remove the lens cover by removing the 2 screws at the base of the lens cover, take the lens cover off and gently clean around the switch which is behind the "s" of Olympus when the cover is on. I found that the grease/oil Olympus had used on the switch attracted dust etc and by cleaning this off the camera began working.
Be careful when taking the lens cover off, there is also a very small metal plate that separates from the lens cover - don't lose it.
Does the play back show any of the pictures you have taken before? are you sure the little lens cover is opening? there is a shield that closes down to keep the lens protected from debris and finger prints. Sometimes they can get jammed and not open. Tap on the front of the lens see if it opens.
Switch it to auto mode if its not in auto mode.
