Same kinda thing but...

Most likely what is wrong is that the lens cover has become sticky, or clogged. Have you spilled a soda, etc. on it recently?
The best thing to fix this would be to aim a canister of compressed air directly in-between the lens fover and the lens, blowing anything out. If this doesnt work, then manually push the cover back with your fingernail and try again with the compressed air.

hi this is ajay i have nokia n82 .. mobile . the problem is camera is not working some times .when i open back lens cover the camera start but is show black screen .iin some times .. and another bug is buletooth . when i on buletooth it says unable to perfom plz helpp meee .....

your laser lens of the dvd doesnt work thats why it doesnt read the disc the same thing was happening to me so u can open it and look if the thing where the laser lens is at is not stuck or your lens they wont work anymore.

Everytime I try to turn it on, the lens comes out for about a second, the camera beeps 3 times, the lens retracts and the camera shuts off. The battery is completely charged and the camera is only 4 months old. HELPP :(

you might have an engine problem...im going thru sort of the same thing right now....it kinda makes a rumbling motion when your slowing down and feels like it wants to completely shutoff as you come to a stop...i dont really know if there is anything that can be done, try a tune up first but if that doesnt help it then just deal, it a nusance but hey at least it still runs.....

time for a replacement camera...as the repair wouldn't be to expensive to consider.  Use your wrist strap

try turning it on and when turning it off push the lens

Try this: Power the camera on then gently push on the lens while hitting the power button again so that it will try to retract the lens. but be gentle as you could damage the camera worse.
if your interested in having it fixed for around 120 or more than dont try anything and just take it to a repair company.

if that doesnt reset the camera then you can try taking the batteries out for a couple day and then put some lithium batteries in it if it takes aa's that is. They have a little higher voltage than some batteries and while sometimes give it a little more push to get things going. Leaving the batteries out would let the camera forget its memory. If you had the camera stored without batteries then don't worry about trying to reset it as that would have already happened.


Let me know how that works or if you need anymore help,

My friend had the same issue, and so did I. Maybe this would only do worse to yours, but it actually fixed my issue. When you turn the camera off, the lense should start to tuck in right? Maybe try giving a little push to help it out.

Well put it away somewhere warm for another month with the battery out.

But I have a feeling that the camera has died
Nothing for you to repair in side so you wont beak anything by taking it apart for curiosity sake.
