You have a lens problem. Sure it can be fixed but be sure to get an estimate first.

i had the same problem a while back. I fooled around with my camera lens a bit and it turned out that one side of the lens was sticking out a bit. I pressed down on this and pushed the power button and it worked. The next time I turned it on the same thing happened but if you keep doing the same thing it should work.

Hope this helps!

If the lens is retracted, hold up the camera to your eye and look at the lens. If you see one end sticking out a little bit, push that side in and press the power button. It should work.
If the lens isn't retracted, push the lens around until it is in its regular position. When you press the power button, it will retract and come out again and should work fine.

Hope this advice helps!

If the lens on the camera is stuck out, look to see if it's a little crooked. If it is, try to gently straighten it. If it still won't retract, try to gently push it in as you turn the power on.

Just had this happen to my L100. First, take out the battery and wait a couple hours for everything to cool down and discharge. Then place the battery back in. Then plug the USB cord into the camera and PC. Then turn the camera on and it should be okay. Just worked for mine.

If it won't turn on (the green light blinks and it beeps 3 times) push and hold the 'power' button and the 'play' button at the same time for a few seconds - it worked for my S730. Good luck!

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 :(

If your lens is open and the camera turns off after those dreaded beeps, I have a fix for your problem. Basically, for this model of camera, the lens first pushes out a bit and then it retracts into the camera. Well, my lens got stuck on the pushout and it prevented the camera from turning on. I used some finger pressure and wiggled the lens a bit. Then I turned it on and it retracted to where is was supposed to be to take pictures. Then I turned it off and it retracted into the camera. Problem solved!

OMG! so i read all these suggestions and nothing worked or i was just confused..tried the tapping thing but didnt work..so i finally just kept twisting the lens and pushing it in and out..it doesnt really move but i was angry and hoping this was doing something..i turn my camera back on a IT WORKIN AGAIN:) im so happy becuz i was so pissed that i had to buy another camera but i suggest trying this method if the table tapping dont work..OH and my lens didnt look crooked at all so if urs look straight and stilling doing stupid beep thing ,,,try this!
