I dropped my camera and now it turns on but the lens dont move and the screen wont stay on

Since there is nothing you can do to fix this at home you have 2 choices, replace the camera or send it back to the manufacturer for exchange (very expensive)

Lens errors are fairly common. Usually it's sand or grit interfering with the lens extension mechanism. Or the camera's been dropped with the lens extended. Or the camera has been powered on, but the lens had been blocked preventing its extension. Or the battery ran down with the lens extended ...
Here are some troubleshooting steps that you can try that may (or may not) correct it. They only seem to work for less than 40% of the lens errors, but if the camera is out of warranty (or repair cost approaches that of the camera), they're worth that try. Some of the later steps do involve some risk to the camera, so carefully weigh your options before deciding to conduct them.

I have this same problem, but I never dropped the camera. I got it 2 months ago.

The lens has probably got something in the retraction mechanism that is stopping it retracting. This can be something as simple as sand or grit or as a result of a drop or knock. In most cases the camera will need to be stripped apart to remove the lens assy before it can be repaired. This is best left to a professional camera repair shop.

Your lens is not fully extended. try wiggling it a bit and then turning it on. problem will get solved. my 3 year old dropped mine and the same thing happened.

FOLLOW this procidure open the camera then rotate the lens and set it like it was before

Met the same problem. I disassembled camera and found a lot of sand in lens transmission. I couldn't move lens even by hand. It was strongly jammed. I had to disassemble lens block completely to remove all sand. Now camera fully functional.

Ihave the same problem. Its annoying. When you turn it on does it make a buzzing noise? Cause that's what mine does. Except I never dropped my camera. It just goes to the Polaroid screen and then turns off. I'm wishing I wouldve bought a different camera :( Sorry I can't help..

your lens are stuck! did you drop the camera? you need to get a repair on the lens
