Sony DSC-P10 lens covers won't open

The system control board has shut the camera down to prevent damage, the lens housing will need to be replaced because you have two problems, one the lens is jammed and second the shutter is open, the cost to repair will be equal if not more than a new one.

Lens block is faulty you must replace it with a new one

Mr anil there seems to be a problem with the sensor linked to the lens guard. Try to move the lens cover a few times and try to open the cover as much as possible just to initiate the sensor. If this does not solve the problem then you have to show it to a mechanic.
Regards.

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.

There is probably no user solution, it seems that optical lens vibration stabilizer is wrong/damaged, the only solution is to replace it.

Seems your camera Sony DSC-T1 got bad ccd imager problem, as camera does not show live image to record and shows previously stored pictures fine in playback mode.
Sony will repair it free of cost. Click Sony CCD Imager Support for details.

Never buy SONY dsc-t300 again

The gearing on the lens is probably damages from the drop. You have two choices:
1. Send it in for a repair (which will be expensive) and claim from your insurance. If it is uneconomical to repair, your insurer will probably pay for a replacement camera.
2. If you're not insured, it may be cheaper to just buy a new camera rather than pay for a repair to a 4(?) year old camera.

About the LCD turning white, it an indication of a defective LCD, About the lens stucked-up its a lens problem, It will be solved if the LCD and lens assy's be replaced. thanks
