Sony digicam problem

Hi guys, i have a current problem on my sony digicam.

heres the problem (ill include the ref down the post)

: the camera lens unfolds and folds like 3-4 times, then closes and says an error message : turn off the camera and turn it on everytime i turn it on.

I tried taking the battery off, charge it and then put it back thinking it was the problem but it kept doing it.

I turned it on yesterday, and it was ok but im afraid that was pure luck.

if you got any idea on how to fix it or why it does that, feel free add me pls. thanks !!!
