Oprio 430 RS problems

Our Optio 430 RS doesn't start up anymore: after pushing the start button the lens comes out, the camera makes a soft rattling noise and the lens goes in again. The camera went back to Pentax and was repaired. Now, three months later, the problem is back.

Anyone with a clue?
