Pentax Optio 555 - Fozen with the lens stuck-out

I have a Pentax Optio 555 (3 yrs old) that hasn't worked and the lens became stuck in the extended position for a couple of weeks. It happened when the battery was almost depleted. I turned it on, the lens sticked-out, and suddenly the camera went dead. Then, I charged the battery and put it back in. However, the lens never re-treated and the camera never worked anymore. Does anyone know how to repair this problem? Any place that can fix this camera cheaply? Please help. Thanks.
