Help before I take my camera in for service

[gregzz4]

I have a point and shoot that has been awesome for 5-6 years. It was top of the line new. I want to keep it. It has numerous settings for tank stuff, and has been our staple camera on trips. Fits in my pocket, takes 1080p movies in stereo; panorama, etc etc. Great camera. Was $300-400 new.

Now it suddenly takes blurry pics. On it's own it won't focus.
It will pretend to focus, but the resulting pic is blurry.

Before I take it in for servicing etc, any thoughts?
