Olympus FE-230 My daughter took this camera to the shore and got sand in the lense area. When you power it on, the lense wont' come open. You can hear it whirring like it wants to open, but it can't due to the sand. Any recomendations on how to fix this without having to go to a repair shop and pay god knows how much. ???? Help!

This sounds real familiar; I think I may have just responded to a post from your daughter -
This is what I suggested:

If the batteries are a common type, install them into another device to see if they really are still OK or buy a cheap digital multimeter or battery tester.
The latter can be bought at the chain hardware stores or Radio Shack and draw some current to lightly test the load capabilities of them.

These batteries do fail to a short (act like a piece of wire); NICads are the worst but lithium ion and NiMh can fail as well.
The 'sand' diagnosis may be right but what you describe could still be only batteries.
