Well, believe it or not, some of the P&S cameras can be put back in working condition again, simply because some of the internal contacts or even the battery chamber contacts need to be thoroughly cleaned. One thing that I did was to go down to Lowes and pick up a spray can of contact cleaner, then use it to clean out the battery chamber, spray a little amount around the off/on switch and move the switch [or button] back and forth as well as any other sliding switches. I've actually revived several Olympus Stylus, Canon MLs, as well as other P&S cameras. One Canon ML sat in a box in my garage for about two years because it gave up the ghost, I thought. By spraying the battery chamber, the off/on rotating switch on the back, around the shutter button, moving the various buttons back and forth, placed in some new AA batteries, turned it on and immediately the AF images began appearing in the viewfinder. I still use that camera and it works like a charm. The same thing has happened with a couple of my Olympus cameras. It certainly worth a try plus the cost of spray contact cleaner is only around $3.00. You can also pick up spray contact cleaner at Radio Shack, but that's around $9.00.
