Will not power up, even with fresh batteries

You may have a more serious problem that will require professional repair, but the problem that you describe may be due to corrosion on the battery contacts inside that camera that is preventing full battery power from flowing to the camera. Remove the batteries and wipe the inside camera contacts firmly with a dry cloth (heavy corrosion may require cleaning with a wire brush, steel wool, or sand paper). Remove any residue that may have fallen into the battery compartment during cleaning, then wipe both ends of the batteries and reinstall them in the camera. This cleaning solves the problem about 90% of the time, and I hope it works for you.

I did some research and from my personal experience from when i put non rechargable batteries in my charger and left them and the gook in the battery corroded the metal contacts.Looking down inside my Fuji's battery compartment one thing comes to mind....its a long way down to the bottom how am i gonna get something down there?Well first off lets get rid of any battery acid by neutralizing it.Well i have a can of battery corrosion cleaner which works great on my car battery (Bought at auto store) Well you probably want to use something cheaper than store bought stuff so - basically its baking soda and alittle peroxide (the stuff you bleached your hair with) on a dish of some kind make alittle pile about half a tea spoon will do,now add just a little peroxide-yeah the stuff will fizz alittle not to worry-make a paste (like tooth paste).Ok,you don't need much-swab some on a cotton tip swab-stick it down inside and work it all around the metal contact area-repeat with a clean swab till it looks good-now use clean swabs to remove any residue.If the problem is really bad i suggest you now purchase some steel wool-med corse will do (hardware store ask for it).Pull off a small amount-enough to wrap around the tip of cotton swab-if need be use some masking tape to hold the wool on tip-you want the most on the tip!now work the tip all around untill you see the metal is clean.Since acid corrodes the metal will look dull but clean.Now use a can of air to blow out all the little pieces of steel wool that shed from the swab.Do the same to contacts on battery lid but instead of useing a cotton swab to steel wool the contacts just go ahead and sand with a wad of wool (make sure you clean off any little pieces of steel wool on both the top and bottom of battery contacts).Hope this helps someone,Gary Malcontent
