Fuji S7000 shuts itself down...without a reason

Are you sure you are using fully loaded battery's, because most camera's will automaticly shut down, when the battery voltage drops under a certain voltage. Sure your battery is still in tip top condition?
Don't use NiCD batteries, only alkaline and Ni-MH rechargable batteries should be used.
Page 15 of the manual shows how you can find out if you are using correct (with enough charge) batteries.

1)teh batteries are not the right typ use or alkaline or only NIMH
2) if shooting a cold area, keep the batteries warm by placing them in a inner pocket, until you ready to use them
3) battery terminal are diry, wipe them very well, with cloth and ethylic alcohol to 70%
4)the batteries have not been used for over a year.
God bless you

Well you mentioned that it worked fine yesterday with the battery out of the box. That should tell you that the camera and the battery are both fine. The issue is likely the charger itself. Try recharging it again, and double check that you inserted the batteries correctly, and that any switches (such as for 2 or 4 battery charge) are set in the correct position on the charger. If this doesn't work, take the charger back to the store for exchange/refund as defective.

There is no internal battery. When the batteries become discharged or removed, the camera retains the date/time settings for about 24 hours. Most people have backup batteries fully charged so when one set is low in the camera, they can make the change quickly.

What you do is have an ac mains adapter or a fully charged battery, a formatted card in your camera ( there should be a setting in your cameras menu for formatting) and the usb lead connected to your camera and pc. This should all be in your owners manual if you have one ( if not you can download one from a fuji website).
Check for a firmware update on a fuji website ( I had a look on a few and didn't find one) and down load it to your computer.
To check your current version hold the display back button down and turn the camera on. It should display the current version and ask if you want to up grade. If you don't ,or can't, turn off your camera.
Basically you down load the up date, then up load to your camera using the usb lead following any instructions along the way (get the manual for instructions. It will be easier). Mains lead is preferable as a battery could die halfway through and then you will be in trouble.
Hope this helps

May not work on yours but I have (hopefully had) same issue. I found that it will stay on if you keep pressing shutter to focus or switch straight to video and record - it stays on until you finish recording. I don't know why but after I moved the focus switch from caf to manual, took a couple of pictures and put it back to caf it now stays on.

That was only yesterday though so I cant say its permanently fixed yet.

Let me know if it helps.

Sounds like a bad LCD as I had a similar experience with a different brand. The part itself is probably not very cheap... but if you have $120 you could get the same camera, referbished.

Hi. If your camera is turning on with the lens stuck out. Turn the camera on, and without turning it off, open the battery door, and take the batteries out. Leave it for about 1-2 minutes and try again. This process is call power reset. Usually works. Good Luck.

a well known problem , this camera eats batteries there are high power (2950MaH) accus , those should be used with this camera even with 2700 MaH it is empty real quick

I think I Had that problem too. mine also quite suddenly started showing low battery even on new ones... it seemed better with non-rechargeable types. Now the reason I'm on this site is as the lens doesn't open.
