When I push the shutter button to take a picture it turns the camera off!
Internal system problem, needs service / repair

Changing the firmware won't change anything. The micro switch may be stuck in the on postition. If you are familiar with micro circuits, you could get the switch from Olympus or USCamera.com and replace it. Or, send the camera to Olympus or an Olympus authorized shop.

tiny bits of juice, remember? maybe (or I am sure) this tiny became corrosive inside the camera. (orange juice is the no.1 in my corrosive juice list, water is the least). You need to open and clean it, or a pro fix is necessary.

The "button" is actually just a plastic extension for the actual switch on the printed circuit board. You will have to dismantle the camera to gain access to the board and then use a DMM to test the switch contacts.

If your camera is still under warranty, the best thing you can dois to take it to the nearest official repair shop and Olympus Digital Cameras shouldfix it for free.
If your camera is out of warranty, or if Olympus refuses to repairit for free (happens sometimes if for example they suspect the camera has not been treated properly) you can try some ofthe methods listed here to repair it yourself. These simple methodshave helped a lot of people fix their cameras.
Before trying any of the suggestions, make sure your Olympus Digital Cameras has fresh batteries and it is in recording mode.
1) Remove the batteries from the camera, wait for a couple of minutes,then put them back in and turn the camera on.
2) Try compressed air. With a fine tip blow off gun and drycompressed air (20 lbs) set the tip between the lens turret and thecamera body and turn on the air while moving the tip around the lens.It should remove all dust and sand. Turn the camera on and it shouldfunction fine.
3) Another method is to tap the padded USB cover part on a hard surface, for example, a desk. It sounds so simple, but veryoften in works.
4) Try forcing the camera lens:
Turn off the camera. Place it on the back with the lens facing up and take a look at the spacing between the lens and the lens housing. If you notice that the gap is not even all the way around the lens, the problem should be easy to fix. This type of a problem usually occurs if the camera was dropped while the lens was extended.
Simply - VERY GENTLY - press down the lens on the side where the gap is the biggest. You should hear a "click" as it pops back into place. Try powering the camera back on.
If the lens doesn't extend at all or it extends, and then retracts again, do the following. Turn the camera off. Take the camera in one hand and with the other gently take one part of the lens and gently move it round in a circular movement. Do so with both sections of the lens. You will hear a "click" as it pops back in place. Power the camera on.
Another version of this fix would be to pull and twist on the largest ring of the lens while turning the camera on. Listen for a "click". If at first the focus seems to be off, turn the camera on and off and take lots of pictures, close ups and distance. Focus should slowly start improving.
5) If that doesn't work, there is an online guide for dismantling Olympus Digital Cameras and fixing the E18 error. (NOTE: Try this only if your camera is no longer under warranty!)It is a great guide with pictures and it can be found here.
There are 2 other guides, one Bulgarian and one Estonian with the take apart procedure for Canon cameras.They are not in english but have a lot of pictures which help with the process.

Fill flash and flash off modes remain selected after you take the picture. To cancel the selection, press the mode-selection button or close and reopen the lens cover/flash to return to the auto-flash mode. 
When bright light indoors or outdoors comes from behind the subject (backlighting), dark shadows (especially on faces) may occur. Use fill flash to lighten these shadows. 
When you do not want to use the flash, especially indoors where flash is prohibited, such as in theaters and museums, or when you want to take twilight scenes or distant subjects that are beyond the flash range, or capture the ambiance of existing light, use the flash-off feature. Use a tripod or place the camera on another firm support, and use high-speed film because the shutter speed in these situations will most likely be slow. 
Use this feature to include yourself in pictures. 
In this mode, the camera balances the flash and existing light exposure so you can take beautiful pictures of people at sunset or at night. Use a tripod or place the camera on another firm support, and use high-speed film because the shutter speed at night will most likely be slow. 
In this mode, you can capture the natural existing light of city-night scenes or fireworks at night. Use a tripod or place the camera on another firm support, and use high-speed film because the shutter speed at night will most likely be slow. 61 views
