It could be the switch, the switch in the 300d is a software switch and doesn't actually cut and supply power to the camera. The best way to figure out if it is simply the switch is get the camera powered up and switch it off by opening the battery cover, If the camera powers up reliably opening and closing the battery cover your in with a good chance its just the switch.
other wise it could be anything, power supply, cpu problems... it may be worth re flashing the software as long as the camera can be coaxed into staying on once on, if the camera powers off while writing firmware it can be fatal to the camera...

Fitting isn't too much of a nightmare but involves removing both front and back of the camera and de-soldering quite a few wires.
There is also some danger involved as the flash capacitor is quite chunky on these and bite quite hard if you touch the wrong thing so its not recommended to open any digital camera if you don't know what your doing...

Parts for canon cameras are available from most approved service centers but its worth phoneing a few as the markup differs from one to another. another way is to buy a faulty camera from somewhere like ebay and use parts from that..

Best of luck

Finepix S8600 camera, when turning it on I get a warning screen 'turn camera off, remove obstruction or lens cap and turn on. Can't action, no obstruction

This may be because small particles of grit have entered the lens housing, preventing movement. It may be possible to dislodge them by holding the camera vertical with the lens pointing down and tapping the back of the camera firmly a couple of times. After that, while keeping the camera in this position, switch it ON and OFF a couple of times to try and loosen any foreign particles. You may have to repeat this procedure several more times before you achieve success.
Should this not work, then a trip to the repair facility is called for, I'm afraid.

Error message E45 comes up on camera - What can I do to fix it? Kodak easyshare V610. Message comes up when camera turned on. Batttery charged etc.

Is the lens extended? If so, try hitting the lens a couple of times with the palm of your hand and then turning off the camera. Turn it back on and let me know what happens. Sounds crazy I know, but those things are notorious for that error and that problem. You can also try taking out the SD card and see if the error goes away. Let me know what happens. Thanks.
