Canon 40d got wet

Put the camera in a bag of rice to dry it out, rice will absorb any remaining liquid, after 3-4 days remove it and see if it works, if no joy, then a new camera is in your future.

An My Canon EOS40D does not respond after taking 100 consecutive photos while taking a time lapse photo. I am using an Alpine Pulse intervalometer.

Have a look in the manual - some cameras have this as a 'fail-safe' in case people forget and leave them unattended. There may be a way to disable this 'function' in the menu system.Just looking at an answer to another similar query for this model, you may also need to disable 'automatic shutdown'.

EOS400D digital, I cant see the subject through the lens, I have taken the lens cover off

Hi Carol, There are two things that I can think of which will prevent you from sighting through the view finder. 1. When your camera is switched on for live-view shooting mode or vice versa. That is, you can only see the subject in the LCD screen or through the view finder one at a time. 2. If you are using the LCD screen to frame your subject and you encounter this problem, it is most likely caused by the settings of the camera. Try increasing the ISO to around 400 or above, reduce the shutter speed to anything below 1/20 and the aperture to around F:5.6 or less (that depends on your lens. Hope you resolve the problem by now but if you haven't try those tips. Regards.

Canon 40D unable to transfer files to my computer

ALTERNATE WAY TO TRANSFER PHOTOS AND VIDEOS TO A COMPUTER If your photos and videos are stored on the memory card, then remove the memory card from the camera and insert it into an USB memory card reader. Connect this USB memory card reader and memory card into the USB port of your working computer. Your computer will see this as an USB Mass Storage Device or an external storage device; you can then open the folder on the memory card and copy the photos and to your computer. Memory card reader is a handy device and is inexpensive. You can copy photos from other cameras and you can also download photos off your memory card to someone else's computer without the need of installing any programs.

The ISO expansion no longer displays H on the LED

In custom functions you have a place to enable or disable High ISO expansion. If it is set to disable then you will not see it as a choice.

  2. Turn the camera off/on switch to ON
  3. Wait 10 sec turn OFF
  4. Replace batteries.

Canon 40d camera will only shoot in manual mode

Using your fingernail, push in the lens contact pins in the bottom of the mirror box several times. Sometimes they get tarnished and make poor contact with the flexible circuit under them. Doing this scrapes off the tarnish. Screws come loose from the bottom circuit board and short it out. It contains the flash circuit so a short can throw 300 plus volts into a 6 volt circuit, damaging components. The lens contacts flex attaches to this circuit board. This is a common problem. Impact can cause flexible circuits to either come loose from their connectors or have one side pull out so some of the lands on the flex don't make contact. Did you drop the camera?

Internal Temperature too high to shoot.

This is obviously a problem with the internal parts of the camera. There are too many things it could be to give a definitive answer, and it would be too complicated for an amateur. If you take it into a local camera shop they should be able to run diagnostics on it and replace the problem.
Best of luck to you.
