20 Most Recent Canon EOS 400D / Rebel XTi Digital Camera - Page 5 Questions & Answers

Hi.

The repair requires disassembling. The Canon Rebel switch is mechanical and fails quite rarely. In your case the problem would be caused by a short in wiring below the switch. Before proceeding be sure that you are effectively turning off the camera from the switch, and not just letting the camera go to standby. Also be sure that you have enough camera or small electronic repair experience. The 400D is still a great EOS, better than some of the latest Canon EOS models.



To reach the switch you will need to remove a set of 4.4mm screws, starting from the two screws holding the left cover:



Remove the two 5.6mm screws holding the front cover.



Remove the front cover.

Remove the back cover pushing the retaining latch with your finger.

Use tweezers to undo the spring holding the back cover latch and remove the latch. This part is quite delicate. If you have not repaired watches or cameras before you risk to waste your EOS here.

Remove the two screws on the side of the camera grip and remove the two screws in front. Once the grip is loose, remove the camera grip.

Remove the screws holding the top plate and remove the top plate. This is another delicate step. The top plate is attached to several wires and ribbons. You must be very careful to avoid damaging the camera.

Disconnect the ribbon cables one by one very carefully. This is more or less what you will get (picture is a 20D):



Test and repair switch or wiring.

Perform the operations in reverse order to reassemble.

Instructions are similar to the ones illustrated in this manual explaining how to replace the shutter button on a Canon EOS 20D. The 20 D has some little difference, like On/OFF switch in different position, the four screws in front etc. The operations are however very similar to the ones for 400D described above. I have used pictures from 350D, 400D and 20D in my explanation. Hope this helps.

Check your settings - could be if very black night, and you set it to 100 iso film speed, and maybe you are on say 1/1000 of sec at maybe f16, then that's ok. You would maybe need an explosion in an oil refinery to capture much.

However, you perhaps could try this:

1 change the battery for fresh one, and see if it helps - sometimes, the shutter won't really shut if battery power is very low

2. change the mode setting to auto, and see if the flash pops up and takes a pix - then if the pix is good, the camera is still working

3. Reset the camera to the factory defaults, by:

• Firstly press the 'menu' button, then the up button above the 'OK' as many times as needed, until you see the top folders are highlighted.
  
  
• Press the right button near the 'OK' until you see the last folder highlighted. You will know this is highlighted when you see the first menu option that says 'Language'. The 3rd one down from that says 'Clear Settings'.
  
  
• Press the down button under the 'OK' until 'Clear Settings' is highlighted, then press the 'OK' button.
  
  
• Scroll up to your choice and press 'OK' to reset your Canon 400D back to default factory settings.

If that fails, back to Canon! - good luck

When you take off the lens and fire off a shot, does the mirror go up and return or does it stay up? If not, is it possible that it is staying up when the lens is connected? When you fire a shot, can you hear it returning?

If it really is just 16MB, then, that's about right for that camera.

You need to use about a 4GB -- that Gigabyte card to be able to hold many pictures.

16MB is just too small.

Hi, Those wouldn't have the serial number however it can be found with your camera's EXIF data which you can get from putting the photo on Flickr or into photoshop. If you need more help let me know.

This may not be the same as your issue, but our AF stopped working as well. I tried all the recommended fixes - removing the card and battery, recharging the latter, removing the lens and cleaning the contacts, etc. None of those things worked. However, I then switched to MF, requiring me to turn the barrel, and I realized it was stuck and just needed a little force to get unstuck. Might have been the humidity. Anyway, our problem was solved - AF was back to normal after that.

Welcome to Fixya
Err 99 could mean several different things, such as... Memory Card, Lens or Lens contacts....

Here's what you can try:
Remove the memory card an enable "shooting with out memory card" and see if you still get the error. If it works your memory card is bad. Try another lens if you can. Clean the lens contacts with a pencil eraser (be careful not to get eraser dust in the camera body or in the lens). Worst case scenario is, Err 99 could be related to the shutter failing which would mean a trip to Canon.

Life is too short to listen to bad headphones. Someone said: Sound really matters, because the music really matters. Now Beats by dr.dre here can give what you've been missing!

Error 98 & 99 means a NONSPECIFIC error message.

It may be a lens problem. It may be a shutter problem. It may be a battery problem. It's Canon's way of saying "Something happened, and we don't know exactly what, but we know it isn't right". You're going to have to try to narrow it down by using fresh batteries, trying different lenses, trying different shooting modes, shooting wide open in AV, manually focussing, turning off IS if you have it.

In short, if it happens regularly, try to identify what you're doing when it happens and how that differs from when it doesn't. But don't expect somebody else's solution to work for you. Their camera may have a different problem.

Are you try contacting the Canon Support?

Wow, four days ago.

I would think that the camera has dropped the shutter by now.

There is a mode in the camera that holds the mirror up out of the way for sensor cleaning but this is defaulted as soon as the power is shut off and then turned back on again.

Or the camera was set in manual mode "Bulb" and is waiting for the next command from the photographer to "drop" the shutter "takes a second press of the shutter button.

The lens may be loose (unlocked) and giving a bad command to the camera.

The Canon 40D has a shutter capable of 60,000 actuation so if you are close to this I'd say the shutter has been shot out of it.

Also sometimes the shutter release button sticks and gives the feeling or appearance of a stuck shutter.

Shutter switch also known as a release button have been an issue sometimes where dirt and oil from a person hands get down into the button.

To release shut the camera off, take the battery out, remove and reinstall the lens, shift the taking mode to "P" program or full automatic green box.

Try NOT connecting your camera to your computer.

The best way to download pictures from your camera to your computer involves removing the memory card from the camera and plugging it into a card reader (either built-in to the computer or connected via USB or FireWire). This is likely to be faster than connecting the camera to the computer, and won't run down your camera's batteries.

Once the card is plugged in, it will appear to your computer as a removable drive. You can use the operating system's drag&drop facility to copy pictures from the card to the computer's hard drive, the same way you copy any other files. Or you can use any photo cataloging program.

Download this program: FSResizer

Its a very friendly program that can RE-SIZED the images; just download and install it, then open the program, search the folder and pictures files in CD, select the pics that you want to "sized" and setting the new size ans destination folder in your PC and enter to finish.

Keep us updated about your advance; hope this helps.

What you can actually do is download the Zoombrowser which you can use to transfer the pictures in your camera on to a computer. The link to where to download the software is below. Once you're in the website, just choose your computer's operating system (XP, Vista Windows 7, Mac, etc.) then download the zoombrowser. There are other softwares for your camera on the said site which you might want to download as well.

When not in Auto mode you can up the ISO setting buy using the top semi circular button on the right side at the back of the camera. This adjusts the sensitivity of the camera so that not as much light is needed. The higher the ISO setting is the more sensitive the camera is. The trade off is that your pictures will have more"noise" in them. This is visible almost as a graininess if you enlarge the photo. The trick is to try and balance the amount of sensitivity,ie. the ISO with the acceptable amount of noise.

The error 99 message is often caused by the gold coloured contacts on the lens not making good connection with their opposite numbers on the camera body. Try cleaning them with a soft cloth, being very careful not to let any dust or fluff into the body itself. Maybe a tiny bit of alcohol would help but don't splash it about a lot!

I assume you mean one of the pins inside the camera body itself? This is quite a common problem and I believe it will have to be dealt with by a Canon Repair Centre. However it is not the end of the camera and is worth having done although I cannot say what the are charging at this time.

I'm afraid you can't view the image on the rear screen before you take the shot. On cameras like these,( semi and professional DSLR's) this is the norm. You view and compose the shot through the viewfinder and then you can check the result and view all your shots on the lcd screen afterwards

This model does not have a live view capability. To compose the shot you must use the viewfinder and then you can check the result on the lcd screen. This the norm on semi professional and professional DSLR's
