I have a Rebel xt and am getting a Err 01 after I take a picture.

Hi! 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.
Thank you for choosing Fixya!

This can be either a mirror or shutter problem. Take off the lens and fire off a few shots while you look inside...you may be able to spot the problem. I don't think you will be able to fix it but a repair facility can.

You get to the viewfinder by putting an eye to it. The Rebel XT works as SLRs have worked for half a century, showing you the image through the viewfinder. Only more recent dSLRs have a Live View capability, allowing you to use them as point&shoot cameras by viewing the image on an LCD.

Hi,

It might be that it accidently change the display time of the picture or turned it off. There is a setting that you can change to display pictures. Check if that might be the problem.

Cheers

Rebel XT doesn’t have live view function. You cannot have picture on LCD when taking picture. If you can review the pictures and operate menu on LCD, your camera just fine.

change the lens or try cleaning the connector tabs with a eraser.

Try remove the lens, it may be faulty.

The Err 99 problem occurs due to dirty contacts between the body and the lens. I recommend cleaning the contacts. You can then turn Off the camera and then remove and reinstall the batteries to reset the camera to get the problem fixed.

usually its dirty ontacts on the lens

bad memory card most likely.
try reformatting card in camera.
try battery out for 10 seconds for full reset if that does not work.
may have a problem writing to card.
you can also try another card. cf i believe on that camera.
good luck.
