Built-in flash the built-in flash on my canon eos rebel 2000 will not pop up when needed

The range on your pop up flash is only about 15 feet, if your subject is further than that they will be underexposed. Try bumping up your ISO, also you can increase your flash exposure compensation by as much as two stops.

Hi, I have to Canon Rebel t1i and I had the same problem (built in flash not working). I tried a number of remedies I found on forums etc but none worked. I then tried this. In the external flash housing is a metal sprung plate which surrounds the five circular pins (one big, four small at the rear). If you get a small straight headed screwdriver and lift the front of this plate and at the same time pull it back towards you it will come out altogether.
I then removed the four small screws being careful not to drop them and took off the mount for the external flash and then tried the flash it opened straight away. I then cleaned all the area of the mount and the two plates and replaced them all ensuring I fitted them exactly as before. I then checked the camera again and presto working fine. I hope this helps everyone with the problem.

In addition to resetting all the camera settings you should also choose the "clear all custom functions" option that is also available from the same menu. Once that's done. Put the camera in Full Auto mode and see if the issue is resolved.

Sai.

Frustrating I am sure. I had the same problem on my first XTi. I cannot remember what the settings were, but I think I was set for portrait and had flash set as the white balance default source. Therefore the camera always popped up the flash assuming that I wanted or needed fill flash.

Change you white balance to sun/shade/tungston etc as is appropriate, choose a faster ISO speed in lower light levels and try using the P or Tv mode and use a shutter speed that generates a middle range aperature for your particular lens.

Be aware that the built in flash does not pop up automatically in all picture modes. Try it when in the different modes (on the mode dial) and see what I mean. Does it popo up when manually opened ?, (small button on front left hand side of the viewing pentaprism/flash housing.)

Flash will automatically pop out only in AUTO mode, if the camera needs some additional lightning. In manual modes, you should use the flash button located at the left down side of the flash compartment, to manually force the flash to pop up

Looking at camera from the front, the flash hinge is on the right hand side. Mine was corroded (due to sea spray). I removed the two arms which limit the travel of the flash, MAKE SURE YOU KNOW WHICH WAY UP THEY GO AND ON WHICH SIDE! remove the three very small screws which hold the cover on the flash and remove the cover. Now you can ease the bearing our and clean with Iso-propyl alcohol. Do not oil!. Reassemble and ensure it moves freely.

In my case, I borrowed a camera and when I got it back, err 05 appears. I've located a bit of old orange juice which sticked one of the sensors - you can see the sensors when flash is popped out.

Move the mode dial to the no flash setting (full clockwise position)which is basically full auto with no flash (page 47 of manual)

Does the 'pop up' pop up? If it does and still says obstructed- closes it and pop it again If it still persists Canon customer support will advise the next move. If a repair price seems high you could perhaps get a separate flash if the camera accepts them.
