The built in Flash on my Canon 50D will not pop up.

This seems to have occured after using my External Speedlite flash so my first thoughts were that the hot shoe thing was pressed down still making the camera think an external flash was in still. This could still be the problem but I did try carefully lifting the metal bits that are pushed down with no joy.

I also tried using some sticky tape and lifting the flash when pressing the button to release the flash but flash did not come up. The sticky tape didn't give a huge lifting force but I wouldn't want to force it with any more strength anyway.

No error messages appear when pressing the release flash button when external flash on or off.

The exernal flash unit still works as normal so it is not the end of the world but would be good to fix this issue just in case I ever need to use the onboard flash.

Any ideas?

Thanks

Paul

perhaps just removing the battery and then putting it back in will reset some silly sensor? Like the old saying "when all else fails, reboot"

I had the same problem with my 40D, and I could gently lift it with my fingers while pressing the button. Not a lot of force -- but definitely more than the sticky tape. I remember someone else having similar problems...

Mine isn't popping up either for some time now, but since I rarely use it, it hasn't been any priority to deal with.

Thanks for the replies. I will try the battery reset thing and also if that doesn't work giving it a little more force pulling it up:)

my 20D sometimes needs help, but it damned sure throws an error message to let me know.

I blocked the flash on the 50D once, and it too had an error message.

Thanks Cory.

My 40D had a similar problem once and I did fix it by pulling up the "prongs" on the hotshoe. That didn't work this time so perhaps not the same issue.

Still haven't resolved this issue but when I went to look at setting up the flash last night I noticed I get an error message telling me an external flash is attached to the Camera even though there isn't so I suspect it must be the bits on the hot shoe being in such a way they think the external flash is still on. I have tried prising them upwards with no joy.

I think you have found the cause. Now, as to the solution, good question. I ass-u-me that the switch attached to the one little button that gets depressed upon insertion of a flash is being made, when it should not be. Whether that is due to sticking of the button or failure of the switch is an open question. It would appear that disassembly may be required in order to diagnose and fix it.

Thanks Kirbic. I don't fancy taking it apart so it may be a trip to the Canon Repair centre. Hopefully a fairly inexpensive fix? Fortunately I have my 40D still so will not be without a camera. Then again I could just ignore it and always use the external flash though it does feel a bit over the top sometimes to have the external on just for a simple family piccie.

LOL, well since I've been shooting with the 5D for 8 years or so, I don't remember what an on-board flash is! More importantly, I really don't miss it. Even for casual pics, I will bounce an on-camera 580EX off a ceiling.

I found a few threads on this issue and it would appear there is a tiny button under one side of the hot shoe "rails" that is either stuck in or has broken off. It is very difficult to see even using a magnifying glass to determine whether the button is there or not. However one such thread included detailed instructions how to remove the hotshoe elements and even included details how to fix a missing button with a small piece of a paper clip. It looks fairly easy so may give this a go and let Canon pick up the pieces if it goes pear shaped.
11/19/2013 10:38:36 AM · #13
I believe I have seen those instructions before. Could well be worth a try.

Have you tried putting the external flash on and off the camera a few times? That may be enough to get it working again.
If you know where the item is now, you may also try using a tooth pick to put a tiny drop of WD40 in the critical spot on the hot shoe, or on the flash itself where the button makes contact, then put the flash on and off the camera a few times to see if that will turn it loose.

I've had similar issues with my cannon. Sometimes mine pops up and won't go back down. One time it was up for more than four hours and I had to call the doctor.

LOL.... Thanks for the soup on my keyboard.

Thanks MelonMusketeer

Yes unfortunately I did try all those methods and also some compressed air. I am not sure the actual button is there still - so damn small it is hard to see:)

Lol bhuge - that sounds very serious. I hope the problem is not keeping you up all night.

My 50D flash is broken as well. At first if I activated the flash, I could hear the motor trying to raise it so if I lightly pulled on it, it would come up. After awhile, I could no longer hear the motor so I think that's fried.

This is a link showing how to fix the pin under the hotshoe. I tried it but ended up giving up when the hotshoe plate wouldn't dislodge and I didn't want to totally trash the shoe.

Good luck

Thanjs Cuttooth. I suspect I will have the same problem you had and have to give up:)

Just curious- So there's actually a motor that drives it? Most of the ones I had seen were spring driven, so I'm just curious. I know Canon has the motor drive on the S p&s cameras, but didn't know it was also on their DSLRs.

The lift is spring driven, but I think a motor releases the hook that lets the spring lift it.

As suggested above, I used a lens to try to see the little button. No luck. Did see great gobs of gunk all over. Maybe they were gumming up the works. Being an electronics guy, whenever I solder on a printed circuit board, I get out the rubbing alcohol and a toothbrush to clean off the great gobs of gunk left over. Did that with the hot shoe. Dip the tooth brush in the alcohol and made sure I worked the bristles in under the sides of the hot shoe. Repeated a few times. Worked instantly! Popup flash now works great. And my hot shoe looks nice and clean too, even under a 10x lens.
