10d b ult in Flash Problem

My 300D exhibited the problem indicated by subtle_spectre and wouldn't pop up. When I manually popped it up and took a picture inside with low light, the flash also did not fire.

I had recently been using and external flash in the hotshoe of the camera (with SafeSync, of course). When I checked the camera's hotshoe, I noticed the small microswitch on the right side of the hotshoe, under the side rail, was still pushed down. I got a small screwdriver and pushed the spring-loaded contact down a couple of times, the switch popped up and the flash started working.

Might be worth a shot, especially if you've been using the hotshoe for any kind of device such as a flash or remote trigger.

Edited to add: A picture is worth 1,000 words (or at least as many as in the above post). At least my old P/S camera has a decent macro mode.

Great post. I didn't know that. Thanks.

No big deal...I SO appreciate it when anyone tries to help. Thanks.

So, I am sure I have dust (mixed with now dried sweat) in this little micro-switch which has it jammed up. Can anyone think of a remedy to allow it to pop back up?

Perhaps, and I am in no way certain of this and I would be very hesitant, a drop of isopropyl alcohol or a drop of electrical contact cleaner would help...if the unit is shut down and batteries removed and allowed to dry, etc. Is that even remotely dangerous? ( I can hear the howls now!)

Otherwise I have to send to Canon under warranty...

I saw in another thread that the hot shoe is removable. My camera's at home, so can't swear to that, but you might search the fora to see. If it is, from MTalley's pic it looks like maybe removing the shoe would make the switch more accessible. If you can get to the danged thing, and if it is bodily grunge and dirt, then a tiny bit of isopropyl alcohol on a cloth would probably pose the least risk, he says confidently. Insert standard disclaimers here, blah blah blah. The alcohol would stand the best chance of cutting through the grunge, and if there wasn't enough of it to drip I'd at least be willing to try it, if it were my camera. The white plastic switch plunger in the picture will be pretty impervious, and the underlying switch will be safe if there's no drip. (I might even be tempted to try a dot of WD40 on a cloth, but you didn't actually read that here!!)

Cool news...thnaks. I found this link: https://photography-on-the.net …highlight=hotsh​oe+removal
Of course, I am at office and delicate, dainty instruments are at home...

TOUCHDOWN! The flash pops up! No shipping costs...no insurance...no being without camera...no dealing with Canon. Thank you all who helped.

Note: On my 20D, the micro-switch plunger is located under the left rail as you look at the camera from behind the viewfinder.
