Bent Pin in 20D

Anyone had a repair done at Canon for bent pins? A niece borrowed mine and now it needs to be repaired... and I'm not adept enough to try to fix it myself. Just wondering what the damage will be.

Are a lot of pins bent? They're pretty easy to straighten using tweezers and some patience.

Whatever it is, it is irrelevant. Send it to Canon for repair. Then send the bill to the niece, or, if she's a child, her parents.

Happened to my XTi little over a month. They fixed it for free, and also repaired a scratched focus screen in it.

Can't beat that price! But the niece (parents) should still pay the shipping charges.

I accidentally bent a bin on my 300D a year or 2 ago. The first thing I learned is that neither Canon or any of their authorized repair centers will try to straighten the pin, they will just replace that module. They said that once bent, a straightened pin would be too weak to last anyway. As the camera was out of warranty, I was told a rough estimate would be about $200.

So, given that info and the desire not to stick $200 into an older camera, I decided to give it a go myself. I got a curved dental pick which worked great to get under the pin and stand it up some. Then, I removed the lead from a relatively large lead diameter mechanical drafting pencil I had laying around and was able to slip the hole in the nib (?) over the pin and straighten it up. But then, as was gently (really) making some final small adjustments to the pin, it broke off completely. And guess what, the camera has worked perfectly without that pin ever since. As it turns out, not all of the pin are used in every application and some pins (i.e. ground pins) share their purpose with several other pins. I'm not suggesting that breaking the pin off is the best possible solution. But, if you end up having to pay for it out of your own pocket, you may want to give it a try as a last resort before shell out $200.

I've never seen a schematic of a CF card, but it's a serial device and most of the 50 pins will be unused. How many contacts does an SD card have, anyway? 5 or 6?

cf is similar to ide, so it is a parallel device, not serial.

Here is a link to the SanDisk CompactFlash Memory Card OEM Product Manual (8.8MB): http://www.sandisk.com …uals/OEMCFlashP​Mv12.0.pdf

What I don't understand is how these pins get bent in the first place. Near as I can tell, there is no way to insert the CF card into the camera crooked. Because of the different sized grooves in the sides of the card that correspond to the ridges in the card slot, there should be no way the card can be inserted incorrectly.

That's what I used to think. But one way is to accidentally get the card rotated 90 degrees from the proper orientation. The card is 42.80 mm on the "correct" side and only 36.40 mm on the "wrong" side, so it actually fits quite easily the wrong way. Not that I, nor "anyone related to me", would ever try to insert a card that way.

What did she do?

I agree.
I've been asking everyone I see that says they have or had a bent pin and I'm yet to get a straight answer as to what they did. The cards do not go in backwards, crooked, or upsidedown. I think you can force them in backwards if you really want to, but you will know it isn't in right.

Oops. A variation of the ATA bus. Please ignore my earlier pronouncements.

They certainly do (we in a 350d anyway) and its not too difficult to force it in.
I have done it with a SanDisk ultra II. I am not sure if these are any narrower than any other type although the slots should be standard.

I bent a couple of pins but did straighten them out myself using a very fine long screwdriver. This was about 11 months ago.

I have just had this camera serviced (for another issue) and they did pick up the fact that the pins had been bent and then straightened. Must have pretty good eyes. Anyway, I picked the camera up on Friday (6 July in New Zealand) after being with Canon for 57 working days (long story, dont ask!!!). I got my replaced parts back and the CF pin assy was one of the items they replaced. The part itself is rediculously cheap (NZ$6.84 + 12.5% GST = NZ$7.70) but they estimate that the labour componant of the work is about an hour NZ$110.00 + GST.

Anyway, the following is a picture of the replaced unit, it looks OK to me and had worked 100% since the time I straightened the pins and upto the time I took the camera in for a service. Sorry about the quality, bit hard to take a photo of such a small item with a macro lens of some sort.
