40D black stripes at high speed

Hi,
I recently got an used 40D with 16000 on the shutter count. Here is my problem. When I shoot at high speed I have a black stripe on my picture. The height of the stripe is proportional to the speed. The problem with stripe occurs from 1/8000 to approx 1/800. I cannot see the stripe at 1/640. If I use liveview, I have no more stripe.

What can I do apart from sending it back to Canon?

In picture it means:
At 1/4000

That's a sign of a bad shutter. The shutter needs to be replaced.

The shutter is open all the time when you use live view. That's why there's no issue using live view.

Yep.shutter needs to be replaced.
Will cost you ~$220-250 to get it fixed from Canon...if you just bought it from someone for top $, I would get a refund..
or you could try doing it yourself for ~$50..but that is NOT for the weak hearted..or for anyone who doesnt have experience with ths kind of thing...

good luck!

Thanks for the reply.

Is there something I can do to repair the shutter. It is not totally broken since it works up to 1/640 and under liveview. Maybe I don't know enough about that piece...

Is what I see the symptom of a problem that will only go worst?

I am wondering what is involve in replacing it myself (screw and un-srew, or soldering smd component and re-calibrating in a dust free environment)? I found some shutter on ebay for ~50$. They also claim to offer technical support.

What do you think, or does anyone have experience with third party repair such as: http://www.mcvr.com/ca​non_eos_d_series.htm

Best regards,

This doesn't look like failing shutter to me, it's more like flash sync problem.
Did you use any kind of strobes or flashes for the these shots?

Hi,
No flash or strobe was used. Those are picture of the sky on a cloudy day. The liveview at the same opening and time was able to capture it (without flash as well).

Hope it helps to pin point the problem,

Best regards,

I dont think it has anything to do with flash..but that would look very similar to a failing shutter..

fwiw, I wouldnt go with a '3rd party' repair place. in all reality you only save a couple $, and trust me, Canon takes care of you, and you can trust that it will be fixed properly AND also get fully cleaned and calibrated(a free check up) too...you cant go wrong with canon,imho.
If on the east coast I highly recommend the Newport News VA service location.

Now, the shutters on ebay are perfectly fine.I have used them on 20D,40D,and a 50D.
Try and find one from seller: procamerarepair
But, like i said, if you do not have ANY experience with electronics, AND the proper equipment to do this kind of work, do not try this yourself as you will only ruin the camera entirely, or cause more serious issues...trust me on that.
I have been modifying cameras for years, and know my way around just about every model from the 350D to the 1DmIV...and I still have slight hesitation when doing a shutter repair as you have to disassemble nearly the ENTIRE camera..that is a LOT of parts. and a LOT of work.
I would definitely pay the $ and just have Canon do it..and i do when I have the $..

even guys like me who do this work dont really bother with offering shutter replacement service as we would have to charger at least $150, and when Canon does it for only $50 more, I would go with canon any day of the week..(not that I dont have faith in myself..lol just keeping it honest..)

Well, in that case yes, it probably is the 'lazy' (leading) shutter curtain.
In Live View you don't see the dark bar because when you enter LV, half of the job is already done: shutter is opened and pressing the shutter button only closes it.

At least, that's how I understand it..

Hi,
200$ is a considerable amount of money, especially if the problem don't go worst. I currently can take picture at 1/8000, I just have to press the inner dial to activate the live view, then the shutter. Does this extra click worth 200$ (your opinion)?

Is this problem a symptom that need to be treated otherwise it will go worst (shutter brake apart, scratch the sensor, brake the mirror and create short cut in circuit as a result). This may worth the 200$.

I want your opinion,

Best regards,

Yes, failing shutter is not going to get better by itself, it's only gonna get worse.
If left unfixed, it could get bent or broken into pieces, and it can damage the sensor (AA filter, actually).
I've never heard of breaking the mirror of shorting the circuit, though..

You'll have to get it fixed sooner or later and $200-ish is not too much for that kind of work IMHO.

It will eventually fail (and make no mistake, your shutter IS failing) and it will potentially crumble as Hermeto mentioned. Once that happens, you're risking considerable expense.

Fix it now, it honestly will not last long, as many people here with the same problem have found.

Funny... Canon is the LAST repair choice I would use. Nobody and I mean NOBODY tops Toshio in NJ. And Canon here in Canada often sends many of their factory repairs to a third party company to deal with. I wouldn't be surprised if Canon in the USA does something similar.

I've gotten MUCH better service and results from third party repair centres. I don't even use Canon for WARRANTY work, I'd rather pay Toshio because I know it will be done 100% right. One reason why I didn't renew my CPS membership.

Anyhow, back to the OT, the strange thing here is the fact that your camera works in Live View mode. As far as I know, LV shooting also uses the shutter.

Hi,
Just speculating, is it possible that the mirror is slow-delayed? Faster the speed more of the shadow of the mirror we see. In liveview, the mirror is always up (is it?).

Does anyone knows an ultimate shutter failure test or slow mirror test?

Best regards,

Lloyd, having dealt with Canon-Canada ONCE, I would agree with you 100%. it was 100% crap service.complete idiots imho.
I was talking about Canon USA, and no, they do not outsource their repairs, afaik..even if they did, Canon still claims that the camera was repaired and Canon gives you a warranty on the work they provided...
Any of the third party shops I have seen on Ebay and other sites do not gaurantee anything...(again, afaik!)

OP. If $200 is a lot of money to fix a problem that needs to be addressed soon, then try another venue...I was merely saying that imho, the best bet(in the US, and FOR ME) is Canon Service repair centers..

I do not think the mirror would cause this. I have seen where the mirror(on a 40D actually) would cast a VERY small shadow on the very edge of the image, but nothing like what you are experiencing..

YES. I think the $200 is very much worth getting your camera back to 100% operation.
Unless you are happy using the camera in LiveView 100% of the time(which I would not be able to stand), get it fixed...
The fact that we think it is the shutter does not mean you will not have other issues.
But, the point is Canon checks EVERYTHING..not just fix the shutter like some other places will..and most of those places even say that they cannot gaurantee your issue will be resolved by having them work on it.....
why take that kind of chance?? send it to Canon and let them know you think the shutter is going bad, but to also checkout the rest of the camera..they will do it. and they will give you an estimate before they work on it, so if you do not like how much it will cost, have it sent back...no harm done.

imho. since you said you just bought this from someone...get your money back!!!!(unless it was via ebay where most people put 'no returns accepted')
There is obviously a serious issue with the camera..and leaving it alone is not going to help the situation..
so, either get it fixed. fix it yourself,etc..
or sell it 'for parts/repair'(well, I would hope people would be honest about something like this..) and try and get some of your $ back...

Good luck!!

Best regards,

odd but true, the mirror being in a shot would show up on the bottom, not the top (the image gets reversed top to bottom & left to right as it travels thru the lens) so no, I don't think the issue is specifically mirror related.

From checking my camera's liveview operation, mirror flips up when liveview initiated and shutter opens - when shutter button pressed, shutter closes, then opens for the shutterspeed duration, then closes again. Then shutter opens to continue liveview operation.
