Phil has summed it up rather well, above, and I'd just like to add that the process
of a shutter replacement in a Canon camera requires decent knowledge of electronic
assemblies and micro-mechanical mechanisims.

This is not to say that it can't be done by a non-Canon technician, but to stress
that the process requires something of a working knowledge of electronic
and small mechanical assemblies. If you understand how an electronic ribbon
cable attaches to another component, and understand how a bunch of seemingly
unassociated screws hold together the case of any given electronic device, and have
a basic understanding of how these electronic devices interconnect together while
knowing about the differences between the various interconnection methods,
then you're all set and ready for undertaking a repair on your own.

You may also need to know some soldering techniques, as Canon assemblies are heavy
on ground-wire connections, from my own experiences. I replaced an A690's broken display
recently, only to discover that the assembly is grounded six ways to Sunday, while the actual
assembly is grounded 'till the cows come home. Grounding was accomplished with the metal
frame of the camera, and has served well through a 10-day visit to the Arctic Circle.

I experienced similar symptoms to my 40D. Only works in live view, some pictures are haft over exposed, flash does not work and error 99. Sent it into canon beginning December, got in a week ago. It was a failed shutter. My 40D has 10k clicks, very disappointing but this hobby is not cheap.

LIVE VIEW F*CKING WORKS !

OK, if you can take photos in Live View, then you do not have a shutter issue. More than likely, you have a mirror lock up issue. This is something you can work around for the time being. I would find a local Canon place and show them what it going on. I can only imagine the mirror lock up would be less expensive because they don't have to get as far into the camera.

One thing about Live View, you can't AF in Live View. I believe you can use the AF-ON button to get focus between shots, but you will not be able to shoot moving objects in Live View. I use Live View from time to time and I focus my shot, then activate Live View. I never bother with it for sports or wildlife, only subject's that are not moving.

Even on my 50D there is no way to AF in Live View. If there is, I haven't figured it out.

Depending on what you shoot, you could be fine for the time being. I would still take the camera back to the Canon place and say 'look, the works just fine in Live View, so it's not the shutter.' See if you can get someone a little smarter to help you this time. I actually quite surprised they didn't try this at the shop. Live View and/or Manual Cleaning are two very good ways to see if the shutter is functioning. It sounds to me like the Canon rep you spoke with didn't think to check either of these, so I would talk to someone else next time.

50D can AF in live view, it has "live" focusing in addition to "quick" focusing which is what the 40D has. But if that 40D is having mirror trouble then the 'quick' focusing likely won't work. Live focusing is slow but it works, just press the AF-ON button in live view and make sure that the live focusing mode is enabled rather than quick mode.

Sounds like mirror motor issues if live view works perfectly. If the shutter was broken it would likely cover part of the sensor even in live view mode but you can check it yourself quite easily: just put it on a manual cleaning cycle or bulb exposure, take off the lens and have a look at the sensor to see if the shutter is hanging around. Try mirror lockup to look at the shutter itself on the first press of the shutter.

this happened to me also, i kept getting an err99 in viewfinder, but live view worked.
try calling canon, they have a bunch of steps you can try before sending it in. updating firmware, and some other stuff. unfortunately, i had to send mine in and they 'claimed' it was due to the shutter mechanism and cost me about $220 usd

Thank you for sharing! Now I can AF in Live View. LOL

Did you take out the 3 volt watch battery yet ? maybe take it out for a few min to clear all the circuit stuff. Could be just a small hardware/software hiccup.

Merry Christmas guys!

FireDragon, just where is the 3 volt battery?
I don't have a user manual on me on the trip to reference too at the moment.

Okay so now its basically impossible for me to get to Canon,
Heading home from holidays tomorrow and they are shut for the Christmas period
I live 10 hours from the Canon workshop! aha

I will probably send it in.
But thats where things start racking up,
$20 to send it in, then I get a quote, if I don't accept the quote from Canon, $50 for them looking at it and a $10 postage fee back home


The LV works fine and takes photos perfectly, but when I go to review the photo the 40D Error 99's
Manual cleaning is fine, I select it, shutter goes up, the screen says Clean and then I switch the camera off and shutter goes back down to normal.

Just testing the camera while typing this message,
Now the camera works fine in the viewfinder, will happily take the photo and does the full actuation!
I cannot view the photo because it just Error 99's after the shot ):


What is going on with this thing, its so eratic, help ! (:

It is starting to sound more like a circuitry issue. If you take the CF card out, can you view the images on your computer?

It won't do you any good at all if the camera is not writing the image to the card. If it is writing the image to the card, then there has to be some kind of internal circuitry issue. This is just my best guess. The problem with ERR 99 is the fact that is covers a wide range of potential issues. It is a very vague error. If you Google it you will see what I'm talking about.

I can view the images on the camera, just when I turn it on and go straight into it
Its when LV is enabled it Error 99's

The images are saved on the card and I can view them, they are all just as I had taken them.

Open up your main battery compartment. It will be right were the hinge is. CR2016 3V will be written on it. You will also see a finger grip on th side to pull it straight up.

Good luck........... Dennis

Err99 when you go to view the picture? Hmm, are you sure the pictures are being stored? Doesn't sound good. Check the memory card slot for bent pins.

Thanks for the tip FireDragon, the battery trick didn't work
Asked me to reset the date but didnt fix the issue

hpulley
I enable LV, take a photo, the photo shows on the screen for two seconds in review, then back into LV
When I press the review button manually, the camera displays the latest image for a split second and Error 99's.

Whereas if I don't enable LV and just go straight to review, the images load fine and I can review them all. Including the ones that I had just taken on LV.

Well, the good news is that it doesn't sound like a shutter problem.
Can you post one of the images?
Doesn't matter what it is or how good or bad it is.

Well, it's only good news unless it's a circuitry issue. If that is the case, it could be costly to fix.
