40D "can not Shoot".....help please

--

My 40D is about 5 months old and I had just down loaded some pictures. When I tried to take a shot after that I gots a busy message and the following message on the screen " Camera internal temperature is becoming too high, can not shoot". It refused to take any pictures. I have removed the batteries, the back up battery, chanaged the CF card but nothing works. Has anyone had a similiar experince and be able to help?.

The camera was bought from B & H in NY and I live in Sri Lanka.

Thanks

The Temp sensor must be broken, it thinks the camera is too hot when it is not. Time to send it to Canon.

A stupid temperature sensor should not be able to disable the camera. There should be a way to ignore the error and continue shooting, until the camera can be sent to Canon Service.

And if there was, people would probably override it, cause more damage to the camera before they sent it to Canon, and then say "well, it's not my fault, you allowed me to carry on using the camera"

My furnace has a temperature sensor on it that disabled my furnace when it malfunctioned. It's a safety feature and I'm glad it's on my furnace. Likewise, the temperature sensor is on the camera to prevent more extensive damage to the camera if temperatures exceed limits. Faulty components happen. It's a fact of life.

When the warning sensor is obviously in error, there should be a way to bypass it. If that happened to me during an important shoot, I would be furious. I shoot in hot weather very often, and I know enough to cover the camera when it is not being used. Use some common sense instead of relying on stupid sensors to tell you that you can't do something. The job of the camera is to get the photo, not to tell the photographer how to do the job.

The likelihood of a Canon camera overheating due only to a faulty component is very low, and preventing a shutter release would not prevent the camera from overheating in those cases.

A furnace left unattended is a different problem, and a temperature sensor should shut off the furnace if it appears that it is too hot. But after a person has checked for proper operation and confirmed that there is no problem, the temperature sensor should not prevent the unit from restarting.

The temprature sensor is where the problem is at. But What did I do to increase it? The camera had been in active for most of the day and I had only downloaded the previous days's pictures.

Looks like I will iether have to send it to back to the US for a service or to Singapore top attend to it. Back to the EOS 3 and slide filem for me. :-(

I wonder what happens if you remove the sensor. Will the software assume that the temperature is good, or will it demand that the expected sensor input be present? The sensor is obviously stupid, and there is no reasonable way to adjust it. At least your EOS 3 has no such stupid sensors, and a better focusing system too.

Your troubleshooting steps would have fixed the issue if it could be fixed easily by the user. The camera did overheat, overheats as soon as it's turned on, or part of that sensor circuit failed.

Oddly enough, I got the Busy yesterday after switching lenses. First sign was I couldn't change the aperture. Turned camera off and back on. Everything seemed normal until I took the next shot. Then I got the Busy lock up. Camera was stuck in a write loop. Been having problems with the 40D every since I bought a Ridata 8GB lightening series card. The first cheap card to ever give me grief. Anyway, I basically did what you did except for removing the PRAM battery. Lost the files on the CF card - camera couldn't create folder, but after a format the camera started working again. Canon says to send it in. My warranty expired last week. Glorious

At least yours went inside the warranty period. Not a real confidence inspiring situation regardless. Makes me wonder if the D in the xxD series is for Disposable. ;-)

If it were an important shoot, I would hope you'd have a backup camera. Cameras are electronic and they will fail. It's just a matter of timing on WHEN it will fail.

The temperature sensor is only one of thousands of components in the camera that could fail and prevent you from shooting.

Under normal circumstances, the temperature sensor is a good idea. It is a new feature that goes along with the live view mode because THAT can cause the camera to overheat under some circumstances.

Thus, it was deemed necessary to be able to have the camera shut itself down if long-term use of live view in a hot environment had caused things to overheat.

The chances of the temp sensor failing such that it erroneously prevents you from shooting are no greater than the chances of any of the other thousands of components that could also fail and disable the camera failing.

How many reports of this failure have you seen on here?

The sensor or an interconnect to it, or the input circuit that reads that sensor or even some internal logic that is used to evaluate that sensor reading could be at fault here.

Actually, the most likely scenario is that a connector or connection has failed. But who knows? Perhaps reflashing the firmware could fix it.

I'd try removing both batteries for a while and I'd also try re-flashing the firmware. But if none of that fixes it (and it most likely won't), then the camera has failed, and it will need to be repaired.

As others have pointed out, without this sensor, or with the ability to override it, people would probably toast a few cameras here and there, and then be really upset that Canon had not prevented it. You just can't win when you design something like this.

Yes, it's unfortunate that the camera failed. But it could just as easily have been a dead shutter, bad main-board (as happened to me) or any other part dying. Regardless, without a backup camera, you're done shooting.

The real issue for the OP is how he can best get warranty service on the camera given his location.

I'd recommend calling B&H and Canon USA service to see what they recommend.

If you've got the original sales receipt, you should be able to just send the camera with a copy of that receipt to any Canon USA service center, and have it fixed.

They may not be willing to pay for shipping outside the US, but still, it's better than paying for the repair, I would think.

Call Canon service and ask them what to do before doing anything, though.

They can tell you what they recommend.

Good luck with it. I've never heard of this happening before, but anything is possible. As a friend of mine is fond of saying: "It's just a machine."

If you were doing an important shoot for me and that happened, and it was an issue because you didn't have another camera with you, I would be the one that was furious, and you would find yourself out of a commission for being so unprofessional.

In other words, you're making up an event that shouldn't occur, to suit your own ends - the phrases "important shoot" and "only camera I have" don't go together. If you think otherwise, you are in for a rude awakening.

I had the same thing happen to me with my original 40D about 10 days after I purchased it. I don't know what the problem is because luckily for me it was still within the return/exchange period and I traded it for a new one.

Thanks folks.

I will send it back to the USA and try and get it changed :-(

The problem is that this disabling sensor is unnecessary, and it wastes money to install and connect to the firmware. It is only one more thing to go bad with an increasingly-complicated device.

There are obviously backup cameras, but that is not the problem. The problem is that I should not need to worry about being locked out of my camera by something that should not have been there in the first place. It would be enough to have a simple advisory message, stating that the temperature of the device had exceeded recommended norms, and displaying a choice to shut down or to ignore the warning and continue.

I am so tired of electronic devices going bad because of stupid programming and stupid "nanny features" that prevent normal operation and require costly repairs. There are things that photographers can anticipate, such as a broken shutter blade or a failed CF card. A stupid sensor claiming that the requested operation cannot continue because it is too hot, when in fact it is cold, should not be one of those things.

If I decide that I want to shoot in temperatures outside of the allowable limits that are stated in the printed manual, I expect the camera to continue operating and to let me worry about how to maintain it. If I had to quit shooting every time I used my camera in extreme temperatures, I would not have very many photographs.

Send it in and cross your fingers - you might get lucky and get a 'courtesy repair'. Sometimes Canon will repair an out of warranty camera without charge if it appears to be in good condition and not abused. I've heard of this happening enough times that I think it's not too uncommon.

Canon did it for my 1d MkIIN even though it was a almost a year out of warranty.

Good luck...

While I appreciate what you're saying, I think you have to look at it from the wider point of view. Canon are selling cameras to a huge number of people with widely differing technical knowledge and abilities.

To reduce the number of warranty claims from inexperienced customers damaging their cameras due to ignoring warning messages, they have put safeguards in that protect the camera against misuse and damage.

The downside of that is that people who know what they are doing have to put up with the limitations as well.

The camera is NOT saying it is too hot OUTSIDE. It is saying the camera's internal temperature is too hot. Something you would have no way of knowing otherwise.

Actually, it is very obvious when my camera is overheating due to my use of Live View. The hot sensation in my grip and the smell coming through the back of the camera tells me that I should switch the Live View off soon. Failure to allow the sensor to cool means hot pixels, which means more money spent removing them. I do not need some stupid sensor to tell me that my camera is hot and that I should lose the next few minutes of coverage because the temperature sensor did not want to overheat. That is the photographer's decision to continue shooting, and, fortunately, my camera has not shut down because of some stupid temperature sensor.

The biggest change in camera body temperature is caused by sunlight absorption, which is why I cover my camera during hot weather, when it is not being used. When it is being used in hot weather, there is a noticeable difference between the temperature of the white lens and the black camera body. There is another way to overheat the inside of the camera, but it would be even more obvious because the camera would fail before overheating occurred, and there would be visible indications of a serious hardware problem.

Can Canon install a disabling sensor that prevents idiots from using their pop-up flashes during stage performances, and another sensor to disable the "beep-beep-chunk-chunk-beep-beep-beeeeep" noises from the digicams when the room is quiet? That would be more useful to me and the audiences.

I actually have one Canon device that does have a disabling sensor, and that is my 580EX flash. It supposedly prevents overheating by shutting down after an extended strobe, but there is a way to bypass it; according to the manual, this may cause damage to the flash. I know enough not to try it unless it was necessary. Excessive heat coming from the flash head is very obvious, and it tells me that I should switch off the flash for a few minutes, and maybe consider changing the batteries while I am waiting for the flash head to cool down. It's only common sense, which a bunch of consumers apparently lack.
