5D Mark IV Dead Body. NO power

[Faxan]

Hi everyone. I´m photographer from Spain.

Last thursday my 5D MK IV died. I was working and suddenly no batery. I Changed the batery for a loaded one but dont work. The camera is dead. No power, no red led when insert batery. I have read about this issue in some forums. There is many people with this problem. That´s worry. I dont know what is the problem, if is faulty cameras o lens thirds incompatibility that blown the PCB.. I bought the camera in January 2017. I can´t believe than canon allow this in a profesional camera.

Do you know about this problems with 5D MK IV? and if canon repairs this issues for free?

Thanks

"Don't you think we should be highlighting a problem ..."

Absolutely.  However, finding 6 or 10 or even 50 out of several thousands to tens of thousands made is not a verified problem. I hope it is not a trend but who knows it could be.

Has Canon refused to warranty the issue?

A superficially similar problem with the 70D turned out to be caused by a component failure on the motherboard, Many believe it's traceable to heavy use of the camera's video capability. Is there any evidence that heavy video usage could be at the root of the problems being reported regarding the 5D4?

You can add me to this list of photographers with this same issue. I only bought my camera a year ago.  I have had the camera die on my 3 times since June and I have heard of this happening to other photographers on forums I am a mamber to.  One had to pay over 400 for repair.  So far I have been able to fix the situation by taking the battery out and then putting it back in.  I have two shoots this weekend and am terrified my camera will die during the all day shoot 3 hours from home.  I am bringing my (VERY) old t3 Rebel as my back up.  

No one expects perfection - but like the story above about the Porche - I do expect Canon to fix it at their cost. This issue is happening too much to be a bad component - there is a manufacturing or design defect here that Canon needs to address.

Whether a camera has a reputation of failing or not, a second camera, backup, is mandatory if you are doing critical work.  Anything made by the hand of man can and will eventually fail. I never did any work for hire where I didn't have at least four camera bodies and half dozen extra batteries and CF cards.

Same thing happened to our camera. It is under two years and almost never used. Would be suprised if there are more than a a thousand pictures taken with it.

Would be interested to find out if this is a known defect.

I got my 5d mark iv in November 2019 and its less than two months and my camera battery died and didn't turned on again. What canon did to your camera? I just drooped it to retailer to send it to canon for inspection .

Hi Bob - to answer your question, I haven't used my 5D4 for video, so I think that rules out video use as the root cause.
Cheers, Robin

I think a few replies on here about this problem are not looking at what forums are for. They are to share information, good or bad, about the 5D MK IV. The only way to highlight a possible problem with a product is to share information about it. Canon are not going to admit to a problem when cameras are submitted on an individual basis. By finding out through a forum if the problem is widespread is a way of getting Canon to accept that it is an inherent problem on some Cameras - ever heard of the expression 'Friday built product' where only a certain batch or number of products turn out to be faulty through some kind of faulty component? I was in the electronics business for 35 years and can assure you it does happen!
