70D froze up and now won't turn on after removing battery

[jeffminder]

My cannon has worked perfectly for a year.  Today I set up for a shoot and the video locked up when it was refocusing on the subject.  Simply locked up, camera froze like a Windows computer 🙂

I turned the power switch to off, but it didn't turn it off

I removed the battery and that worked to shut off the camera

I put the battery back in and I have no power, tried 2 batteries and a USB power but the camera, well...she be dead.

...any ideas?

After speaking to Canon and getting my camera back with new circuit board, this is a known problem. Not a perment fix other than replacing board and eventually getting a new body (80D,90D, or whatever). We can be sure it too will have some error code to shut it down after a couple of years. This was true with my EOS 10D and EOS 50D. Thanks for the extended warranty. I'll definitely get rid of it before the warranty go out.

Did you ever get a resolve for your issue? 

[michellecorm]

Did you ever figure out a solution? 

[m0ses01]

Yes Michellecorm they replaced the mother board and cleaned the camera.

Is the motherboard and pcb the same thing? Mine is currently in the shop for "repair" for that.

Yes, It is the same thing. Recieved mine back from Canon and all seem t o work fine. Just don't have that secure feeling anymore, knowing it may stop at any time. I did start getting the Error codes prior, but they were intermittent. I could turn off the camera, take out the battery and it would work. Have two more years on my extended waranty and I will replace.

How long has it been since you fixed yours? It's going to cost me $250 for our local shop, pending they can "fix" it instead of replace it. I'm not sure that I made the right decision considering it's "only" $800 for a whole new body.... and I'm not even certain I trust Canon anymore. I just have so much invested in lenses.

Just got it back 2 weeks ago and did an event last weekend. Seem to be working ok. I'm in the same boat as you are. After doing some research on this, it's not just Canon.  It's a digital SLR problem. Very similar to  the cell phones. Their life is only about 2 to 3 years and it's usually cheaper to get a new one than repair the old one. I'll keep the body as a back up and probably get the 80D or somethig similar. Seems that using the live view and the video mode also shortens the life of the circuit. I do notice the camera get hot when doing long videos. My 70D is less than two years old, however I have over 10k clicks on the shutter. Always get the 4 year extended waranty.

i have the same problem. Based on search on the web, it seems pretty common.

Hello- I know this is an old thread but maybe I can still help someone.  I was shooting video this evening and the same thing happened as I have been reading; err message, lock down, and then complete shut down.  When I turned it back on, nothing.  I tried some of the ideas and videos posted here- nothing.  NOTE:  I was using a third party digipower battery.  I replaced it with a fully charged Canon battery and voila- back in business.  

I hope this helps someone.
