New EOS R1 won't boot / turn on

[CanonCameraUser]

I just received my EOS R1 today and unfortunately it won't turn on!

Here is what happened:

- I inserted a dead battery and the camera did not turn on. The camera turned on later when I inserted a charged battery. I selected a language from the view finder in the initial setup screen. On the screen to select the date and time I opened the LCD display to continue setup from there. At this point the viewfinder and LCD went blank and would not come back up. I waited a few minutes, then removed the battery as the camera seemed stuck.

- now the displays will not turn on. No lights will turn on. I've tried removing the battery for a few minutes. I've tried removing any attached lens as well as any memory card. I tried attaching to a computer via USB to see if EOS Utility would recognize it, but it did not. Nothing seems to help.

- If I put the bottom of the camera right up to my ear and insert a battery into the camera, I can hear a momentary buzz, so something is powering on, but nothing functions from there.

Does anyone have ideas on how to force a factory reset with some combinations of holding down the buttons while putting the battery in? Or any other ideas to get this working?

I'm really sorry to hear that.  I'm returning mine Monday to exchange for a new one. Who knows how long that will take though. I'll update the thread when I get a new working unit.

I had a similar issue with an R3 when they came out in 2021. Following these steps brought the camera back to life.

Unfortunately, you cannot reset a camera that will not power on.

I am having the same problem.  Just opened the box half an hour ago.  Good grief.

UPDATE - I double-checked the switch to the memory card door, and the camera powered right up.  Apparently it is VERY sensitive about making sure everything is nice and tight.

Agree.  This was the first thing I suggested in my initial reply.  Door closed and firmly seated.  Latch closed.

I ended up getting a replacement pretty quickly, from B&H, and the second one is working great!
