Canon R3 not turning on

[waltzink]

So I've also had this problem with my R5 and now my R3. Turn on the camera and nothing. If I remove and reinsert the battery? It turns on. When I got the R3 I updated the firmware and initially that seemed to fix it but I was shooting an event last night and it started this again. Turn on. Pull battery. Reinsert battery. I have tested this with and without the EF-R adapter and with several lenses (RF 24-105, EF 70-200, Sigma 24-70) and every situation I have the same issue.

I've seen that this was an issue and wondered if anyone has figured out what causes this? Thanks!

If you have GPS enabled when the camera is “OFF”, then disable it.

GPS is disabled. Did a factory reset on it and will reinstall the firmware.

Installing firmware on a camera that is exhibiting electronic malfunctions such as locking up is highly inadvisable.  What if it decides to lock up in the middle of the installation?  I’d try a new memory card before I’d try a firmware update, which rarely fixes electronic malfunctions, anyway.  How could it?

Has the GPS always been disabled?  If you did a factory reset, then give it some time to see if the issue resurfaces.

GPS has never been turned on.
