1Dx froze with black screen.

I was using the 1Dx today and suddenly it froze with a black screen. None of the button was functioning. i had to remove the battery and the camera reset. Does anyone have this problem?

There are several posts about happenings like this, and the workarounds.  Do a search on 1DX from the forum top page.

Did it show any error code ?

No error code. The LCD was all black. none of the buttons are working. the camera froze. have to remove the battery to reset. everything was back to normal after that . $7000 dollar camera doesn't give me that much confidence.

I had the same thing happen with my first copy of the 1DX. I heard something that sounded like the shutter locking up, and then the camera was dead. None of the buttons worked, couldn't bring up the menu, etc.

Turning off and back on solved it for me.

After wrestling with what to do, I eventually returned that copy (I was lucky, it happened within the first 30 days); the replacement hasn't shown the issue. Though, to be fair, it has far less actuations than the other one did when it locked up (happened around 2,200 photos).

I didn't get an error code on the screen, and I looked through the error log on the camera, and it didn't seem to know that this had happened. Could just be a hard crash.

What BIOS version are you using? Mine happened with the BIOS that originally shipped.

Wish you lots of luck :/

Others posted some nice debugging tips in there including using chkdisk (PC) to make sure there's no issue with the memory card.
