EOS C500 Mark II- inconsistencies with SDI Out terminals

[bbellotte]

Hey all - 

Looking for any suggestions, I'm using a c500mkii with the Mon and SDI Out terminals (one on body monitor, 1 teradek sending signal to video village). I'm using a Shogun Inferno from the SDI Out (for a ProRes backup record) and the monitor out sends the video village signal. Recently, I've had inconsistencies with the SDI output and now it's stopped working altogether. I've tried to down-res the video to SDI Out (2K/1080, and 1080), but nothing. I can get monitor signal out to other devices no problem and the Shogun can receive the monitor out signal. I've tried a down converted signal (1080) to a SmallHD Cine7, but can't seem to get any SDI signal to that monitor regardless so that's probably a separate issue. 

I've updated the firmware (1.1.3.1) and no change. We used the C300 mkii before this and only had an issue until forcing an HD signal instead of UHD. We had a shoot with these cameras a couple weeks ago with this same setup and was able to get and record UHD to the shogun. Just wondering if anyone has any insight or experience with this? 

We generally shoot UHD (3840x2160), 23.98p, XF-AVC format.

Hi there! 

We're having a similar issue. Are there any techs that can provide some insight to this issue?

Hello,

Im having the same issue. However, my issue is with the c300mkiii. I typically run use monitor out send signal to an onboard smallhd monitor. Then use SDI out to send signal to my teradek. Two weeks ago the issue arose where i could no longer get a signal out from the SDI port. The monitor out port feeds signal to any device i try (i.e. teradek, onboard smallhd, 17” smallhd monitor). Ive tried changing up the settings for I/O but with no luck. Wondering if anyone has had luck trouble shooting? Or if you had to send in to canon for repair?

Thank you

We ended up sending the camera in for service. They replaced the I/O board. It was stupidly expensive. Around $1900. But it works now.

I had an issue with my 3G monitor port in my C300III back in 2021. The camera wasn't half a year old and Canon repaired it on warranty.
This article might be helpful for understanding the issue and the ever-present danger of using SDI:

Thanks for the reply and the link. I took it to Canon and it was diagnosed as a bad SDI port, which they replaced. Thankful it wasn’t the I/O board.

I'm glad it also went out well for you. I can't really tell what has been repaired in my case as they didn't let me know.

Hello everyone.   I'm having the same issue.   No signal out of the SDI port.   Mon out works fine and I can loop from the onboard monitor into the Teradek but it´s not supposed to be like that on a new camera.   Is there something I'm missing ?   Should I lower the resolution of the SDI port to 1080 ?   Is that possible and something I can do on the menu or most probably another repair on a six month old camera ?

I had both my Monitor port and SDI port go out but at different times. If you live in Southern California, I recommend you take it to the factory repair shop in Costa Mesa, CA. The first time I took it in when my SDI port failed, it was a $300 repair of the port itself. The second time my monitor out port failed. That ended up being the I/O board, which is a more expensive repair. Since id taken it in six months earlier they repaired it complimentary. So they're good folks over there and take care of their customers.
