I think it sounds like a grounding/connecting issue at the BNC receptacle.
Obvious questions: have you tried with other BNC cables? Multiple cables all exhibit the same behavior?
If you have an image prior to completing the twist-lock on the BNC, that makes me think it isn't the wiring so much as the BNC receptacle you're plugging into might be warped or damaged. Check the inside of the receptacle to make sure the receiver is not bent or otherwise damaged. Also, make sure the rounded BNC receptacle housing isn't bent or warped.

Tiffen has already been in contact with me, so that's great customer service.
I'll have to unscrew the top stage om Friday to see what's going on.

You'll likely find the world's most simple fix. The chassis-mounted BNC is likely slightly loose. When you push in and turn, the wires within may be crossing against each other and may be grounding out. You'll know it when you open the stage ( which is not complicated ).
Tighten down the nut, apply a dash of nail polish so the nut cannot turn out again, and you're set !!

I tried this Peter. No luck. Thanks anyway. I sent the rig in, and the HD-SDI cable has to be replaced.
So case solved I guess.
