How are they driving these CRT's?

Tim Weaver:
This Jimmy Kimmel set is pretty awesome. Sometimes the TV's are solid colors. That's easy enough, gut them and put a fixture in there. But SOMETIMES they are playing static?!?

So what gives? How are they driving these CRT's?

Geoff Doane:
My guess is that they have LCD screens in there, not CRTs, and they're fed from several computer video outputs.  The one downstage centre is already too thin to have a tube.  LCDs also have the advantage (over CTRs) of having a long enough persistence that frame rate isn't a problem for the video cameras that are shooting this.

Or maybe it's something else.  :D

My analysis?

The ones showing static are actual CRTs not connected to any signal.

The ones with the red "screens"? Just a thin cardboard box with some film (gel?) and a red light driven by a lighting kit.
