One of my TVs is rated to work anywhere, and another is not. All my computer monitors are rated for multiple voltages. For my TV that’s rated 120V only, I think it’s intentionally not certified for 240V because it’s an NTSC model. There might be a fuse set to blow if you plug it in to 240V, but if not, I would be only mildly surprised if it just worked.
Hm, from your explanation I’d expect TVs to work anywhere, but Jeff’s heuristic mentions them as not?
