version 1.12.2 ,
the modern TV disappears when you break it with your hand, (it breaks fast) and when you paste the link after leaving the TV interface, the link disappears

I too am having the same issue

The TV might have to be off first but links do work if you add them while in creative.

I'm having the same issue. Any interactions with the TV are not saved, unless you're in creative mode. Which is fine for admin stuff, but not helpful for others in a SMP environment :(

this happens to me too. Is there no fix to this? I can't find a config file for this mod.

The config for this mod is named "cfm.cfg", which really should be renamed to something more straightforward like CrayfishFurniture or something similar.

cfm = CrayfishFurnitureMod, it's short and sweet, imo
Also, the TV breaking and not breaking is fixed in 6.3.0

So, I might have found an additional bit of info for this issue. I'm running this mod on a 1.12.2 server and I've noticed that I cannot add to the TV unless in creative mode. If I try to add in survival I cannot edit any of the TV's settings but if I switch to creative everything works fine. Hopefully this helps.

Closing since I won't be maintaining 1.12.2 anymore.
