A signal is sent out to a physical object to give us a broadcast that we see and/or hear. If the object is damaged, the broadcast will come out differently and usually sub-optimally (i.e. like a human receiving a blow to the head and having subsequent neurological/psychological changes) or not at all (i.e. death). And yet, the physical TV/radio is not the source of the broadcast, but just a conduit for it to take visual/auditory form. I'm atheist but this does make me think that we don't know for sure that our physical being is the ultimate source of "us" so to speak.
