I have not looked at a plasma TV, Chip, but I would make that diagnosis

Hmmm - I wonder ... presumably the BPL couplers are capacitors coupling
appropriate RF from one leg of the power system to the next. Would they
also couple spuriously-generated RF at similar frequencies? (yeah, I'm
sure the couplers are more involved than simple RF bypass caps - that's
not the question here.)

The PPL rep accused you of mis-interpreting the RF from a neon sign as a
BPL signal. What DOES happen to the hash generated by a neon sign, then?
is it propagated through the power grid much further when BPL couplers
are present? How about other sources of broadband noise, like loose wires,
arcing insulators, etc? Will the entire BPL scheme spread all these other
spurious emissions far and wide?

And, by the way, since aircraft use AM, do they receive hash when they
fly over BPL lines? Are our brethren in aviation potentially useful
allies in this war?
