I is safe for my tv to put a plasma ball on or near it?

I think it should be safe to put your plasma ball on top of or near
your TV set. No appreciable current should flow into or out of the
plasma ball (except on the power cord), because the glass is an
insulator and the base should be grounded (or at least disconnected
from anything). A small amount of charge is polarized in the glass, but
damaging currents cannot flow.
Nonetheless, you may observe interference in your TV reception,
particularly if you are watching an already weak broadcast signal.
Turning off the plasma ball or relocating it may help.
