t.g. hit it on the head.
the source is "shielded", and unless there is a break in that shield, ie; loose connector, push on jumpers, chews in the cable, or just faulty cable, (some cables have only a few copper shielding strands, copper being a BAD shielding material), the t.v. is most likely at fault. most t.v.'s are shielded to a point, but not totaly.
check for the above shielding faults before throwing bricks at your t.v.............
