that CRT screens use a magnetic 'gate' to aim the electron beam. Magnetic fields from speaker drivers can interfere with the gate field and put that results in the beam getting sent to a point on the screen where it isn't intended to go, resulting in picture distortion.
LCDs and plasmas have each pixel controlled separately so there's nothing to aim and you don't get problems with unshielded speakers because of that. It's only a problem with CRT screens.
