ABSTRACT:
A video display appliance comprising a cathode ray tube 2 having a deflection yoke 22 mounted thereto, a cabinet 4, and a back cover 6, the cabinet and the back cover being connected to house the CRT. The video display appliance also comprises a magnetic field absorbing coil 30 placed between a glass envelope 12 and the deflection yoke 22, a magnetic field remover 25, a back plate 34 mounted on a video board 27, a below plate 28, and a shielding member 60, 160 or 260 secured detachable to the inner surface of the back cover 6, for shielding the electromagnetic field emitted from the deflection yoke. The shielding means comprises an oblong closed-loop wire 62, 162, 262 or 265, and lead wires 64 having at each end a ground terminal. Accordingly, the electric field emitted in an upward direction from the deflection yoke is easily eliminated by means of the shielding member having a simple construction and being easily installed.
