SERVICING PRECAUTIONS
@ Do not use a magnetized screw driver for screws
@ When replacing the anode cap assembly (CRT) or
anode fead assembly (F.B.T.), remove the anode
of Deflection Yoke and Velocity Modulation Coil to
avoid magnetization of electron gun.
Magnetization of electron gun will degrade basic
function and result in unbalance of right and left
shift of user static convergence, and result in no
variable quantity.
