SERVICING PRECAUTIONS
s Do not use a magnetized screw driver for screws
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.
s When replacing the anode cap assembly (CRT) or
anode lead assembly (F.B.T.), remove the anode
lead holder from old one and attach the holder
again to new anode lead.
s Check the point of anode lead in a straight
line, if it is winding, please revise it.
