SERVICING PRECAUTIONS
■ Check the point of anode lead in a straight
line, if it is winding, please revise it.
Anode lead holder
■ 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.
■ 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.

TO REMOVE CRT (Same procedure for R, G, B)
1. Remove CRT DRIVE Board, S. V. M. COIL and
DEF. YOKE from CRT.
2. Remove Lens Assembly.
3. Detach CRT Anode Cap from CRT.
4. Remove CRT Assembly from CRT Mounting.
CRT REPLACEMENT (Same procedure for R, G, B)
Reverse the removal procedures except the followings.
1. Anode Cable should be replaced with new one.
See "SERVICING PRECAUTIONS" shown below.
2. Install silicon (T461B) to the CRT, replace the Anode
cable and put enough silicon again on around the An-
ode Cap as illustrated.
CAUTION: Align the Anode cable as illustrated on page
