1930 SERVICE MANUAL
IMPORTANT SAFETY NOTICE
Proper service and repair is important to the safe, reliable operation of all NAPCEC Equipment. The
service procedures recommended by NAPCEC and described in this service manual are effective
methods of performing service operations. Some of these service operations require the use of tools
specially designed for the purpose. The special tools should be used when and as recommended.
It is important to note that this manual contains various CAUTIONS and NOTICES which should be
carefully read in order to minimize the risk of personal injury to service personnel. The possibility ex
ists that improper service methods may damage the equipment. It also is important to understand
that these CAUTIONS and NOTICES ARE NOT EXHAUSTIVE. NAPCEC could not possibly know,
evaluate and advise the service trade of all conceivable ways in which service might be done or of
the possible hazardous consequences of each w ay. Consequently, NAPCEC has not undertaken any
such broad evaluation. Accordingly, a servicer who uses a service procedure or tool which is not recom
mended by NAPCEC must first satisfy himself thoroughly that neither his safety nor the safe opera
tion of the equipment will be jeopardized by the service method selected.
WARNING
Critical components having special safety characteristics are
identified with an S by the Ref. No. in the parts list and enclosed
within a broken line* along with the safety symbol on the
schematics or exploded views.
Use of substitute replacement parts which do not have the same
specified safety characteristics may create shock, fire, or other
hazards.
Under no circumstances should the original design be modified
or altered without written permission from the N.A.P. Consumer
Electronics Corp. NAPCEC assumes no liability, express or
implied, arising out of any unauthorized modification of design.
Servicer assumes all liability.

1930 SERVICE MANUAL
SAFETY PRECAUTIONS
Picture Tube Replacement
The primary source of X-radiation in this monitor is the
picture tube. The picture tube utilized in this chassis is
specially constructed to limit X-radiation emissions. For
continued X-radiation protection, the replacement tube
must be the same type as the original, including suffix
letter, or N.A.P. Consumer Electronics corp. (NAPCEC)
approved type.
Safety goggles must be worn when the picture tube is
replaced.
Parts Replacement
Many electrical and mechanical parts in NAPCEC
monitors have special safety-related characteristics.
These characteristics are often not evident from visual
inspection nor can the protection afforded by them
necessarily be obtained by using replacement
components rated for higher voltage, wattage, etc. The
use of a substitute part which does not have the same
safety characteristics as the NAPCEC recommended
replacement parts shown in this service manual may
create shock, fire or other hazards.
GENERAL
A
ESD
All ICs and many other semi-conductors are susceptible
to electrostatic discharges (ESD). Careless handling
during repair can reduce life drastically. When repairing,
make sure that you are connected to the same potential
as the mass of the set via a wrist wrap with resistance.
Keep components and tools also at this potential.
To prevent ICs and transistors from being damaged,
highvoltage flash-overs should be avoided. For checking
the high voltage, a suitable meter should be used. The
picture tube should be discharged only as indicated.
Removing the chassis
- Remove the backcover
- Slide out the chassis
- After repair the connecting cables of the chassis
should be fixed in the original way.
Be careful when measuring the EHT-section and the
picture tube.
Use plastic instead of metal tools for adjusting. This is
necessary to avoid a short-circuit or to avoid causing a
circuit to become unstable.
Never replace components when the set is switched on.

SERVICE ADJUSTMENTS (Continued)
Note: The following adjustments need only be performed
if the CRT has been replaced. Minor corrections for
purity and convergence may be accomplished through,
the use of the Purity and Convergence Assembly located
on the neck of the CRT.
Color Purity adjustment (Refer to Figure )
. Loosen the yoke clamp screw and slide the yoke
back away from the rubber wedges.
2. Remove the rubber wedges (G) and slide the yoke
forward until it rests firmly against the bell of the
CRT.
3. Tighten the yoke clamp screw slightly so that the
yoke can still be moved with some friction.
4. Place the multi-pole Purtiy and Convergence
Assembly in the position shown in Figure .
5. Tighten screw (A) and turn securing ring (B)
counterclockwise. Position the unit so that it faces
in an East/West direction and degauss the
instrument.
6. Turn on the power and inject a cross-hatch pattern
signal. Allow a 0 minute warm-up period.
7. Roughly adjust the static convergence, using tabs
C and D.
8. Set the Vertical Centering Control (R524) to its
mechanical center. Disconnect R728 and R735 to
turn off the green and blue guns.
9. Adjust the Two-pole purity rings (E) to center the
red vertical and horizontal lines.
0. Inject a white pattern signal and move the
deflection yoke to obtain a full red raster.
. Turn on the green and blue guns by reconnecting
R728 and R735. If a uniformly white raster does
not appear, minor adjustments may be made by
adjusting the purity rings (E).
2. Inject a cross-hatch pattern signal to ensure that
the yoke is not tilted. If necessary rotate the yoke
to obtain a level raster.
3. Tighten screw F and adjust R524 for proper vertical
centering. Proceed to the Static Convergence
Adjustment.

magnetic rings (C) to converge red and blue lines at
the center of the screen.
4. Reconnect R728 to turn on the green gun and
disconnect R735 to turn off the blue gun.
5. Slowly spread, and if necessary, rotate the 6-pole
magnectic rings (D) to converge the red and green
lines at the center of the screen.
6. Reconnect R735 to turn on the blue gun.
7. For optimum performance, repeat steps through 6.
Proceed to the Dynamic Convergence Adjustment.

Figure 2 - Tilt yoke up or down to converge Red and
Blue vertical lines at 6 and 2 o'clock positions, and Red
and Blue horizontal lines at 3 and 9 o'clock positions.
. Inject a cross-hatch pattern signal and turn off the
green gun by disconnecting R728.
2. Tilt the yoke up and down to achieve the best
convergence of the red and blue vertical lines at the 6
and 2 o’clock and the red and blue horizontal lines at
the 3 and 9 o’clock positions (see Figure 2).
3. When the correct position has been found, place a
rubber wedge between the yoke and CRT. If the yoke
is tilted up, place wedge as shown in in Figure 3a; if
it is tilted down, place wedge as shown in Figure 4a.
4. Tilt the yoke to the left and right to find the point of
best possible convergence of the red and blue lines at
the edges, top, and bottom of the screen as shown in
Figure 5.
