SAFETY INSTRUCTION
Before servicing and aligning this equipment, please read the following “X-RAY RADIATION
PRECAUTION” ,“SAFETY PRECAUTION” and “PRODUCT SAFETY NOTICE”.
X-RAY RADIATION PRECAUTION
1. Excessive high voltage can produce potentially hazardous X-RAY RADIATION. To avoid such hazards,
the high voltage must not be above the specified limit. The normal value of the high voltage of this receiver is
29 or 26.5kV(20”) at zero beam current (minimum brightness) under 120V AC power source. the high voltage
must not, under any circumstances, exceed 32kV.
2. Each time a receiver requires servicing, the high voltage should be checked following the HIGH
VOLTAGE CHECK procedure in this manual. It is recommended the reading of the high voltage be recorded as
a part of service record. It is important to use an accurate and reliable high voltage meter.
3. This receiver is equipped with a Fail Safe (FS) circuit which prevents the receiver from producing an
excessively high voltage even if the B+ voltage increases abnormally. Each time the receiver is serviced, the FS
circuit must be checked to determine that the circuit is properly functioning, following the FS CIRCUIT
CHECK procedure in this manual.
4. The primary source of X-RAY RADIATION in this TV receiver is the picture tube. For continuous X-RAY
RADIATION protection, the replacement tube must be exactly the same type tube as specified in the parts list.
5. Some parts in this receiver have special safety-related characteristics for X-RAY RADIATION protection.
For continuous safety, parts replacement should be undertaken only after referring to the PRODUCT SAFETY
NOTICE below.
SAFETY PRECAUTION
WA RN I N G:
Service should not be attempted by anyone unfamiliar with the necessary precaution on this receiver. The
following are the necessary precautions to be observed before servicing this chassis.
1) Since the power supply circuit of this receiver is directly connected to the AC power line, an isolation
transformer should be used during any dynamic service to avoid possible shock hazard.
2) Always discharge the picture tube anode to the CRT conductive coating before handling the picture tube.
The picture tube is highly evacuated and if broken, glass fragments will be violently expelled. Use shatter
proof goggles and keep picture tube away from the unprotected body while handling.
3) When replacing a chassis in the cabinet, always be certain that all the protective devices are put back in
place, such as: non-metallic control knobs, insulating covers, shields, isolation resistor-capacitor network
etc.
4) When replacing parts or circuit boards, disconnect the power cord.
5) When replacing a high wattage resistor (oxiode metal film resistor) on the circuit board, keep the resistor
10mm (1/2in) away from circuit board.
6) Connection wires must be kept away from components with high voltage or high temperature.
7) If any fuse in this TV receiver is blown, replace it with the FUSE specified in the chassis parts list.
8) Before returning the set to your customer, always perform an AC leakage current check on the exposed
1
metallic parts of the cabinet, such as antennas, terminals, screwheads, metal overlays, control shafts etc. to
A
be sure the set is safe to operate without danger of electrical shock. Plug the AC line cord directly into a
120V AC outlet (do not use a line isolation transformer during this check). Use an AC voltmeter having
5000 ohms per volt or more sensitivity in the following manner:
Connect a 1500 ohm 10 watt resistor, paralleled by a 0.15µF, AC type capacitor, between a known good
earth ground (water pipe, conduit, etc.) and the exposed metallic parts, one at a time. Measure the AC
voltage across the combination of 1500 ohm resistor and 0. 15µF capacitor. Reverse the AC plug at the AC
outlet and repeat AC voltage measurements for each exposed metallic part. Voltage measured must not
exceed 0.3 volts RMS. This corresponds to o.2 milliamp. AC. Any value exceeding this limit constitutes a
potential shock hazard and must be corrected immediately.

PRODUCT SAFETY NOTICE
Many electrical and mechanical parts in the chassis have special safety-related characteristics. These
characteristics are often passed unnoticed by a visual inspection and the X-RAY RADIATION protection
afforded by them cannot necessarily be obtained by using replacement components rated for higher wattage, etc.
Replacement parts which have these special safety characteristics are identified in this manual and its
supplement electrical components having such features are shaded on the schematic diagram and the parts list.
Before replacing any of these components, read the parts list in this manual carefully. The use of substitute
replacement parts which do not have the same characteristics as specified in the parts list may create shock, fire,
X-RAY RADIATION or other hazards.
B+ CHECK
1) Prepare the test equipment.
2) Use the DC voltameter at DC 200V position to test B+ test point, i.e. B+.
3) Connect the power plug to AC 120V/60Hz, turn on the power switch, wait for normal raster, Check B

INSTALLATION AND SERVICE ADJUSTMENTS
GENERAL
In the majority of cases, a color television receiver will need only slight touch – up adjustment upon installation.
Check the basic characteristics such as FS,EHV,and focus. Observe the picture for good black and white details
without objectionable color shading. If color shading is evident, demagnetize the receiver.
If color shading still persists, perform purity and convergence adjustments. This should be all that is necessary
to achieve optimum receiver perfomance.
FOCUS ADJUSTMENT
Adjust the FOCUS control (on T302) for well defined scanning lines on the picture screen.
HIGH VOLTAGE CHECK
CAUTION: These is no HIGH VOLTAGE ADJUSTMENT on this chassis. Checking should be done following
the steps below.
1. Connect an accurate high voltage meter to the second anode of the picture tube.
2. Turn on the receiver. Set the BRIGHTNESS and CONTRAST controls to minimum (zero beam current).
3. High voltage will be measured below 9 (20”)KV.
4. Vary the BRIGHINESS control to both extremes to be sure the high voltage does not exceed the limit under
any conditions.
FS CIRCUIT CHECK
The Fail Safe (FS) circuit check is indispensable for the final check in the servicing. Checking should be done
following the steps below.
1. Turn the power switch on and adjust customer controls for normal operation.
2. Temporarily short TP501 and TP502 on the Main Board with a jumper wire. Raster and sound will
disappear.
3. The receiver must remain in this state even after removing the jumper wire. This is the evidence that the FS
circuit is functioning properly.
4. To obtain a picture again, temporarily turn the receiver off and allow the FS circuit more than 30 seconds to
reset. Then turn the power switch on to produce a normal picture.

CONVERGENCE MAGNET ASSEMBLY POSITIONING
Convergence magnet assembly and rubber wedges need mechanical positioning. Refer to below figure 1.
COLOR PURITY ADJUSTMENT
NOTE: Before attempting any purity adjustment, the receiver should be operated for at least fifteen minutes.
1. Demagnetize the picture tube and cabinet using a degaussing coil.
2. Set the CONTRAST and BRIGHTNESS controls to the maximum.
3. Receive PM5515 monochromatic signal (such as G) to provide a green raster on the screen.
4. Loosen the clamp screw holding the yoke, and slide the yoke backward to provide vertical green belt
(zone) in the picture screen.
5. Remove the Rubber Wedges.
6. Rotate and spread the tabs of the purity magnet around the neck of the picture tube until the green belt
is in the center of the screen. At the same time, center the raster vertically by adjusting the magnet.
7. Move the yoke slowly forward or backward until a uniform green screen is obtained. Tighten the
clamp screw of the yoke temporarily.
8. Check the purity of the red and blue raster.
9. Obtain a white raster, referring to “CRT WHITE BALANCE ADJUSTMENT”.
10. Proceed with convergence adjustment.
11
FIG.3
CONVERGENCE ADJUSTMENT
NOTE: Before attempting any convergence adjustments, the receiver should be operated for at least fifteen
minutes.
CENTER CONVERGENCE ADJUSTMENT
1. Receive crosshatch pattern with a color bar signal generator.
2. Adjust the BRIGHTNESS and CONTRAST controls for well defined pattern.
3. Adjust two tabs of the 4-Pole Magnets to change the angle between them (see figure 4) and superimpose red
and blue vertical lines in the center area of the picture screen. (see figure 5)
4. Turn the both tabs at the same time keeping the constant angle to superimpose red and blue horizontal lines at
the center of the screen.(see figure 5)
5. Adjust two tabs of 6-Pole Magnets to superimpose red/blue line with green one. Adjusting the angle affects
the vertical lines and rotating both magnets affects the horizontal lines.
6. Repeat adjustments 3,4,5, keeping in mind red, green and blue movement, because 4-Pole Magnets and
6-Pole Magnets interact and make dot movement complex.
CIRCUMFERENCE CONVERGENCE ADJUSTMENT
1. Loosen the clamping screw of deflection yoke to allow the yoke to tilt.
2. Put a wedge as shown in figure 1 temporarily. (Do not remove cover paper on adhesive part of the wedge.)
3.Tilt front of the deflection yoke up or down to obtain better convergence in circumference. (See figure 5).
Push the mounted wedge into the space between the picture tube and the yoke to hold the yoke temporarily.
4. Put other wedge into bottom space and remove cover paper to stick.
5. Tilt front of the yoke right or left to obtain better convergence in circumference (see figure 5)
6. Keep the yoke position and put another wedge in either upper space. Remove cover paper and stick the wedge
on the picture tube to fix the yoke.
7. Detach the temporarily mounted wedge and put it in another upper space. Stick it on the picture tube to fix the
yoke.
8. After fixing three wedges, recheck overall convergence. Tighten the screw firmly to fix the yoke tightly in
place.
