CHAPTER 1 GENERAL ADJUSTMENTS
SAFETY INSTRUCTIONS
WARNING: BEFORE SERVICING THIS CHASSIS, READ THE “X-RAY RADIATION PRECAUTION”, “SAFETY PRECAU-
TION” AND “PRODUCT SAFETY NOTICE” INSTRUCTIONS BELOW.
X-RAY RADIATION PRECAUTION
1. Excessive high voltage can produce potentially hazard-
ous X-RAY RADIATION. To avoid such hazards, the high
voltage must not be above the specified limit.The nominal
value of the high voltage of this receiver is (A) kV at zero
beam current (minimum brightness) under a 120V AC
power source. The high voltage must not, under any cir-
cumstances, exceed (B) kV.
Refer to table-1 for high voltage (A), (B).
(See SETTING & ADJUSTING DATA on page 14)
Each time a receiver requires servicing, the high voltage
should be checked following the HIGH VOLTAGE CHECK
procedureinthismanual. Itis recommendedthat theread-
ing of the high voltage be recorded as a part of the service
record. It is important to use an accurate and reliable high
voltage meter.
2. Thisreceiver is equippedwith aFail Safe (FS) circuit which
prevents the receiver from producing an excessively high
voltage even if the B+ voltage increases abnormally.Each
timethereceiverisserviced, the FS circuitmustbechecked
to determine that the circuit is properly functioning, follow-
ing the FS CIRCUIT CHECK procedure in this manual.
3. The only source of X-RAY RADIATION in this TV receiver
is the picture tube.For continued X-RAY RADIATION pro-
tection, the replacement tube must be exactly the same
type tube as specified in the parts list.
4. Somepart in thisreceiver have special safety-related char-
acteristics for X-RAY RADIATION protection. For contin-
ued safety, parts replacement should be undertaken only
after referring to the PRODUCT SAFETY NOTICE below.
SAFETY PRECAUTION
Connect a 1500 ohm 10 watt resistor, paralleled by a 0.15
µF,ACtypecapacitor,betweenaknowngoodearthground
(water pipe, conduit, etc.) and the exposed metallic parts,
one at a time. Measure the AC voltage across the combi-
nation of 1500 ohm resistor and 0.15 µF capacitor. Re-
verse the AC plug at the AC outlet and repeat AC voltage
measurements for each exposed metallic part. Voltage
measuredmustnotexceed0.3voltsrms.Thiscorresponds
to 0.2 milliamp. AC. Any value exceeding this limit consti-
tutes a potential shock hazard and must be corrected im-
mediately.
WARNING :Service should not be attempted by anyone unfa-
miliar with the necessary precautions on this receiver.The fol-
lowing are the necessary precautions to be observed before
servicing this chassis.
1. AnisolationTransformershould be connected in the power
line between the receiver and the AC line before any serv-
ice is performed on the receiver.
2. Always discharge the picture tube anode to the CRT con-
ductive coating before handling the picture tube. The pic-
ture tube is highly evacuated and if broken, glass frag-
ments will be violently expelled. Use shatter proof gog-
glesandkeep picture tubeawayfrom the unprotectedbody
while handling.
3. When replacing a chassis in the cabinet, always be cer-
tain 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. Before returning the set to the customer, always perform
anACleakagecurrentcheckon the exposedmetallicparts
of the cabinet, such as antennas, terminals, screwheads,
metal overlays, control shafts etc. to 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:
AC VOLTMETER
0.15µF

PRODUCT SAFETY NOTICE
Many electrical and mechanical parts in this chassis have special safety-related characteristics.These characteristics are
often passed unnoticed by a visual inspection and the protection afforded by them cannot necessarily be obtained by using
replacement components rated for higher voltage, wattage, etc.Replacement parts which have these special safety charac-
teristics are identified in this manual and its supplements; electrical components having such features are identified by the
international hazard symbols 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 safety characteristics as specified in the parts list may create shock, fire, X-ray radiation
or other hazards.

TION” AND “PRODUCT SAFETY NOTICE” ON PAGE 3 OF THIS MANUAL.
SET-UP ADJUSTMENT
■The following adjustments should be made when a complete realignment is required or a new picture tube is installed.
Perform the adjustments in order as follows :
1. Color Purity
2. Convergence
3. White Balance
Note: 1.The PURITY/CONVERGENCE MAGNET assembly and rubber wedges need mechanical positioning.
Refer to figure 1.
2.Mounting position of the purity magnet assembly should fit to same position as old one because slightly difference
to the position depend on a kind of tube.
*There are no adjustment of purity and convergence in some picture tube (Unified with purity magnet)
COLOR PURITY ADJUSTMENT
NOTE : Before attempting any purity adjustments, the
receiver should be operated for at least fifteen
minutes.
1. Evenly degauss the entire screen.
2. Set the CONTRAST and BRIGHTNESS Controls to
the maximum.
3. Display built-in green raster using the TEST SIGNAL
SELECTION function.
4. Loosen the clamp screw holding the deflection yoke
(and remove the rubber Wedges).
5. Slide the yoke forward or backward to provide vertical
green belt (zone) in the picture screen.
6. Rotate and spread the tabs of the purity magnet (See
figure 4.) 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 mag-
net as shown below.
7. Move the yoke slowly forward or backward until a uni-
form greenscreenisobtained.Tighten the clampscrew
of the yoke temporarily.
8. Check the purity of the red and blue raster.
9. Put four wedges into the space between the picture
tube and the yoke to hold the yoke in the adjusted
position. (See figure 2.)
Donottilt the yokeby excessive insertionofthe wedge.
10. Remove cover paper of wedge and stick wedges on
the tube to fix the yoke in the adjusted position.

CAUTION: There 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 an-
ode of the picture tube.
2. Turn on the receiver. Set the BRIGHTNESS and CON-
TRAST controls to minimum (zero beam current).
3. High voltage must be measured below (B) kV.
Refer to table-1 for high voltage (B).
(See SETTING & ADJUSTING DATA on page 14)
4. VarytheBRIGHTNESS control toboth extremestobe sure
the high voltage does not exceed the limit under any con-
ditions.
FS CIRCUIT CHECK
The Fail Safe (FS) circuit check is indispensable for the final
check in servicing. Checking should be done following the
steps below.
1. Turn the receiver on and press the RESET button.
2. Temporarily short TP-(R) and TP-(X) 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 5 seconds to reset.
Then turn the power switch on to produce a normal pic-
ture.
Check that the set returns to normal operation when pin 12
of Z801(or emitter of Q472) is grounded with jumper wire.
Check the voltage across
