SERVICING OF HIGH VOLTAGE SYSTEM AND
PICTURE TUBE
When servicing the high voltage system, remove static charge from it by
connecting a 10k ohm Resistor in series with an insulated wire (such as a
test probe) between picture tube dag and 2nd anode lead. (AC line cord
ahould be disconnected from AC outlet.)
1. Picture tube In this receiver employs integral implosion protection.
2. Replace with tube of the same type number for continued safety.
3. Do not lift picture tube by the neck.
4. Handle the picture tube only when wearing shatterproof goggies and after discharging
the high voltage completely.
BEFORE RETURNING THE RECEIVER
Before returning the receiver to the user, perform the following safety
checks.
1. Inspect all lead dress to make certain thatthe leads are not pinched or that hardware is not
lodged between the chassis and other metal parts in the receiver.
2. Inspect all protective device such as non-metallic control knobs, tnsulatinq fishpapers,
cabinet backs, adjustment and compartment covers or shields, isolation resistor-
capacity networks, mechanical Insulators etc.
X-RAY
This receiver is designed so that any X-Ray radiation is kept to an absolute
minimum. Since certain malfunctions or servicing many produce potentially
hazardous radiation with prolonged exposure at close range, the following
precautions should be observed:
1. When repairing the circuit, be sure not to increase the high voltage to more than 34.0 kV
(at beam OIlA) for the set.
2. To keep the set in a normal operation, be sure to make it function on 29.0 ±1.5kV (at
beam 1.6
mAl in the case of the set. The set has been factory-Adjusted to the above
mentioned high voltage.
...If there is a possibility that the high voltage fluctuates as a result of repairs, never
forget to check for such high voltage after the work.
3. Do not substitute a picture tube with unauthorized types and/or brands which may cause
excess X-Ray radiation.

ADJUSTMENT PRECAUTIONS
This model's settings are adjusted in two different ways: through the I'C bus control and in the conventional analog
manner. The adjustment via I'C bus control include present-only variable data.
1) Calling the service mode by the microprocessor
G)Make a short-circuit between TP1001 and TP1002, and the microprocessor is put in the service mode (adjust-
ment through the I'C bus control).
® Perss the CH-DOWN key on the remote controller to get ready to select the modes one by one.
@Perss the CH-UP key on the remote controller to get ready to select the modes in order opposite to the avove
step
®.
@Using the VOL UR keys on the remote controller, the data can be converted.
@Removetheshort-circuitbetweenTP1001 and TP1002, and the microprocessor is put out of the service
mode.
2) Setting the initial (preset) values
G)Call up the service mode and turn on the main power switch. Anew E'PROM Uudgedby the first 4bytes) can
be automatically set to the initial data.
®The initial data 'ire as shown on pages 8,9,10 and 11.
@Note that some items of the data must be modified and the others must stay as initial.
NOTE: Afterthe chassis has been assembled, be sure to call up the service mode first and then turn on the
main
power switch, as discussed in 2-G)above. If the main power switch is turned on without the
E'PROM initialized, an excess beam current may flow into the circuitry.

1. Disconnect the antenna from the tuner antenna terminal.
2. Apply DC voltage at pin (4) (IF ACC) of IC201 (IC101).
6.0 +0.1 V TP202 (TP102)
3. Using a digital voltmeter, measure the DC voltage at pin (20) (PLL FIL) of IC201 (IC101).
TP203 (TP103):About 0.007 V corresponds to
10kHz .
• Prepare a digital voltmeter capable of reading down to the third decimal place.
4. Remove the DC voltage from pin (4) of IC201 (IV101).
5. Reconnect the antenna and receive the E-12CH signal. (With the AFT off, set the receiving frequency to
224.25 MHz.)
6. Connect the DC digital voltmeter to pin (20) if IC201 (IC101). Adjust T203 ( T103) to get the voltage
measured in the above step @.
Allowable error: +0.015 V (20 kHz)
2. vco ADJUSTMENT: T203 (T103)
1. Get the tuner ready to receive the E-9CH signal,but
with no signal input. Adjust PLL data.
2. Connect the sweep generator's output cable to the
tuner antenna. (RF sweep)
3.
Adjust the sweep generator's output level to
80dBIlV.
4. Connect 1heresponce lead (use a low-impedance
probe with wave detector; see Fig.t.) to the tuner's
IF output terminal.
(This terminal must have the probe alone con-
nected.)
5. Set the RF AGC voltage to 0-6V with no contact
with waveform.
6. Adjust the tuner IF coil to obtain the waveform as
shown in Fig.2.
Note: Be sure to keep the tuner cover in position during
this adjustment.

1. Receive the E-12CH (PAL colour bar) signal. if this
signal is not available, any signal above the E-5CH
band is acceptable.
-Field strength:
55-80 dB~N
Make sure the frequency is almost the same as
that of the received channel (± 3011Hz).
2. Using the channel setting control, make a frequency
of 224.25 MHz
appear on the screen. (AFT 011)(11
any other channel than E-12CH is received, make
its frequency on the screen.)
3. Turn
T204 (T104) coil clockwise first to have 6V
reading and then
counterclockwise to get 0.2 V
reading.
Within this range, adjust this coil to reach the volt-
age below.
4. Adjust
T204 (T104) so that the DC voltage at the
AFT
OUTterminal - pin (1) of IC201 (IC101) be 3.3
±0.1 V. (See Fig. 3.)

2. Set the volume control to MAX.
3. Connect the VTVM probe to the
Sl connector. (Pin G): L-ch, pin ®:GND, pin @: R-ch)
4. Adjust the sub-sound data so that the VTVM should read the following voltage. For the left channel.
Adjustment error: B.9+0.1 Vrms
Notes:

Adjust the raster rotation to0 eastward.
6. TIghten the deflection coillock screwsTIghtening torque:

7. Checkthe corners onthe cathode raytube screen. Cor-
rectthe

magnetic sheet.
Note: Makethis adjustment after warming up the unit at
thebeamcurrentof 1400+50!lA for30 minutesor longer.
If any other adjustment is made during the warming-up,
warm up the unit for 2 more minutesand start the purity
adjustment.
Note: Call the service mode with TP1001 (TP1002) and
pressthe single-colorkey on the processremotecontrol-
ler,and the green-colorscreen comes up.
Note: Afteradjustingthe convergence, set the "a"and "b"
landingsto 20 urn in advance.
2" SURROUNDING PURITY ADJUSTMENT
1. Make sure the deflection yoke (YPB) is positioned well. Receive the crosshatch signal and move the
deflectionyoke to roughly adjustthe YH and YV.(Fix the deflectionyoke with the wedge within 30 seconds.)
2. Call up the green-only screen,and set the beam current to 1400!lA.
3. With BH at 0 and BV as specified by the Production CommunicationSheet, make sure the landings at the
cornersare of rankA. If not, apply a purity correction magnetand readjustthe landings.
The magneticfield adjustment is referredto in the ProductionCommunicationSheet.

-Ranqe: 20mV/div.(AC)
-sweep time: 20/lsec/div.
(Usea 10:1probe.)
4. Adjustthe R-Y data so that the offset between the
no-signal and the signal line be minimum.See
Fig.12.
5. Call the SECAM black level adjustmentB-Y mode.
6. Reconnect the oscilloscope to pin (10) (B-Y OUT,
TP802) of IC901. Takethe same conditions as in
step 3 above.
7. Adjustthe B-Y data so that the offset between the
no-signal and the signal line be minimum.See
Fig.12.
