SAFETY INSTRUCTIONS
GENERAL GUIDELI NES
1. It is advised to insert an isolation transformer
in the AC supply before servicing a hot
chassis.
2. Potentials as high as 33KV are present when
this receiver is in operation. Operation of the
receiver without the rear cover involves the
danger of a shock hazard from t he receiver
power supply. Servicing should not be
attempted by any one who is not
competent with the precautions necessary
when working on the high voltage
equipment. Always discharge the anode of
the tube.
3. When servicing observe the original lead
dress in the high voltage circuits. If a short
circuit is found, replace all the parts which
have been overheated or damaged by the
short circuit.
4. Always use the manufacturer’s replacement
safety components. The critical safety
components marked with
on the
schematics diagrams should not be
replaced by other substitutes. Other
substitute may create the electrical shock,
fire or other hazards. Take attention to
replace the spacers with the originals.
Furthermore where a short circuit has
occurred, replace those components that
indicate evidence of overheating.
5. After servicing, see that all the protective
devices such as insulation barriers, insulation
papers, shields and isolation R-C
combinations are correctly installed.
6. When the receiver is not being used for a
long time of period of time, unplug the
power cord from the AC outlet.
7. After servicing make the following leakage
current checks to prevent the customer
from being exposed to shock hazard.
LEAKAGE CURRENT COLD CHECK
1. Unplug the AC cord and connect a jumper
between the two prongs of the plug.
2. Turn the receiver’s power switch on.
3. Measure the resistance value with an
ohmmeter, between the jumpered AC plug
and each exposed metallic cabinet part on
the receiver, such as screw heads, aerials,
connectors, control shafts etc. When the
exposed metallic part a return path to the
chassis the reading should be between
4Mohm and the 20Mohm. When the
exposed metal does not have a return path
to the chassis, the reading must be infinite.
LEAKAGE CURRENT HOT CHECK
1. Plug the AC cord directly in to the AC
outlet. Do not use an isolation transformer
for this check.
2. Connect a 2Kohm 10W resistor in series with
an exposed metallic part on the receiver
and an earth, such as a water pipe.
3. Use an AC voltmeter with high impedance
to measure the potential across the resistor.
4. Check each exposed metallic part and
check the voltage at the each point.
5. Reverse th e AC plug at the outlet and
repeat each of the above measurements.
6. The potential at the any point should not
exceed 1.4 Vrms. In case a measurement is
outside the limits specified, there is the
possibility of a shock hazard, and the
receiver should be repaired and rechecked
before it is returned to the customer.

X-RAY RADIATION WARNING
The primary source of X-ray radiation in this receiver
is the picture tube. The chassis is specially
constructed to limit X-ray radiation. For continued
X-ray radiation protection, replace the tube with
the same type of the original one.
CAUTION
AFTER REMOVAL OF THE ANODE CAP, DISCHARGE
THE ANODE OF THE PICTURE TUBE AND THE ANODE
CAP TO THE METAL CHASSIS, CRT SHIELD, OR THE
CARBON PAINTED ON THE CRT WITH A HIGH
VOLTAGE PROBE AND MULTIMETER (SELECT VDC)
AND THEN SHORT CIRCUIT DIRECTLY TO DISCHARGE
COMPLETELY.

1. ELECTRICAL ADJUSTMENTS
1.1 Supply Voltage Adjustment
Connect a digital voltmeter to the cathode of diode D950 at the AV mode of the TV and set the
screen voltage to the minimum with the screen potentiometer. Adjust the main supply voltage (B+)
with P901 potentiometer to the following value (after supply adjustment, readjust Screen and focus
voltage).
14” : 105 VDC (for A33EKC01X01)
20” : 118 VDC (for A48EJW011X21)
21” : 110 VDC (for A51EFS83X191)
2. SERVICE ADJUSTMENTS
You need the special service remote control to enter and exit the service menu of the TV (you can
order it from the manufacturer). All buttons of the Service RC are same with the user remote control,
only service menu In / Out is added to it (please see the picture below).
Navigation
Service In/Out : Enters to / exits from the Service Menu
P+ / P- : Moves upward / downward inside the menu
V+ / V- : Changes the values or options
Red : for Feature Setup
Green : for Geometry Adjustments
Yellow : for White Balance Adjustments
Blue : for IF adjustment
2.1 IF Adjustments
2.1.1 PAL SECAM BG/DK/I
• Apply a 38.9 MHz PAL colour bar RF signal to the pin 1 of SAW01 with a pattern generator.
• Switch on the Service Menu with the Service RC and press “Blue” teletext button.
• Check that value of “PVC38” is “07”. Adjust the coil LC100 until the the “OK” is seen.
• Press “OK” button on the Service RC.
• Exit from the service menu with the Service RC.
Note: “PVF38” is for fine tuning. However, it is automatically applied when “OK” button is pressed
at “PVC38” item. Thus any manual adjustment is not required.
Page 15
2.1.2 SECAM L/L’
• “PVC33” and “PVF33” are reserved for Secam LL’. However, since there will be no Secam LL’
production, they would not be adjusted.
2.2 AGC Adjustment
• Apply a signal with amplitude 65±1 dBuV to the antenna input of TV with a pattern generator
(switch sound carrier to Off and switch “Video Ext” to On).
• Switch on the Service Menu with the Service RC and press “Red” teletext button.
• Find the “AGC” with P+ / P- buttons.
• Measure the amplitude of 38.9 MHz sinusoidal signal on pin 11 (IF2) of Tuner with an
oscilloscope.
• Change “AGC” to get 640 ± 20 mVpp.
• Add 5 to “AGC” value and change “2.AGC” to this value.
• Exit from the service menu with the Service RC.
2.3 Screen Adjustment
• Switch on the Service Menu with the Service RC and press “Yellow” teletext button.
• Find item “SCRN” in the menu.
• Adjust the Screen potentiometre until the the “OK” is seen.
• Exit from the service menu with the Service RC.
2.4 White Balance Adjustment
• Apply a white pattern with a pattern generator to the antenna input.
• Enter the Service Menu with the Service RC and and press “Yellow” teletext button.
• Select “G.DRV” option with P+ / P- buttons and change its value to “32” with V+ / V- button.
• Adjust “R.DRV” and “B.DRV” for white balance. If white balance can not be adjusted properly
change “GRN” value.
• Adjust “R.CUT” and “G. CUT” for red and green cut off (There is no blue cut off adjustment).
• Exit from Service menu.
2.5 Geometry Adjustments
• Apply the cross hatch pattern with a pattern generator to the antenna input.
• Enter Service Menu with Service RC and press “Green” teletext button.
• Adjust Vertical Amplitude with “V.4:3” option.
• Add 18 to ““V.4:3” value and change “V.16:9” to this value.
• Adjust vertical position with “V.POS”, vertical linearity with “LNRTY”, horizontal position with
“H.POS”.
• Substract 14 from “V.4:3” value and change “V1. 60” to this value.
• Add 4 to “V.4:3” value and change “V2. 60” to this value.
• Change “VP.60” to “V.POS” value.
• Change “LN.60” to “LNRTY” value.
• OSD window position can be centered on the screen with “OSD.H” and “OSD.V”.
• Exit from the Service Menu.
Note that: There is no horizontal width adjustment in this chassis. It can be adjusted by changing
power supply voltage in the interval of -1 and +1 V.
