Safety Notice
SAFETY PRECAUTIONS
1:An isolation transformer should be connected in the power line between the receiver and
the AC line when a service is performed on the primary of the converter transformer of the
set.
2:Comply with all caution and safety-related notes provided on the cabinet back, inside the
cabinet, on the chassis or the picture tube.
3:When replacing a chassis in the cabinet, always be certain that all the protective devices
are installed properly,such as,control knobs, adjustment covers or shields, barriers,isolation resistor-capacitor networks etc.. Before returning any television to the customer,the
service technician must be sure that it is completely safe to operate without danger of
electrical shock.
X-RADIATION PRECAUTION
The primary source of X-RADIATION in television receiver is the picture tube. The picture
tube 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. Excessive high voltage may produce potentially hazardous X-RADIATION. To avoid
such hazards, the high voltage must be maintained within specified limit. Refer to this
service manual, high voltage adjustment for specific high voltage limit. If high voltage exceeds specfied limits, take necessary corrective action. Carefully follow the instructions for
+B1 volt power supply adjustment, and high voltage check to maintain the high voltage
within the specified limits.
PRODUCT SAFETY NOTICE
Product safety should be considered when a component replacement is made in any area
of a receiver. Components indicated by mark ! in the parts list and the schematic diagram
designate components in which safety can be of special significance. It is particularly
recommended that only parts designated on the parts list in this manual be used for component replacement designated by mark ! . No deviations fromresistance wattage or voltage ratings may be made for replacement items designated by mark ! .

Purity and Convergence Adjustment
COLOR PURITY ADJUSTMENT
(1) Before color purity adjustment,warm up the TV set over 15 minutes and fully degauss.
(2) Receive pure white signal in AV status and set the TV receiver dynamic.
(3) Go to factory mod MENU2. After write down the values of R-BIAS and B-BIAS, set the values of R-BIAS
and B-BIAS zero.
(4) Loosen the clamp screw of the deflection yoke and pull the deflection yoke towards color purity Magnetic
loop.
(5) Adjust color purity magnetic loop to make the green area at the center of CRT screen.
(6) Slowly push the deflection yoke toward the front of CRT and set it where a uniform green field is obtained.
Tighten the clamp screw of the deflection yoke.
(7) Restore the values of R-BIAS,G-BIAS AND B-BIAS.
CONVERGENCE ADJUSTMENT
(1) Receive a dotted pattern. Set the TV receiver dynamic.
(2) Loose the convergence magnet clamperrrrr and align red with blu dots at the center of the screen by
rotating(R,B) static convergence magnets.
(3) Align Red/Blue with green dots at the center of the screen by rotating(RB-G) static convergence magnet.
(4) Remove the DY wedges and slightly tilt the deflection yoke horizontally and vertically to obtain the good
overall convergnce. Fix them after the goob overall convergence got.
(5) Fix purity error is found,follow PURITY ADJUSTMENT instructions.

Operation Instructions
BATTERY INSTALLATION (REMOTE CONTROL UNIT)
1. Remove the battery cover.
2. Insert the 2 UM4-AAA 1.5V batteries making sure the polarity (+ or -) of the batteries matches the
polarity marks inside the unit.
3. Replace the battery cover.
Replace with new batteries when the TV set begins to show the following symptoms:
Operation is unsteady or erratic. Sometimes the TV set does not function with Remote Control
Unit.
Remark:
1) Alkaline Batterie Recommended
2) Remove batteries when they are exhausted or if the remote control is not to be used for a long time.
THE CAUSES OF INTERFERENCE
Incorporated in your TV receiver are the most upto-date devices to eliminate interference. Local
radiation however, can create disturbances which
visibly affect your picture. Proper installation, a
good aerial are your best safe-guards against
these disturbances.
RF INTERFERENCE
Moving ripples across the screen are caused by
nearby transmitting or receiving-short-wave radio
equipment.
DIATHERMY
Herringbone pattern and partial picture loss can
result from the operation of diathermy equipment
from a nearby doctor's surgery or hospital.
SNOW
Weak TV signals from long distant stations result
in an instead picture and give the effect of falling
snow. An antenna adjustment or antenna
amplifier may be needed.
GHOST
Multiple image caused by TV signals reflected
back from surrounding buildings, hills, aircraft, etc.
is minimized by correct aerial positioning.
CAR IGNITION
Nearby cars and electrical motors can cause small
streaks across the picture or make the picture roll.
