SAFETY CHECK-OUT
After correcting the original service problem, perform the following safety
checks before releasing the set to the customer:
1. Check the area of your repair for unsoldered or poorly-soldered
connections. Check the entire board surface for solder splashes and
bridges.
2. Check the interboard wiring to ensure that no wires are “pinched” or
contact high-wattage resistors.
3. Check that all control knobs, shields, covers, ground straps, and
mounting hardware have been replaced. Be absolutely certain that you
have replaced all the insulators.
4. Look for unauthorized replacement parts, particularly transistors, that
were installed during a previous repair. Point them out to the customer
and recommend their replacement.
5. Look for parts which, though functioning, show obvious signs of
deterioration. Point them out to the customer and recommend their
replacement.
6. Check the line cords for cracks and abrasion. Recommend the
replacement of any such line cord to the customer.
7. Check the B+ and HV to see if they are specified values. Make sure your
instruments are accurate; be suspicious of your HV meter if sets always
have low HV.
8. Check the antenna terminals, metal trim, “metallized” knobs, screws, and
all other exposed metal parts for AC Leakage. Check leakage as
described below.
LEAKAGE TEST
The AC leakage from any exposed metal part to earth ground and from all
exposed metal parts to any exposed metal part having a return to chassis,
must not exceed 0.5 mA (500 microamperes).
Leakage current can be measured by any one of three methods.
1. A commercial leakage tester, such as the Simpson 229 or RCA WT540A. Follow the manufacturers’ instructions to use these instruments.
2. A battery-operated AC milliammeter. The Data Precision 245 digital
multimeter is suitable for this job.
3. Measuring the voltage drop across a resistor by means of a VOM or
battery-operated AC voltmeter. The “limit” indication is 0.75 V, so
analog meters must have an accurate low-voltage scale. The Simpson 250
and Sanwa SH-63Trd are examples of a passive VOMs that are suitable.
Nearly all battery operated digital multimeters that have a 2 V AC range
are suitable. (See Fig. A)

POWER SAVING FUNCTION
If you have VESA's DPMS compliance display card or software installed in
your PC, the monitor can automatically reduce its power consumption when
not in use. The monitor will automatically "wake up" if the keyboard, mouse
or other input devices are detected. The following table shows the power
consumption and signaling of this automatic power saving feature:

NOTE: Short circuit the anode of the picture tube and the anode cap to the metal chassis, CRT shield or carbon painted on the CRT, after
removing the anode.
•REMOVING PROCEDURES

1Turn up one side of the rubber cap in the
direction indicated by the arrow a.
2Using a thumb pull up the rubber cap
firmly in the direction indicated by the
arrow b.
•HOW TO HANDLE AN ANODE-CAP
1Don’t scratch the surface of anode-caps with sharp shaped
material!
2Don’t press the rubber hardly not to damage inside of anode-
caps!
A material fitting called as shatter-hook terminal is built in the
rubber.
3Don’t turn the foot of rubber over hardly!
The shatter-hook terminal will stick out or damage the rubber.

ADJUSTMENTS
• Landing Rough Adjustment
1. Display all white pattern (or black dot pattern).
2. Set contrast to 255.
3. Display green plain pattern.
4. Side back DY and roughly adjust green plain pattern to be centered on
the useful screen with Purity Magnet.
5. Adjust DY tilt.
Note:Set ROTATION to 128 and LCC_NS to 128 when adjusting DY tilt.
6. Lightly tighten the DY screw.
• Landing Fine Adjustment
Note: (1) After adjust W/B (9300k), measure the average of ΣIK with all
white video input, while CONTRAST is maximum and
BRIGHTNESS is center. And adjustment shall be made so that the
miss-landing become least after aging 2H with the IK 30% of
measured value shown above.
(2) The magnetic field shall be BH = 0.
(3) When adjusting at other than BH = 0, calculate the shifted value
from BH = 0.
1. Put the monitor in helmholz coil.
2. Set as follows;
4. Degauss the iron part of chassis with a hand degausser and degauss coil.
5. Degauss CRT face with a hand degausser again.
6. Input AC 230V to AC IN and turn the monitor off and on. Then autodegauss works.
7. Reset FUNCTION_SW bit1 to 0 (auto-degauss = off)
8. Degauss CRT face with a hand degausser again.
9. Attach wobbling coil to the specified place on CRT neck.
10. With landing checker, adjust DY position, purity, DY center and
landing of the 4 corners.
11. Check landing of the 4 corners, and adjust using magnet if they are not
in the specification.
<Specifications>

Note:Torque 22 ± 2 kgcm (2.2 ± 0.2Nm)
13. Adjust the vertical angle of DY to make top and bottom pins equal (a =
b). The horizontal angle shall not be changed (straight). Settle DY
upright without leaning, and insert wedges firmly so that DY shall not
move.
<How to place wedge>

good color purity.
19. Fix purity magnets with white paint.
Plaster RTV to one side for other wedges.
14. Adjust top and bottom pins correction VR.
15. Adjust the horizontal trapezoid distortion by DY horizontal trapezoid
