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)

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.

NERGY STAR. If no signal is input to the monitor from your
computer, the monitor will automatically reduce power consumption as
shown below.

When your computer enters power saving mode, NO SIGNAL appears
on the screen. After a few seconds, the monito r ent ers power savi ng

3When one side of the rubber cap is

separated from the anode button, the
anode-cap can be removed by turning up
the rubber cap and pulling up it in the
direction of the arrow c.

•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.

•REMOVAL OF ANODE-CAP

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.

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;
LCC_SW = 0 (LCC Correction Current = 0)
FUNCTION_SW bit1 = (Auto Degauss = On)
CONTRAST = 255

3. Display green plain pattern.

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.

The red and blue must be within the
specification given right with respect to the
green.

A difference between red and blue must be
within the specification given right.

<Specifications>
Adjust so that the green is within the
specification given right.
4 corner adjust target : within ± 1

Note:(1) Do not attach more than 2 magnets on one corner.

(2) Attach magnets within the range of 80 - 100 mm from DY.
(3) Be sure to degauss and check when used magnets.

12. Tighten DY screw within specified torque, and auto-degauss.
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.

14. Adjust top and bottom pins correction VR.

15. Adjust the horizontal trapezoid distortion by DY horizontal trapezoid
correction VR.

16. Check landing at each corner and in case not in specification, adjust
landing of 4 corners with landing magnet.

17. Remove the sensor and wobbling coil.

18. Switch signals to R, G, and B, and then check that the pure colors have
good color purity.

19. Fix purity magnets with white paint.
