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)

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.

SECTION 3

ADJUSTMENTS

Note:Hand degauss must be used on stand-by or power-off condition.

This model has an automatic earth magnetism correction function by using an earth magnetism sensor and a LCC coil. When using a hand degauss while monitor (LCC coil) is being operated, it sometimes gets magnetized, and the system may not work properly as a result.

•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 IK 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.

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. Put on landing sensor to CRT face.

11. Set LCC_SW to 12.

12. With landing checker, adjust DY position, purity, DY center and landing of the 4 corners.

(3) When adjusting at other than BH = 0, calculate the shifted value

from BH = 0.

13. Read VX and VY value which are the read out of magnetic sensor, and write to "LCC_VX_REF" and "LCC_VY_REF".

P4819(E) 3-1

14. Adjust landing by LCC_NS, LCC_LT, LCC_LB, LCC_RT, and LCC_RB. Adjustment of registers shall be limited within the following range. LCC_NS: 128 ± 15 LCC_LT, LCC_LB, LCC_RT, and LCC_RB: 128 ± 40

Set LCC_SW to 13, and Perform Service Save.

Note: Torque 22 ± 2 kgcm (2.2 ± 0.2Nm)

16. 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.

Plaster RTV to one side for other wedges.

17. Adjust top and bottom pins correction VR.

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

19. Check landing at each corner and in case not in specification, adjust landing of 4 corners with "LCC_NS", "LCC_LT", "LCC_LB", "LCC_RT", and "LCC_RB". The limitations of registers are shown below. LCC_NS: 128 ± 15 LCC_LT, LCC_LB, LCC_RT, and LCC_RB: 128 ± 40

20. Remove the sensor and wobbling coil.

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

22. Fix purity magnets with white paint.
