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)

WARNING!!

NEVER TURN ON THE POWER IN A CONDITION IN WHICH THE DEGAUSS COIL HAS BEEN REMOVED.

SAFETY-RELATED COMPONENT WARNING!!

COMPONENTS IDENTIFIED BY SHADING AND MARK ¡ON THE

SCHEMATIC DIAGRAMS, EXPLODED VIEWS AND IN THE PARTS LIST ARE CRITICAL FOR SAFE OPERATION. REPLACE THESE COMPONENTS WITH SONY PARTS WHOSE PART NUMBERS APPEAR AS SHOWN IN THIS MANUAL OR IN SUPPLEMENTS PUBLISHED BY SONY. CIRCUIT ADJUSTMENTS THAT ARE CRITICAL FOR SAFE OPERATION ARE IDENTIFIED IN THIS MANUAL. FOLLOW THESE PROCEDURES WHENEVER CRITICAL COMPONENTS ARE REPLACED OR IMPROPER OPERATION IS SUSPECTED.

POWER SAVING FUNCTION

If your computer is equipped with power management, the monitor can support this function fully. Here the monitor does not distinguish between the individual energy-saving modes of the computer (standby mode, suspend mode and OFF mode), as it is capable of immediately switching into the mode with the highest energy-saving effect.

Stage	ON	Energy-saving mode
Power indicator	glows green	glows orange
Function	Monitor	Monitor
	operating	is dark
	normally
Power consumption	normal 135 W	reduced to < 3 W

If your PC detects inactivity (no input) it sends an appropriate signal to the monitor to reduce the power consumption (energy-saving mode). The power indicator of the monitor changes colour to indicate the status change.

Once an input is mode at the PC the screen contents are redrawn and full power is restored.

For detailed information on how energy-saving mode operates refer to the Operating Manual or Technical Manual of your PC.

When the monitor is switched to the energy-saving mode by the power management system a power consumption of up to 3 W is maintained to feed the circuit for redrawing the screen contents.

To completely switch off the power consumption, switch off the monitor or the system unit.

firmly in the direction indicated by the arrow b.

c

Anode Button

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 anodecaps!

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.

(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.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.

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

21T3 (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.

<Specifications>

Adjust so that the green is within the specification given right.

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.

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

<How to place wedge>

Green plain crosshatch pattern

		a				a and b should be equal.
c			d
						c and d should be equal.

b

Plaster RTV to both sides for the upper wedge. Make sure that they settle inside DY.

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.
