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 right.

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

This monitor meets the power-saving guidelines set by VESA, TCO’99, and ENERGY STAR. If no signal is input to the monitor from your computer, the monitor will automatically reduce power consumption as shown below.

Power mode	Power consumption*1		f (power)
			indicator
normal operation	≤	115 W (without USB operation)	green
active off*2	≤	3 W	orange
(deep sleep)*3
power off	0 W (approximately)		off

*1 Figures reflect power consumption when no USB compatible peripherals are connected to the monitor.

*2 When your computer enters power saving mode, NO SIGNAL appears on the screen. After a few seconds, the monitor enters power saving mode.

*3 “Deep sleep” is power saving mode defined by the Environmental Protection Agency.

• 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

a

1Turn up one side of the rubber cap in the direction indicated by the arrow a.

b

2Using a thumb pull up the rubber cap

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.

ADJUSTMENTS

• Landing Rough Adjustment

1.Enter the full white signal. (or the full black dots signal)

2.Set the contrast to “CONT”=MAX.

3.Make the screen monogreen.

Note: Off the outputs from R ch and B ch of SG.

4.Reverse the DY, and adjust coarsely the purity magnet so that a green raster positions in the center of screen.

5.Adjust the "H.CENTER" with the H CENTER Volume .(RV502 on the D board)

6.Moving the DY forward, adjust so that an entire screen becomes monogreen.

7.Adjust the tilt of DY, and fix lightly with a clamp.

Note: “TILT” shall be set at 0

• Landing Fine Adjustment

1.Put the set inside the Helmholtz coil.

2.Set the TLH to the Zero position.

3.Receive the single green signal.

4.Demagnetize the CRT surface with the hand degausser , and perform auto degaussing.

5.Attach the wobbling coil to the designated part of the CRT neck.

6.Attach the sensor of the landing adjustment unit on the CRT surface.

"a" and "b" must be equal.

10.Adjust the top and bottom pins with the TB.PIN VR complettely. And ajust the V.Size simulation.

11.Adjust the V.key (=H.Trapxoid) with the H-Trp VR so that [a] become equol to the [b]

12.If the corner is not within the standards, adjust disc magnet to satisfy L/ D adjustment standards.

Note:

(1)When necessary to paste magnets more than 2 pieces, be careful that the convergence and the distortion would be alterable.

(2)Paste within 80 to 120 mm from the DY on the diagonal line of the magnet.

13.If using the magnet, be sure to demagnetize with the degausser and check.

14.Remove the sensor and wobbling coil.

15.Fix the purity magnet paisted on the DY with the white pen.Fix it with the RTV.
