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.

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. 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.
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.

neck right and left. (When fixing DY with wedges, insert wedges
completely so that the DY does not shake.)
