TROUBLESHOOTING
If these symptoms occur when you begin operation, follow the suggestions below.
SYMPTOMS
No controllable keys although the POWER switch is turned
on.
No indication appears although the CONTROL key is
pressed.
Remote control is not possible. • Set the REMOTE CONTROL switch on the rear panel to
If the problem still cannot be solved, contact your authorized Sony dealer.
• Press the CONTROL key.
• Set the MANUAL CONTROL switch on the rear panel to

SAFETY CHECK-OUT
(US model only)
After correcting the original service problem, LEAKAGE TEST
perform the following safety checks before releasing
the set to the customer:
Check the area of your repair for unsoldered or
l.
poorly-soldered connections. Check the entire
board surface for solder splashes and bridges.
Check the interboard wiring to ensure that no
2.
wires art "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 cord for cracks and abrasion.
Recommend the replacement of any such line
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 microampers). Leakage
current can be measured by any one of three
methods.
I . A commercial leakage tester, such as the
Simpson 229 or RCA WT-540A. 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 lowvoltage scale. The Simpson 250 and Sanwa
SH-63Trd are examples of a passive VOM that
is suitable. Nearly all battery operated digital
multimeters that have a 2 V AC range are
suitable. (See Fig. A)
cord to the customer.
7. Check the condition of the monopole antenna
(if any).
Make sure the end is not broken off, and has
the plastic cap on it. Point out the danger of
impalement on a broken antenna to the
customer, and recommend the antenna's
replacement.
8. Check the B+ and HV to see they are at the
values specified. Make sure your instruments
are accurate; be suspicious of your HV meter
if sets always have low HV.
9. Check the antenna terminals, metal trim,
"metallized" knobs, screws, and all other
exposed metal parts for AC leakage. Check
HOW TO FIND A GOOD EARTH GROUND
A cold-water pipe is guaranteed earth ground; the
cover-plate retaining screw on most AC outlet boxes is
also at earth ground. If the retaining screw is to be
used as your earth-ground, verify that it is at ground
by measuring the resistance between it and a coldwater pipe with an ohmmeter. The reading should be
zero ohms. If a cold-water pipe is not accessible,
connect a 60-100 watts trouble light (not a neon
lamp) between the hot side of the receptacle and the
retaining screw. Try both slots, if necessary, to locate
the hot side of the line, the lamp should light at
normal brilliance if the screw is at ground potential.

The following adjustments should be made when a complete
realignment is required or a new picture tube is installed.
These adjustments should be performed with rated power
supply voltage unless otherwise noted.
13-1. BEAM LANDING!
Preparation:
• Feed in the white pattern.
• Before starting, degauss the entire screen.
1. Loosen deflection yoke screw.
2. Position neck ass'y as shown in Fig. 3-1.
3. Adjust purity control as shown in Fig. 3-2.
4. Slide deflection yoke as far forward as it will
go.
5. Turn the raster signal of the pattern generator to
red.
6. Adjust purity control to center vertical red band
as shown in Fig. 3-3.
7. Slide deflection yoke back for a uniform red
screen.
8. Check green and blue rasters for uniformity by
performing the same way as steps 5 ,6 and 7.
9. Tighten the deflection yoke screw.
10. Check if mislandihg appears at corners a - d as
shown in Fig. 3-4. If mislanding is observed,
correct it as shown in Fig. 3-4.
11. Confirm that beam landing is correct when the
receiver is faced in all directions.
Perform the adjustments in order as follows:
1. Beam Landing
2. Convergence
3. SCREEN and White Balance
Note: Test Equipment Required.

If blue dot does not coincide with red and green
dot, perform following steps.
Move BMC magnet (a) to correct insufficient H.

I DYNAMIC CONVERGENCE Adjustment I
Preparation:
• Before starting, perform Horizontal and Vertical
Static Convergence Adjustment.
l. Loosen deflection yoke screw.
2. Remove deflection yoke spacers.
3. Move the deflection yoke for best convergence.
4. Tighten the deflection yoke screw.
5. Install the deflection yoke spacers.
6. Adjust the Y.CROSS (RV2505) and Y. BOW
(RV2503), so that RED and BLUE shown in Fig.-
I will become a=b=c.

the screen with H ST AT YR
8. Adjust the CORNER BOW(RV2504), so that
RED and BLUE shown in Fig.-2 will become a=
b=c and d=e=f.
Note: At this point, if the relationship between a=c
or d=f is not established adjust the Y • CROSS
(RV2505) again.

12. Match the horizontal convergence at the center of
the screen with the H ST AT YR
13. When the H AMP is adjusted repeat the pro-
cedures described in Steps 5 to 7.
14. If divergence of the convergence exists at the corner
of the screen. the adjustments described in Steps
after 3 should be repeated.

WHITE BALANCE ADJUSTMENT
1) SCREEN (G
1. Confirm that G
2. Adjust CUT OFF VR (R,B) so that R,B cathode
voltage becomes 180 V DC.
Adjust with G2 VT ( R V701) immediately prior
to the disappearing of the luminscent line.
2) W /B adjustment
1. Input a all white signal.
2. Set the PICTURE control to minimum and turn
the BRIGHT control mechanical center.
3. Set RV705 CUT OFF (R,B) and RV703 (CUT
OFF) to minimum.
4. Turn RV701 (SUB BRT) slowly to obtain a
faintly visible cross-hatch.
Note the color that first becomes visible by
turning R V701.
5. Adjust the other two BKG controls for best
white balance (neutral gray) of the faint corss-
hatch.
6. Set the rICTURE control fully clockwise .
Observe the screen and adjust the RV3301
(B ,IK), RV3302 (G,IK) controls for best white
balance.
7. Repeat steps 1, through 7.
