SAFETY CHECK-OUT
After correcting the original service problem, perform the
following safety checks before releasing the set to the
customer:
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 microampere).
Leakage current can be measured by any one of three methods.
1. A commercial leakage tester, such as the Simpson 229 or
RCA WT-540A. Follow the manufacturers' instructions to
use these instructions.
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's 250 and Sanwa
SH-63Trd are examples of passive VOMs that are suitable.
Nearly all battery operated digital multimeters that have a
2V AC range are suitable. (See Fig. A)
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.
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
cold-water pipe with an ohmmeter. The reading should be zero
ohms. If a cold-water pipe is not accessible, connect a 60-l00 watts
trouble light (not a neon lamp) between the hot side of the re-
ceptacle 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. (See Fig. B)

for viewing both local and cable channels.
Select cable or antenna mode by pressing
ANT on the remote control. You will be able
to alternate between the two input sources.
Note
· In order to receive channels with an
antenna, you will need to turn your CABLE
to OFF (see page 26) and perform the
AUTO PROGRAM function.

Connecting and Installing the TV (continued)
Cable Box Connections
Some pay cable TV systems use scrambled or
encoded signals that require a cable box to
view all channels.
Cable box
1 Connect the coaxial connector from your
cable to the IN on your cable box.
2 Using a coaxial cable, connect OUT on
your cable box to VHF/UHF on your TV.

For this set up, you can switch between
scrambled channels (through your cable box),
and normal (CATV) channels by pressing
ANT on your remote control.
Notes
· Your Sony remote control can be
programmed to operate your cable box.
(see page 32)
· When using PIP, you cannot view the
AUX input in the window picture.

initial set up. It shows how to connect to
your antenna or cable, and connect any
accessories or components.
2 Basic Set Up
This section teaches you the basic skills
needed to operate your new TV. It shows
you how to operate special functions of
the remote control.
3 Using your New TV
This section shows you how to begin
using your new TV. It shows how to use
the Easy Set Up Guide feature, and how to
use your remote control.
4 Using your Menus
This section teaches you how to access
on-screen menus and adjust your TV's
settings.
Instructions in this manual are written for the
remote control. Similar controls may be found on
the TV console.
Safety
· Operate the TV only with 120 V AC .
· The plug is designed, for safety purposes,
to fit in the wall outlet only one way. If
you are unable to insert the plug fully into
the outlet, contact your dealer.
· If any liquid or solid object should fall
inside the cabinet, unplug the TV
immediately and have it checked by
qualified personnel before operating it
further.
· If you will not be using the TV for several
days, disconnect power by pulling the
plug itself. Never pull on the cord.
For details concerning safety precautions, see the
supplied leaflet "IMPORTANT SAFEGUARDS".
Installing
· To prevent internal heat build-up, do not
block the ventilation openings.
· Do not install the TV in a hot or humid
place, or in a place subject to excessive
dust or mechanical vibration.
