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)

GENERAL
The instructions mentioned here are partial abstracts from the Operating Instruction Manual.
The page numbers shown reflect those of the Operating Instruction Manual.

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.
Cable box and cable
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 26)
· When using PIP, you cannot view the
AUX input in the window picture.

VCR Connections
Connecting an antenna/cable TV
system with a VCR
1 Attach the coaxial connector from your
cable or antenna to IN on your VCR.
2 Using A/V connectors, connect AUDIO
and VIDEO OUT on your VCR to AUDIO
and VIDEO IN on your TV*.
3 Using a coaxial connector, connect OUT on
your VCR to VHF/UHF on your TV.
* If you are connecting a monaural VCR, connect only the
single white audio output to the left input on your TV.
Connecting a VCR and TV with a
cable box
1 Connect the single (input) jack of the
Splitter to your incoming cable connection,
and connect the other two (output) jacks
(using coaxial cable) to IN on your cable
box and VHF/UHF on your TV.
2 Using a coaxial connector, connect OUT on
your cable box to IN on your VCR.
3 Using A/V connectors, connect AUDIO and
VIDEO OUT on your VCR to AUDIO and
VIDEO IN on your TV.

does not provide sound, your audio
connectors must still be connected.

Connecting two VCRs
MONITOR OUT gives you the ability to use a
second VCR to record a program being played
by the primary VCR or to perform tape
editing and dubbing.
1 Connect the VCR intended for playback
using the connection instructions on page
4 of this manual.
2 Using A/V connectors, connect AUDIO
and VIDEO IN on your VCR intended for
recording to MONITOR AUDIO and
VIDEO OUT on your TV.
Notes
· If you will be connecting your A/V
receiver to external speakers, you do not
need to connect AUDIO OUT on your
A/V receiver to AUDIO IN on your TV.
· You cannot record signals from equipment
connected to the Y, PB, PR input.
