1. Precautions
1-1 Safety Precautions
1. Be sure that all of the built-in protective
devices are replaced. Restore any missing
protective shields.
2. When reinstalling the chassis and its
assemblies, be sure to restore all protective
devices, including: nonmetallic control knobs
and compartment covers.
3. Make sure that there are no cabinet openings
through which people—particularly
children—might insert fingers and contact
dangerous voltages. Such openings include
the spacing between the picture tube and the
cabinet mask, excessively wide cabinet
ventilation slots, and improperly fitted back
covers.
If the measured resistance is less than 1.0
megohm or greater than 5.2 megohms, an
abnormality exists that must be corrected
before the unit is returned to the customer.
4. Leakage Current Hot Check (Figure 1-1):
Warning: Do not use an isolation
transformer during this test. Use a leakage-
current tester or a metering system that
complies with American National Standards
Institute (ANIS C101.1, Leakage Current for
Appliances), and Underwriters Laboratories
(UL Publication UL1410, 59.7).
5. With the unit completely reassembled, plug
the AC line cord directly into the power
outlet. With the unit’s AC switch first in the
ON position and then OFF, measure the
current between a known earth ground (metal
water pipe, conduit, etc.) and all exposed
metal parts, including: antennas, handle
brackets, metal cabinets, screwheads and
control shafts. The current measured should
not exceed 0.5 milliamp. Reverse the power-
plug prongs in the AC outlet and repeat the
test.
Fig. 1-1 AC Leakage Test
6. Antenna Cold Check:
With the unit’s AC plug disconnected from the
AC source, connect an electrical jumper across
the two AC prongs. Connect one lead of the
ohmmeter to an AC prong. Connect the other
lead to the coaxial connector.
7. X-ray Limits:
The picture tube is especially designed to pro-
hibit X-ray emissions. To ensure continued
X-ray protection, replace the picture tube only
with one that is the same type as the original.
Carefully reinstall the picture tube shields and
mounting hardware; these also provide X-ray
protection.
8. High Voltage Limits:
High voltage must be measured each time ser-
vicing is done on the B+, horizontal deflection
or high voltage circuits. Correct operation of
the X-ray protection circuits must be
reconfirmed whenever they are serviced.
(X-ray protection circuits also may be called
“horizontal disable” or “hold-down”.)
Heed the high voltage limits. These include
the X–ray Protection Specifications Label, and
the Product Safety and X-ray Warning Note on
the service data schematic.

9-1-1 Notes
The TV’s 1st and 2nd tuners (and VCR module) are “multi-system.” compatible:
IC201 (TDA8842/8841) is the video, chroma, and deflection (VCD) IC .
9-1-1(A) TAPE PLAYBACK (REGARDLESS OF ORIGINAL RECORDING SYSTEM)
If the output PB signal of micom pin 6 is high, the PB signal outputs from module deck 2, passes
through IC 702 pins 2 and 3 and out to another VCR . The output signal of IC701 pin 1 (pin 15)
outputs from IC201S pin 17 .
9-1-1(B) VIEWING NORMAL CHANNEL WHILE RECORDING A SCRAMBLED CHANNEL:
The output CVBS (Composite Video Signal) of the 2nd IF outputs to IC702pin 3 when the micom’s pin 7
V/T/H (VCR tuner high) is high . The decoded signal goes to IC701 pin 2, where it is fed to IC 701 pin
4 (high output of micom’s’ pin 8— AV/Tuner), and out to VCR pin 4 (module deck) for recording.
9-1-1(C) VIEWING A SCRAMBLED CHANNEL WHILE RECORDING AN UNSCRAMBLED CHANNEL.
The output CVBS of the 2nd IF is fed from IC701 pin 5 to IC701 pin 4 (low output of micom
pin 8—AV/tuner). Then it goes to the module deck pin 4 for recording.
The scrambled signal (CVBS) is fed to IC702 pin 1 through the 1st IF, and then to IC702 pin 3 (micom’s
pin 7, V/T/H registers low). Then it goes to the decoder input. The descrambled signal goes to IC701
pins 2 and 15 (PH high output of micom’s pin 6), and then to IC201S pin 17, where it outputs as RGB.
9-1-1(D) SYNCHRONOUS RECORDING:
The viewer sees the signal from the 1st tuner , while the signal from the second tuner is recorded.
Audio processing for the French system type is shown in the table.
