1. 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 : 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 (See Fig. 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 (ANSI 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 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.
6. X-ray Limits : The picture tube is designed to prohibit X-ray emissions. To ensure continued X-ray protection, replace the picture tube only with one that is the same type as the original.
Fig. 1-1 AC Leakage Test
7. 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.
8. High Voltage Limit : High voltage must be measured each time servicing is done on the B+, horizontal deflection or high voltage circuits.
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. Some semiconductor (“solid state”) devices are easily damaged by static electricity. Such components are called Electrostatically Sensitive Devices (ESDs); examples include integrated circuits and some field-effect transistors. The following techniques will reduce the occurrence of component damage caused by static electricity.
10. Immediately before handling any semiconductor
components or assemblies, drain the electrostatic charge from your body by touching a known earth ground. Alternatively, wear a discharging Wrist-strap device. (Be sure to remove it prior to applying power--this is an electric shock precaution.)

Precautions
1-2 Samsung Electronics
11. High voltage is maintained within specified limits by close-tolerance, safety-related components and adjustments. If the high voltage exceeds the specified limits, check each of the special components.
12. Design Alteration Warning : Never alter or add to the mechanical or electrical design of this unit. Example : Do not add auxiliary audio or video connectors. Such alterations might create a safety hazard. Also, any design changes or additions will void the manufacturer’s warranty.
13. Hot Chassis Warning : Some TV receiver chassis are electrically connected directly to one conductor of the AC power cord. If an isolation transformer is not used, these units may be safely serviced only if the AC power plug is inserted so that the chassis is connected to the ground side of the AC source.
To confirm that the AC power plug is inserted correctly, do the following : Using an AC voltmeter, measure the voltage between the chassis and a known earth ground. If the reading is greater than 1.0V, remove the AC power plug, reverse its polarity and reinsert. Re-measure the voltage between the chassis and ground.
14. Some TV chassis are designed to operate with 85 volts AC between chassis and ground, regardless of the AC plug polarity. These units can be safely serviced only if an isolation transformer inserted between the receiver and the power source.
15. Never defeat any of the B+ voltage interlocks. Do not apply AC power to the unit (or any of its assemblies) unless all solid-state heat sinks are correctly installed.
16. Always connect a test instrument’s ground lead to the instrument chassis ground before connecting the positive lead; always remove the instrument’s ground lead last.
17. Observe the original lead dress, especially near the following areas : Antenna wiring, sharp edges, and especially the AC and high voltage power supplies. Always inspect for pinched, out­of-place, or frayed wiring. Do not change the spacing between components and the printed circuit board. Check the AC power cord for damage. Make sure that leads and components do not touch thermally hot parts.
18. Picture Tube Implosion Warning : The picture tube in this receiver employs “integral implosion” protection. To ensure continued implosion protection, make sure that the replacement picture tube is the same as the original.
19. Do not remove, install or handle the picture tube without first putting on shatterproof goggles equipped with side shields. Never handle the picture tube by its neck. Some “in-line” picture tubes are equipped with a permanently attached deflection yoke; do not try to remove such “permanently attached” yokes from the picture tube.
20. Product Safety Notice : Some electrical and mechanical parts have special safety-related characteristics which might not be obvious from visual inspection. These safety features and the protection they give might be lost if the replacement component differs from the original--even if the replacement is rated for higher voltage, wattage, etc.
Components that are critical for safety are indicated in the circuit diagram by shading, ( or ). Use replacement components that have the same ratings, especially for flame resistance and dielectric strength specifications. Areplacement part that does not have the same safety characteristics as the original might create shock, fire or other hazards.

3-4-3 Maintenance
Carry out the following periodic maintenance checks in order to fully exercise all functions, operations and tape. After repairing, service the set as follows:
1) Cleaning of Drum Assembly
Œ Gently apply lens tissue soaked in ethyl alcohol to the Drum assembly.
Clean the Upper Drum assembly while rotating it slowly counterclockwise(by hand).
Note : Do not rotate the motor by power or rotate the Upper Drum assembly clockwise.
Also, the Head tip will be damaged if the lens tissue is moved in a perpendicular direction. Be sure to follow these instructions when cleaning the Drum Ass’y
2) Cleaning of Tape Path
Œ In EJECT mode, clean the tape path system(from Pole Tension P1 through Pole Review P8, Pinch Roller and
Capstan Shaft) and the Lower Drum. Using the lens tissue soaked in ethyl alcohol.
Note : Make sure that no oil or grease adheres to the lens tissue.

3-4-4 Mechanical Check and Adjustment
3-4-4(a) Tension Regulator Adjustment
1) Disassembly
Œ For the removal of the Housing Ass’y refer to 4-2-2 (page 4-6).
2) Adjustment
Œ Set to PLAY mode (without cassette tape). ´ Check that the distance between external surface of Holder Loading and extenal diamater of Arm Tension is
0.7±0.3mm. (Fig. 3-17)
ˇ If necessary, proceed to step 4. ¨ If the Arm Tension Œ is located inside (or right) the position specified, adjust the Cap Adjust Œ toward
arrow “A”. (If it is located outside (or left), adjust toward arrow “B”.)
Note : Check if the Arm Tension can be moved toward arrow “C” in PB mode.
3) Reassembly
Œ For the removal of the Housing Ass’y refer to 4-2-2 (page 4-6).

3-4-5 Tape Path Adjustment
3-4-5(a) Preparation for Adjustment
Œ Clean the tape running surface (Poles, Drum, Capstan Shaft, Pinch Roller). ´ Observe the PB RF signal and Head Switching Pulse on an oscilloscope. ˇ Play back the alignment tape. ¨ Check that the waveform of the RF signal is flat at both inlet and outlet(A in Fig. 3-21).
If not flat (B or C in Fig. 3-21), do adjustments 3-4-5(b) through 3-4-5(d).

ˇ Confirm that no large fluctuation occur on the waveform. (Fig. 3-26)
2) CUE and REV Check
Œ Playback the alignment tape, and set to REV mode.
Confirm that the waveform peaks have a uniform Pitch. (Fig. 3-27 A) If the track pitch is not uniform, do section 3-4-5(b) (Tracking adjustment) and 3-4-5(c) (P8 adjustment).
´ Set to CUE mode.
Confirm that the waveform peaks still have a uniform pitch. (Fig. 3-27 B) If the track pitch is not uniform, do section 3-4-5(b) (Tracking Adjustment).
