Below listed are few handling procedures :

● Scratch Damage:

Handle the display device with care to avoid scratching it.
● Moisture Damage:

Gently wipe off any moisture or let the device dry before using it.
● Dirt and Stain:

Gently wipe off the stain with a soft lint-free cloth.
● Temperature Difference:

High temperature and humidity will degrade the performance of a display device.
● Pressure and Heat:

Display device should be mounted 4 mm or more away from Printed Circuit Boards.
● Accessories Usage:

Use only attachments and accessories specified or recommended by Samsung.
● While Lightening:

Unplug the TV during lightning storms or when unused for long periods of time.
● Climate Change:

If the TV is moved from a cold place, do not turn it on for a few hours so any internal condensation can evaporate.
● Installation Procedure:

Install the TV upright on a horizontal, solid, flat surface away from excessive heat, dust, and vibration.

● Air Flow:

Keep a clearance of at least 10 cm (4 inches) between the vents on the back of the TV and nearby walls or enclosures.

 

Safety Precautions use before TV servicing and repairing

  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.

Warning: Do not use an isolation transformer during this test. Use a leakage current tester or a metering system.

  1. 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, screw heads 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.
  2. 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.

  1. X-ray Limits:

The picture tube is especially 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.

Carefully reinstall the picture tube shields and mounting hardware; these also provide X-ray protection.

  1. High Voltage Limits:

High voltage must be measured each time servicing is done on the B+, horizontal deflection or high voltage circuits.

The 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 higher voltage limits. These include the X-ray Protection Specifications Label, and the Product Safety and X-ray Warning Note on the service data schematic.

  1. High voltage is maintained within specified limits by close-tolerance, safety-related components or adjustments. If the high voltage exceeds the specified limits, check each of the special components.
  2. 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.

  1. 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 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.

  1. Some TV chassis are designed to operate with 85 volts AC between chassis and ground, regardless of the AC plug polarity.
  2. These units can be safely serviced only if an isolation transformer inserted between the receiver and the power source.
  3. Some TV chassis have a secondary ground system in addition to the main chassis ground.

This secondary ground system is not isolated from the AC power line. The two ground systems are electrically separated by insulating material that must not be defeated or altered.

  1. Components, parts or wiring that appear to have overheated or that are otherwise damaged should be replaced with parts that meet the original specifications.
  2. Always determine the cause of damage or overheating, and correct any potential hazards.
  3. Observe the original lead dress, especially near the following areas: Antenna wiring, sharp edges, and especially the AC and high voltage power supplies.
  4. Always inspect for pinched, out-of-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.
  5. 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.

  1. 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.
  2. 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.
  3. 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.
