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 leakagecurrent 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 powerplug 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 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.

8. High Voltage Limits: High voltage must be measured each time servicing 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.

Follow these safety, servicing and ESD precautions to prevent damage and protect against potential hazards such as electrical shock and X-rays.

1-1 Safety Precautions (Continued)

9. 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.

10. 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.

11. 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.

12. 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.

13. 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.

14. Components, parts and wiring that appear to have overheated or that are otherwise damaged should be replaced with parts that meet the original specifications. Always determine the cause of damage or overheating, and correct any potential hazards.

15. 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, 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.

16. 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.

17. 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.

18. 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. A replacement part that does not have the same safety characteristics as the original might create shock, fire or other hazards.

Precautions

1-2 Servicing Precautions

1. Servicing precautions are printed on the cabinet. Follow them.

2. Always unplug the unit’s AC power cord from the AC power source before attempting to: (a) Remove or reinstall any component or assembly, (b) Disconnect an electrical plug or connector, (c) Connect a test component in parallel with an electrolytic capacitor.

3. Some components are raised above the printed circuit board for safety. An insulation tube or tape is sometimes used. The internal wiring is sometimes clamped to prevent contact with thermally hot components. Reinstall all such elements to their original position.

4. After servicing, always check that the screws, components and wiring have been correctly reinstalled. Make sure that the portion around the serviced part has not been damaged.

5. Check the insulation between the blades of the AC plug and accessible conductive parts (examples: metal panels, input terminals and earphone jacks).

6. Insulation Checking Procedure: Disconnect the power cord from the AC source and turn the power switch ON. Connect an insulation resistance meter (500V) to the blades of the AC plug.

The insulation resistance between each blade of the AC plug and accessible conductive parts (see above) should be greater than 1 megohm.

7. 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.

8. 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.

9. When some parts inside the optical engine (except lamp) are damaged, replace the whole optical engine.

Precautions

Samsung Electronics 1-3

Warning1: First read the “Safety Precautions” section of this manual. If some unforeseen circumstance creates a conflict between

the servicing and safety precautions, always follow the safety precautions.

Warning2: An electrolytic capacitor installed with the wrong polarity might explode.

WARNING : This cover is provided with an interlock to reduce

the risk of excessive ultraviolet radiation. Do not defeat its purpose or atempt to service without removing cover completely.

CAUTION : Replace with same type numer DS001AKB

1. 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.

2. Immediately before handling any semicon ductor 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.)

3. After removing an ESD-equipped assembly, place it on a conductive surface such as aluminum foil to prevent accumulation of electrostatic charge.

4. Do not use freon-propelled chemicals. These can generate electrical charges that damage ESDs.

5. Use only a grounded-tip soldering iron when soldering or unsoldering ESDs.

6. Use only an anti-static solder removal device. Many solder removal devices are not rated as “anti-static”; these can accumulate sufficient electrical charge to damage ESDs.

7. Do not remove a replacement ESD from its protective package until you are ready to install it. Most replacement ESDs are packaged with leads that are electrically shorted together by conductive foam, aluminum foil or other conductive materials.

8. Immediately before removing the protective material from the leads of a replacement ESD, touch the protective material to the chassis or circuit assembly into which the device will be installed.

9. Minimize body motions when handling unpackaged replacement ESDs. Motions such as brushing clothes together, or lifting a foot from a carpeted floor can generate enough static electricity to damage an ESD.

Ballast CN1 terminal

*When measuring voltage,

make sure to measure the

voltage between the two

terminals.

1. If the 3 LED indicators flicker from the time the set is

turned on, it means:

1) The CN106 connector on the DMD board is not inserted

properly.

2) The MDR cable that connects the DIGITAL board to the

DMD board is not connected properly.

3) If the lamp does not turn on even after turning it on three

times, by powering off/on 15 second intervals:

! The B+ 380V power is not supplied to the ballast

(The cable is not connected properly between the power

and the ballast.)

@ The cable connected to the CN110 terminal on the

DMD board and the CN2 terminal on the ballast is short-

circuited or not connected.

# The lamp does not turn on because 5V has not been

supplied to blue pin #1 on the CN2 terminal of the

ballast.

$ 5V is supplied to the CN2 terminal on the ballast but the

lamp does not turn on because the ballast has a failure.

(If the lamp is replaced and 5V is supplied normally to

the CN2 terminal, suspect a ballast failure if the lamp still

does not turn on.)

% The ballast is normal but the lamp doest not turn on.

(When 5V is supplied to CN2 and 385V to CN1, but the

lamp does not turn on, try replacing the lamp. If it turns

on, that means it was a lamp failure.)

4) The color wheel engaged to the engine does not operate,

or the connector which indicates the operation of the

color wheel is not connected properly, and therefore

does not allow the lamp to turn on. The cause can be

determined when the set still does not turn on after

attempting to turn it on three times.

5) Another digital board or the DMD board has a failure.

Conclusively, if the three LED indicators flicker, first

check the above five items, then check the various

connector connections, and then suspect a failure of the

lamp or the ballast.

Failure if the LED indicator is normal but the screen is not displayed.

First

Check whether the External LED

indicator of the set is normal.

Only the Lamp LED indicator should be turned on.

Second

Third

Check whether the DIGITAL board

LED indicators inside the set are lit.

All of the three LED indicators should be turned on.

* You can observe those LED indicators through the cabinet holes

at the back of the set. All three LED indicators should be turned on.

Check whether the set

lamp is turned on.

When the lamp is turned off, replace it.

* When you turn on the set again after replacing the lamp,

- It should turn on within 30 seconds. (For 50 and 61 inch TVs)

*If more than one minute passes before it turns on, or if it does not

turn on, replace both the ballast within the engine and the lamp.

Check the lamp.

Repair plan

Press the switch to cause a short.

On the right side of

the back of the set.

1. Check whether 5V is supplied to the blue terminal of CN2

2. Check whether DC 380V is supplied to both end

terminals of CN1

1) If 5V is applied to the CN2 terminal of the ballast,

but the lamp does not turn on, replace the ballast.

2) When 5V is not supplied, replace first the engine.

If the lamp still does not work, replace the DMD

board attached to the engine.

* For repair methods of the DMD board, refer to

separate instructions.

Check the signal supply procedure.

[Check whether the signals are supplied from the

analog board to the digital board]

Method for inspecting whether signals are

being supplied from the digital board to

the DMD board

DMD board inspection method

1) Check in which mode the screen does not display.

2) If the RF, VIDEO, DVD, or DTV mode screen

does not display, check the Analog CN511 termi-

nals, Digital CN309 connector connections, and

their signaling.

3) If the DVI or PC mode screen does not display,

replace and inspect the digital board.

4) If the screen does not display in any mode, check

whether the signals are being output from the

digital board.

Check the output of the IC314 terminal.

If the signal output state is normal, susp-

ect the DMD board.

* Refer to the Digital Board Description

Diagram.

1) Check whether +26V and -26V is being supplied to

the DMD board.

-> If the voltage is abnormal, replace the tantal cond-

enser (C116, C110: When failure occurs intermittently.)

If the problem continues after replacement, then rep-

lace the power drive IC (IC108).

2) If the DMD voltage is normal, replace the panel, or

reassemble the panel.

(Try to fix the four silver screws again.)
