1. Precautions
1-1. Safety Precautions
Follow these safety, servicing and ESD precautions to prevent damage and to protect against potential hazards such as
electrical shock.
1-1-1. Warnings
For continued safety, do not attempt to modify the circuit board.1.
Disconnect the AC power and DC power jack before servicing.2.
1-1-2. Servicing the LCD TV
When servicing the LCD TV, Disconnect the AC line cord from the AC outlet.1.
It is essential that service technicians have an accurate voltage meter available at all times. 2.
Check the calibration of this meter periodically.
1-1-3. Fire and Shock Hazard
Before returning the LCD TV to the user, perform the following safety checks:
Inspect each lead dress to make certain that the leads are not pinched or that hardware is not lodged between the 1.
chassis and other metal parts in the LCD TV.
Inspect all protective devices such as nonmetallic control knobs, insulating materials, cabinet backs, adjustment and 2.
compartment covers or shields, isolation resistorcapacitor networks, mechanical insulators, etc.
Leakage Current Hot Check (Figure 1-1): 3.
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).

Figure 1-1. Leakage Current Test Circuit
With the unit completely reassembled, plug the AC line cord directly into a 120V AC outlet. With the unit’s AC switch 4.
rst 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: 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.
1-1-4. Product Safety Notices
Some electrical and mechanical parts have special safetyrelated characteristics which are often not evident from visual
inspection. The protection they give may not be obtained by replacing them with components rated for higher voltage,
wattage, etc. Parts that have special safety characteristics are identied by on schematics and parts lists. A substitute
replacement that does not have the same safety characteristics as the recommended replacement part might create
shock, re and/or other hazards. Product safety is under review continuously and new instructions are issued whenever
appropriate.

1. Precautions
1-2. Servicing Precautions
WARNING: An electrolytic capacitor installed with the wrong polarity might explode.
Caution: Before servicing units covered by this service manual, read and follow the Safety Precautions section of
this manual.
Note: If unforeseen circumstances create conict between the following servicing precautions and any of the
safety precautions, always follow the safety precautions.
1-2-1 General Servicing Precautions
Always unplug the unit’s AC power cord from the AC power source and disconnect the DC Power Jack before 1.
attempting to:
(a) remove or reinstall any component or assembly, (b) disconnect PCB plugs or connectors, (c) connect a test
component in parallel with an electrolytic capacitor.
Some components are raised above the printed circuit board for safety. An insulation tube or tape is sometimes 2.
used. The internal wiring is sometimes clamped to prevent contact with thermally hot components. Reinstall all such
elements to their original position.
After servicing, always check that the screws, components and wiring have been correctly reinstalled. Make sure that 3.
the area around the serviced part has not been damaged.
Check the insulation between the blades of the AC plug and accessible conductive parts (examples: metal panels, 4.
input terminals and earphone jacks).
Insulation Checking Procedure: Disconnect the power cord from the AC source and turn the power switch ON. 5.
Connect an insulation resistance meter (500 V) to theblades 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.
Always connect a test instrument’s ground lead to the instrument chassis ground before connecting the positive lead; 6.
always remove the instrument’s ground lead last.
Danger of explosion if battery is incorrectely replaced. Replace only with the same or equivalent type.7.
1-3. Electrostatically Sensitive Devices (ESD) Precautions
Some semiconductor (solid state) devices can be easily damaged by static electricity. Such components are commonly
called Electrostatically Sensitive Devices (ESD). Examples of typical ESD are integrated circuits and some eld-effect
transistors. The following techniques will reduce the incidence of component damage caused by static electricity.
Immediately before handling any semiconductor components or assemblies, drain the electrostatic charge from your 1.
body by touching a known earth ground. Alternatively, wear a discharging wrist-strap device. To avoid a shock hazard,
be sure to remove the wrist strap before applying power to the LCD TV.
After removing an ESD-equipped assembly, place it on a conductive surface such as aluminum foil to prevent 2.
accumulation of an electrostatic charge.
Do not use freon-propelled chemicals. These can generate electrical charges sufcient to damage ESDs.3.
Use only a grounded-tip soldering iron to solder or desolder ESDs.4.
Use only an anti-static solder removal device. Some solder removal devices not classied as “anti-static” can generate 5.
electrical charges sufcient to damage ESDs.
Do not remove a replacement ESD from its protective package until you are ready to install it. Most replacement ESDs 6.
are packaged with leads that are electrically shorted together by conductive foam, aluminum foil or other conductive
materials.
Immediately before removing the protective material from the leads of a replacement ESD, touch the protective 7.
material to the chassis or circuit assembly into which the device will be installed.
Caution: Be sure no power is applied to the chassis or circuit and observe all other safety precautions.
Minimize body motions when handling unpackaged replacement ESDs. Motions such as brushing clothes together, 8.
or lifting your foot from a carpeted oor can generate enough static electricity to damage an ESD.

4-2. Alignments and Adjustments
4-2-1. General Alignment Instuction
Usually, a color LCD-TV needs only slight touch-up adjustment upon installation. 1.
Check the basic characteristics such as height, horizontal and vertical sync.
Use the specied test equipment or its equivalent.2.
Correct impedance matching is essential.3.
Avoid overload. Excessive signal from a sweep generator might overload the front-end 4.
of the TV. When inserting signal markers, do not allow the marker generator to distort test result.
Connect the TV only to an AC power source with voltage and frequency as specied on 5.
the backcover nameplate.
Do not attempt to connect or disconnect any wire while the TV is turned on. Make sure 6.
that the power cord is disconnected before replacing any parts.
To protect against shock hazard, use an isolation transformer.7.

4-8-2 Hotel Option
Instruction
This TV is provided with interactive functionality through a set-back box (SBB/STB) connected to the TV, and with other
TVs in a computer controlled system for hotels and other hospitality businesses.
Interactive : When TV is powered-up initially it sends command to identify SBB/STB, if identied TV switches to ONLINE
mode and full control is through SBB/STB. In ONLINE TV stops receiving IR(Samsung remote) commands and acts
according to interface protocol.
Stand-Alone: If SBB/STB is not identied, TV should be switched to STAND-ALONE mode with restricted operation.
Operational Modes
When this TV (in Hotel mode) is operated with a SBB/STB, it is in one of two states
ONLINE or STAND-ALONE. In the STAND-ALONE state, the TV will act as a Hotel TV, but without active communication.
This is to prevent guests from trying to cheat the system by disconnecting the SBB/STB.
To set the details for Stand-alone or interactive mode, refer to page 15(Setting the hotel option data : Stand-alone mode
and Interactive mode)
- Some operations may be restricted to prevents guests from “cheating” the TV system.

4. Troubleshooting
RJP(Remote Jack Pack)
RJP stands for Remote Jack Pack. The RJP is a hardware module that has different Audio Video inputs (A/V, S-Video,
Audio, PC and HDMI) and corresponding outputs. The corresponding output sources are connected from RJP to TV.
The RJP communicates with the TV via RS232. Hot Plug & Play is a function that allows hotel guests to connect an
external source to the RJP. The RJP communicates with the TV by sending messages regarding Active/Inactive sources.
The TV will switch to the Active external source according to the priority set by the User.
- You have to connect the HDMI of the RJP to the HDMI 1 port of the TV.
- When the TV is on, connect the TV and the RJP within 10 seconds.
The RJP can be returned to the factory default settings by pressing the A/V and HDMI buttons simultaneously
for 10 seconds. All LEDs blink 5 times to Acknowledge that the rest has been performed.
The RJP will automatically turn off any LEDs after 5 minutes to avoid unnecessary light pollution in the hotel
room. The LEDs that were turned off will turn on again if the guest touches any of the buttons and the 5 minute
timer will restart. If the guest then touches another source button, the TV will change to the selected source and
the corresponding LED will be lit.
After an RJP Reset or a TV Power OFF/ON, it takes approx. 10 seconds to establish communications between
the TV and the RJP.
The following table shows the approximate time in seconds to switch from the TV to the input source, based on
the priority.
Scenario 1: When no inputs are connected.
Source To Connect
AV 2 Sec
PC 0.7 Sec
HDMI 3.9 Sec
Scenario 2: When two or more inputs are connected and an Input source is disconnected and then reconnected.
Source Disconnect To Connect Total
AV 4.5 Sec 2 Sec 6.5 Sec
PC 0.7 sec 0.7 Sec 1.4 Sec
HDMI 3.9 Sec 3.9 Sec 7.8 Sec
E.g. If the RJP has all its live sources AV, PC and HDMI connected, AV is viewed as the highest priority. If the RJP is in
HDMI mode, and a guest removes and reconnects the AV, the minimum time required to switch to the AV is 6.5 seconds.
To connect audio (Ipod or Mp), Music mode should be ON and Jack Ident detect should be OFF.
A/V, PC and HDMI input sources are supported.
