This Service Manual is a property of Samsung Electronics Co.,Ltd.
Any unauthorized use of Manual can be punished under applicable
International and/or domestic law.
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 LED TV
When servicing the LED 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 LED 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 LED TV.
2.
Inspect all protective devices such as nonmetallic control knobs, insulating materials, cabinet backs, adjustment and
compartment covers or shields, isolation resistorcapacitor networks, mechanical insulators, etc.
3.
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 (ANSI
C101.1, Leakage Current for Appliances), and Underwriters Laboratories (UL Publication UL1410, 59.7).

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
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.

1-2. 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.
2.
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.
3.
After servicing, always check that the screws, components and wiring have been correctly reinstalled. Make sure that
the area around the serviced part has not been damaged.
4.
Check the insulation between the blades of the AC plug and accessible conductive parts (examples: metal panels,
input terminals and earphone jacks).
5.
Insulation Checking Procedure: Disconnect the power cord from the AC source and turn the power switch ON.
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.
6.
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.
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 LED TV.
2.
After removing an ESD-equipped assembly, place it on a conductive surface such as aluminum foil to prevent
accumulation of an electrostatic charge.
3.
Do not use freon-propelled chemicals. These can generate electrical charges sufcient to damage ESDs.
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.
6.
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.
7.
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.
Caution: Be sure no power is applied to the chassis or circuit and observe all other safety precautions.
8.
Minimize body motions when handling unpackaged replacement ESDs. Motions such as brushing clothes together,
or lifting your foot from a carpeted oor can generate enough static electricity to damage an ESD.

AllShare•
Problem
General•
I see no device connected to AllShare.
I tried to play a video from my cell phone
using the Connected Home function on the
Samsung TV but the video would not display
on the TV.
A video that can be played on my cell phone
cannot be played on my TV.
I cannot resume playback of a video using
Connected Home.
When I play a video through Connected
Home, I get intermittent picture loss.
Possible Solution
To use a device connected to AllShare, the device must be connected to PC •
Share Manager which is the DLNA server for MediaPlay and to a cell phone that
has the Connected Home or Screen Share function which are found on Samsung
Smartphones.
Check that the PC Share Manager is enabled, the Samsung TV is set to allow
•
connections and the ScreenShare function on the connected cell phone is enabled.
To use the cell phone’s Connected Home function, check that the shared folder is
•
set and the Share mode is ‘On.’
When a video is transmitted from Connected Home to a TV for the rst time, the •
settings screen that allows transfer to a TV is displayed.
Check that the transfer was not set to be rejected on this settings screen. If you
•
have set the cell phone to ‘Blocked’ in the ‘Media’ options of the AllShare settings,
please change the setting to ‘Unblocked’ and retry.
Please check the resolution and display format provided by MediaPlay of the TV.•
The resuming function is not supported for a video played on a cell phone.•
An 801.11b/g bandwidth network is used between a cell phone and a sharing •
device. There may be frequent buffering for HD quality videos, this also depends
on the condition of the wireless connection.
Please optimize your wireless Internet environment settings (avoid using wireless
•
Internet or bluetooth altogether if possible) or lower the picture quality of the video.
Notication•
Can all devices with the DLNA function be
recognized through Notication?
Can I use all the services related to DLNA?
The notication screen that appears after
a device connects disappears within a few
seconds.
How can I access this connected device
again?
ScreenShare Client•
I cannot nd the RUIS on my cell phone.
Only Samsung software and devices with the DLNA server function can be •
recognized through Notication.
Presently, you can only use the services related to ScreenShare and MediaPlay. •
We will launch a new DLNA service in the future.
The DLNA Notication is only displayed when a device is rst connected to a TV. •
To access the device again, please use the AllShare menu.
Check that the cell phone is connected to the wireless sharing device correctly.1.
Check that the DTV is connected either using a network cable or wirelessly to the 2.
wireless sharing device correctly.
Conrm the IP address and subnet mask to ensure that the cell phone and DTV
3.
are connected to the same network.
Check that the RUIS on the cell phone is enabled.

Problem
ScreenShare Server•
I cannot nd the remote control service
provided by the ScreenShare Server from the
ScreenShare Client.
The DTV did not update after pressing
buttons on the remote control that uses the
remote control service on the ScreenShare
Client.
Possible Solution
Check that the ScreenShare Client device is correctly connected to the network of 1.
the sharing device that the DTV is connected to.
Run network test in the network setup menu and conrm that MAC Address, IP
2.
Address, Subnet, Gateway, DNS Server and Gateway Ping each shows a success
message.
In the network setup menu, check that the ScreenShare Client and ScreenShare
3.
Server are on the same subnet.
- You can conrm they are on the same subnet by checking the IP address,
subnet mask and gateway address of the TV and ScreenShare Client as follows:
- If the IP address of the DTV is 10.88.83.4 and the subnet mask is 255.255.255.0,
the rst six digits of the ScreenShare Client’s IP address must be the same
(10.88.83) as that of the DTV, and the subnet mask and gateway address must
be the same as the DTV.
- If the IP address of the DTV is 10.88.83.4 and the subnet mask is 255.255.0.0,
the rst four digits of the ScreenShare Client’s IP address must be the same
(10.88) as that of the DTV, and the subnet mask and gateway address must be
the same as the DTV.
Move from the Allshare screen to the Setup screen, and open the Setup menu to 4.
check if the ScreenShare Client is connected to the same ScreenShare Server as
the TV name shown in the Setup options.
Move from the Allshare screen to the Setup screen, and open ScreenShare to
5.
check that the device, ScreenShare Client, is found on the list at the right side and
is set to “Allowed."
Check that the TV is turned on. •
You cannot turn on the TV using the remote control service (on the ScreenShare)
when the TV is turned off.

address.)
If the IP address the user entered in is invalid, change it to a valid IP address.
Check that the network cable is connected to the TV correctly.1.
If the TV is connected correctly, check whether the IP address is automatic or 2.
manual.
If the IP is automatic and connected to a sharing device, check the settings of the
3.
sharing device (AP) that is using a cable connection, or consult the corresponding
Internet service provider.
If the IP is manual, check if the IP address is entered correctly.
4.
(Here, the user should conrm if the manual IP address entered in is valid.)
If an encryption key must be entered in to connect to a sharing device, please 1.
check that the correct password set for the sharing device is entered.
Search surrounding sharing devices to see if there is a sharing device with the
2.
same SSID by selecting [Wireless Network Setup] and [Select Network].
If there is a sharing device with the same SSID, try to connect to this device.
If the IP address is set to automatic and you cannot connect to the sharing

device using option 1 or 2, check the settings of the sharing device to see if the
DHCP server function on the sharing device is enabled. If disabled, activate the
function. (For details on how to set up the sharing device, see the manual for the
corresponding sharing device.)
If you still cannot connect to the sharing device after conrming options 1, 2 and 3,
4.
reset the sharing device and try again.
When using a wireless network, the user’s
wireless sharing device cannot connect to
the PBC (WPS).
The auto-conguring sharing device cannot
be connected to automatically through a
wireless dongle.
(Here, the user’s sharing device must
support auto-conguration.)
Cannot connect to a wireless network (2) or
AP.
Check if the sharing device of the user supports WPS. 1.
(Refer to the manual of the sharing device.)
Check if the user pressed the PBC button on the sharing device.

If the sharing device of the user supports auto conguration, place the sharing
2.
device as close as possible to the wireless dongle on the TV and try to re-establish
the connection. (Must be placed close to the TV to establish a connection.)
There could be several causes of the connection failure. Check the AP settings to •
see if the following condition is found.
The Pure high-Throughput 802.11n mode (or Greeneld 802.11n mode) is selected
•
and the Encryption type is set to WEP, TKIP or TKIP-AES.
Under the conditions stated above, Samsung TVs will not support a connection in
•
compliance with new Wi-Fi certication specications. This is intended to maximize
the performance of the AP, TV and TV network.
To connect to the AP, set the Encryption type to AES. If Pure High-Throughput
802.11n mode (or Greeneld 802.11n mode) is selected and the Encryption type
is set to AES, your Samsung TV will connect to the AP providing you with optimum
performance.
