Troubleshooting about new functions 

Problem

AllShare (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.

AllShare (Notication)•

Can all devices with the DLNA function be recognized through Notication?

Can I use all the services related to DLNA?

The notication screen that appears after a device connects disappears within a few seconds. How can I access this connected device again?

AllShare (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 Notication.

Presently, you can only use the services related to ScreenShare and MediaPlay. • We will launch a new DLNA service in the future.

The DLNA Notication 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. Conrm 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.4. If the RUIS on the cell phone is enabled, please disable it and then enable it again.5.

Problem

AllShare (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 conrm 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 conrm 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.

4-2. Alignments and Adjustments

4-2-1. General Alignment instruction

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 specied 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 specied 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.
