Solutions and Explanations
• Check cable connections (remove and reconnect all cables connected to the TV and external
devices).
• Set your external devices' (Cable/Set top Box, DVD, Blu-ray etc) video outputs to match the
connections to the TV input. For example, if an external device's output is HDMI, it should be
connected to an HDMI input on the TV.
• Make sure your connected devices are powered on.
• Be sure to select the TV's correct source by pressing the SOURCE button on the TV remote.
• Make sure the Antenna cable is connected securely.
• Please try Plug & Play (Initial setup) to add available channels to the channel list. Go to
Setup - Plug & Play (Initial setup) and wait for all available channels to be stored (p. 7).
• Verify the Antenna is positioned correctly.
• Compression of video contents may cause picture distortion, especially with fast moving pictures
such as sports and action movies.
• A low signal can cause picture distortion. This is not a TV issue.
• Set your PC's output resolution and frequency so they match the resolutions supported by the TV
(p. 29).
• This is normal; "PC" is always shown on the source list, regardless of whether a PC is connected.
• If you are using a HDMI connection, check the audio output setting on your PC.
• Samsung Wireless USB dongle is required to use a wireless network.
• Make sure the Network Connection is set to Wireless (p. 32).
• Make sure the TV is be connected to a wireless IP sharer (router).
• See the manual for the USB device to check that the USB device supports recording.
• If the USB device has a lock, ensure it is off.
• Check that the USB device can be formatted when connected to the PC. Connect the USB to the TV
and format it. (Formatting may fail intermittently.)
• If a Device Performance Test or formatting failed, it means that there is a problem with the USB
hardware or the performance of the USB hardware is too low.
• If the USB device has a lock, ensure it is off.
• Recover the USB device using the recovery function in Checking Device.
• Check that a USB device is connected.
• Check that the channel is a recordable digital channel.
• If the signal is weak or does not exist, the recording function will automatically be closed.
• The TV will not record if the USB device has no free memory space. Check that this is not the case.
• Check that a USB device is connected.
• Radio channels and analogue broadcasts are not supported.
• Data broadcast channels are not supported.
• If the signal is weak or does not exist, the Timeshift Mode function will automatically be closed.
• Timeshift Mode cannot be performed if the USB device has no free memory space. Check that this
is not the case.
• These problems may occur if you use a low-capacity USB device that does not support recording.
• We recommend using the USB HDD.
A scheduled recording is disabled for certain operations (formatting, performance test, error checking,
deleting) that access the file system of a USB device.
• If there is no USB device connected, the TV will not record even if the scheduled time is reached.
• The TV will not record if the USB device has no free memory space. Check that this is not the case.
• If you record a channel locked with Parental lock, the PIN input window will appear when you try to
play back the recording.
• If multiple recording devices are connected and the device set as Default Recording Device has no
free memory space, the recording function will be closed. Attempt recording again. The device with
the most free memory space will automatically be set as Default Recording Device and the TV will
start recording.
