Issues Solutions and Explanations
No Picture, No Video
The TV won’t turn on. • Make sure the AC power cord is securely plugged in to the wall outlet and the TV.
• Make sure the wall outlet is working.
• Try pressing the POWER button on the TV to make sure the problem is not the remote. If the TV turns
on, refer to “The remote control does not work” below.
The TV turns off automatically. • Ensure the Sleep Timer is set to Off in the Setup menu. (p. 25)
• If your PC is connected to the TV, check your PC power settings.
• Make sure the AC power cord is plugged in securely to the wall outlet and the TV.
• When watching TV from an antenna or cable connection, the TV will turn off after 10 ~ 15 minutes if
there is no signal.
There is no picture/Video. • 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.
RF(Cable/Antenna) Connection
The TV is not receiving all channels. • Make sure the Antenna cable is connected securely.
• Please try Plug & Play (Initial setup) to add available channels to the channel list. Go to MENU -
Setup - Plug & Play (Initial setup) and wait for all available channels to be stored (p. 7).
• Verify the Antenna is positioned correctly.
The picture is distorted: macro block error
small block, dots, pixelization
• 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.
PC Connection
A “Mode Not Supported” message
appears.
• Set your PC’s output resolution and frequency so they match the resolutions supported by the TV
(p. 29).
“PC” is always shown on the source list,
even if a PC is not connected.
• This is normal; “PC” is always shown on the source list, regardless of whether a PC is connected.
The video is OK but there is no audio. • If you are using a HDMI connection, check the audio output setting on your PC.
Network Connection (Depending on Models)
Wireless network connection failed. • 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).
Recording / Timeshift
The USB device is not recognized or a
Device Format, Device Test or Device
Performance Test fails.
• 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.
A message prompts me to format a USB
device that has been working well. • If the USB device has a lock, ensure it is off.
• Recover the USB device using the recovery function in Checking Device.
The recording function does not work. • 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.
Timeshift Mode does not work. • 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.
A message indicates a performance test
failure, and the recording and
Timeshift Mode functions do not work.
• These problems may occur if you use a low-performance USB device that does not support
recording. We recommend using a USB HDD with at least 5 400 rpm, but a USB HDD of RAID type
is not supported.
