Component Connections/ Screen Color
- If the color on your TV screen is not correct or the black and white colors are off, run Start Picture Test.
- If the test results indicate that the problem is not caused by the TV, do the following: When using the One Connect, confirm that its video input connectors are connected to the correct external device video output connectors. When using the component cable, confirm that the green (Y), blue (Pb), and red (Pr) jacks are plugged into their proper connectors. For more information about how to connect an external device, run Connection Guide.
Screen Brightness
- If the colors on your TV are correct but just a little too dark or bright, try adjusting the following settings first.
Blurring, or Juddering
- If you notice blurring or juddering on the screen, use the Auto Motion Plus Settings function to resolve the issue.
Unwanted Powering Off
- If your TV appears to turn off by itself, try disabling some of the TV's energy efficiency functions.
See if Sleep Timer has been enabled. The Sleep Timer automatically turns the TV off after a specified period of time.
- If the Sleep Timer has not been enabled, see if Auto Power Off or Off Timer has been enabled and disable it.
Problems Powering On
- If you are having problems powering on your TV, there are a number of things to check before calling the service department.
Confirm that the TV's power cord is connected correctly at both ends and that the remote control is operating normally.
Make sure that the antenna cable or cable TV cable is firmly connected.
If you have a cable box or satellite box, confirm that it is plugged in and turned on.
Unable to find a Channel
- If your TV is not connected to a cable box or satellite box, run Auto Program.
The TV image does not look as good as it did in the store.
- Store displays are tuned to a digital UHD channel or HD channel.
If you are using analog cable, upgrade to digital cable.
If you use an analog cable box or satellite box, upgrade to a digital cable box or satellite box and adjust the digital cable box and satellite box's video output resolution to UHD or HD.
Be sure to use an HDMI cable to enjoy high quality videos.
To connect the TV with your PC, make sure that your PC's graphic card supports UHD resolutions.
For more information about the supported UHD resolutions, refer to "Supported Resolutions for UHD Input Signals."
The picture is distorted.
The compression of video content may cause picture distortions, especially in fast moving pictures from sports programs and action movies. If the signal reception is weak or poor, screen distortion may be visible but it is not a malfunction. Mobile phones used close to the TV (within 3.2 ft) may cause noise on analog and digital channels.
The color is wrong or missing.
If you’re using a Component connection, make sure that the Component cables are connected to the correct jacks. Incorrect or loose connections may cause color problems or a blank screen
The color is poor or the picture is not bright enough.
Go to Picture and then adjust the Picture Mode, Brightness, Sharpness, and Color settings.
See if Power Saving Mode has been enabled.
Try resetting the picture.
There is a dotted line on the edge of the screen.

The picture is good but there is no sound.
Set Sound Output to TV Speaker
If you are using an external device, check the device’s audio output option.
For example, you may need to change your cable box’s audio option to HDMI if the box connected to your TV is using an HDMI cable.
To listen to computer sound, connect an external speaker to the computer’s audio output connector.
If your TV has a headphone jack, make sure there is nothing plugged into it.
Reboot the connected device by disconnecting and then reconnecting the device’s power cable.
No sound is heard.
