Troubleshooting

Solutions and Explanations
If your Samsung Television is flickering or dimming sporadically, you may need to disable some of its
energy efficient features like the Eco Sensor or the Energy Saving feature. If you follow below step with your
remote, you can turn these features off or on.
• Energy saving: User Menu → System → Eco Solution → Energy Saving
• Eco Sensor: User Menu → System → Eco Solution → Eco Sensor
If you find that the color on your Samsung television's screen is not correct or black and White, first run a
Self Diagnosis on the TV to make sure there are no device issues.
• Self Diagnosis : User Menu → Support → Self Diagnosis → Picture Test
If the test is ok, try making sure ;
• Your connections are all consistent. For example, if you've used the AV In jack on your TV, make sure
you have used the AV Out jack on your video source.
• Try making sure you have connected to the correct jacks.
For example, if you use the Component jacks, labeled Pb, Pr, and Y, to connect your TV and video
source, make sure you have connected the blue Pb jack on the video source to the blue Pb jack on the
TV, the red Pr jack on the source to the red Pr jack on the TV.
If you find that the colors on your Samsung TV are correct but just a little too dark or bright, there are some
settings you should check before calling for a repair.
• Backlight, Contrast, Brightness, Sharpness, Color, Tint and so on.
Go in to "Picture" on user Menu then try adjusting options mentioned above.
If you find that there is a blur or "ghostlike" appearance to the images on your television's screen, you might
be able to correct it by taking advantage of Auto Motion Plus.
• Auto Motion Plus : User Menu → Picture → Picture Options → Auto Motion Plus
If your Samsung TV appears to turn off by itself, there may be an issue with either your Timer settings or
your Eco friendly No Signal Power Off feature.
First make sure you Sleep Timer is not accidentally set. The sleep timer allows you the comfort of falling
asleep with the TV still on but, turns it off after a certain period of time so as not to waste energy.
• Sleep Timer : User Menu → System → Time → Sleep Timer
If the Sleep Timer is not activated, you may have engaged the No Signal Power Off or Auto Power Off
feature.
• No Signal Power Off : User Menu → System → Eco Solution → No Signal Power Off
• Auto Power Off : User Menu → System → Eco Solution → Auto Power Off
Before Turn on check red light on the right or left bottom of your TV. Press power on button on TV
or remote and it will blink about 5 times before turning on.
If you find that you are having trouble powering on your Samsung television, there are a number of things to
check before making a call to the service department.
• If you happen to be using the TV as a monitor and the stand-by light only blinks for a few seconds when
you press the power button, your PC is in sleep mode. To take your PC out of sleep mode, press a key
on your keyboard or move the mouse. Then try turning your TV on.
If you're sure your power cord, remote control, and PC are functioning properly, you may be having a cable
issue. If you have a cable or satellite box, your TV may appear to be off because the cable or satellite box is
not outputting a signal. To test the signal output of your cable or satellite box, press the guide or info button
on the cable or satellite box remote control. If the screen displays the guide or info data, the problem is
caused by the box.
If you have any trouble to assemble the stand though you refer to "Install the Stand" mentioned at this
manual, visit www.samsung.com/spsn then check "2011 Stand Assembly" on "Top 7 TV Troubleshooting
Tips".
Re-run plug and play. See page 10 for detail
