Troubleshooting
If the TV seems to have a problem, first review this list of possible problems and solution. If none of these troubleshooting tips apply, visit
samsung.com, then click on Support, or call Samsung customer service at 1-800-SAMSUNG.
Problem Possible Solution
Flickering and Dimming 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. Follow the steps below with your remote to turn these
features off or on.
y Energy saving : Menu → Setup → Eco Solution → Energy Saving →Select Settings
y Eco Sensor : Menu → Setup → Eco Solution → Eco Sensor →Select Settings
Component Connections /
Screen Color
If you find that the color on your Samsung television’s screen is not correct or black and white, first run a Self
Diagnosis Test on the TV to make sure there are no device issues.
y Self Diagnosis : User Menu → Support → Self Diagnosis → Picture Test
y If the test is ok, try making sure ;
y 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.
y 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.
Screen Brightness 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.
y Backlight, Contrast, Brightness, Sharpness, Color, Tint and so on. Go to “Picture” in the Menu, and then try
adjusting these options.
Unwanted Powering off 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 the Sleep Timer is not accidentally set. The Sleep Timer lets you fall asleep with the TV still on
knowing that it will turn off after a certain period of time and not waste energy.
y Sleep Timer : User Menu → Setup → Time → Sleep Timer
If the Sleep Timer is not activated, you may have engaged the No Signal Power Off or Auto Power Off feature.
y No Signal Power Off : User Menu → Setup → Eco Solution → No Signal Power
y Auto Power Off : User Menu → Setup → Eco Solution → Auto Power Off
