If the TV seems to have a problem, first review this list of possible problems and solutions. 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.
	yy Energy saving : Menu → Setup → Eco Solution → Energy Saving →Select Settings
	yy Eco Sensor : Menu → Setup → Eco Solution → Eco Sensor →Select Settings
Component Connections /	If you find that the color on your Samsung television’s screen is not correct or black and white, first run a Self
Screen Color	Diagnosis Test on the TV to make sure there are no device issues.
	yy Self Diagnosis : User Menu → Support → Self Diagnosis → Picture Test
	yy If the test is ok, try making sure ;
	yy 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.
	yy 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.
	yy 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.
	yy 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.
	yy No Signal Power Off : User Menu → Setup → Eco Solution → No Signal Power
	yy Auto Power Off : User Menu → Setup → Eco Solution → Auto Power Off
Trouble Powering On	Before you turn the TV on, find the red light on the right or left bottom of your TV. Press the power on button
	on the TV or remote and the light should blink about 5 times before the TV turns on.
	If you find that you are having trouble powering on your Samsung television, there are a number of things to check it
	before making a call to the service department.
	yy 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.
