Possible Solution

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. Using your remote, follow the steps below to turn these features off or

on.

y Energy Saving :

→ Setup → Eco Solution → Energy Saving

y Eco Sensor :

→ Setup → 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 test

on the TV to make sure there are no device issues.

y Self Diagnosis :

→ Support → Self Diagnosis → Picture Test

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, etc.

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 (G/R) and so on. Go to "Picture" on the User Menu, and then

try adjusting these options.

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 your Sleep Timer is not accidentally set. The Sleep Time 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.

y Sleep Timer :

→ 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 :

y Auto Power Off :

→ Setup → Eco Solution → Auto Power Off

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 before

making a call to the service department.

y 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 assembling the stand, refer to "Install the Stand" in the Start Up or Stand Installation Guide.

Re-run plug and play.

First, perform the Picture Test and to see if your TV is properly displaying the test image.

Go to

- Support - Self Diagnosis - Picture Test

If the test image is properly displayed, the poor picture may be caused by the source or signal.

If you have an analog cable/satellite box, upgrade to a digital set top box. Use HDMI or Component cables to deliver HD (high

deﬁnition) picture quality.

Cable/Satellite subscribers: Try HD channels from the channel line up.

Air/Cable Antenna connection: Try HD channels after running Auto program.

✎

Many HD channels broadcast SD contents upscaled to HD. The picture quality of upscaled SD content is low.

y Adjust the Cable/Set top box video output resolution to 1080i or 720p.

y Compression of video contents may cause picture distortion, especially on fast moving pictures such as pictures from

sports and action movies.

y A weak signal can cause picture distortion. This is not a TV problem.

y Mobile phones used close to the TV (within 3.3ft) may cause noise in the picture on analog and digital channels.

If you're using a component connection, make sure the component cables are connected to the correct jacks. Incorrect or

loose connections may cause color problems or a blank screen.

y Adjust the Picture options in the TV menu. (Go to Picture Mode / Color / Brightness / Sharpness)

y Adjust the Energy Saving option in the TV menu. (Go to

y Try resetting the picture to view the default picture setting. (Go to

y If the picture size is set to Screen Fit, change it to 16:9.

y Change the cable/satellite box resolution.

y If you are using an AV composite input, connect the video cable (yellow) to the Green jack of Component input 1 on the

TV.

y If the TV is connected to a cable box, reset the cable box. (Disconnect and then reconnect the box's AC cord and wait until

the cable box reboots. It may take up to 20 minutes.)

y Set the output resolution of the cable box to 1080i or 720p.
