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.

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.
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 (G/R) 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.
