Solutions and Explanations
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 Sleep Timer is not accidentally set. The Sleep Timer
turns off the TV automatically after a certain period of time has passed.
Sleep Timer: User Menu
If the Sleep Timer is not activated, you may have engaged the No Signal
Power Off or Auto Power Off feature.

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.
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.
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, visit www.samsung.
