Verify that the unit is plugged into a working outlet. Press the power button on the unit to verify it is not a remote control issue. If it's the remote:

Pressing the remote control toward the TV should cause an LED or light on the TV front panel to flash. This indicates a code was transmitted. Verify the remote control is in TV mode. If the front panel lamp or LED does not flash, verify the batteries are installed properly and in good condition. Battery corrosion can cause the remote control to not function. The remote control range is 30 feet or less. A bright light behind the remote control can affect the performance of the remote control. A remote control can be tested by pointing it at a digital camera or camera phone; the transmitter will show white on the camera screen if it is transmitting.

Otherwise:

Perhaps an on/off timer or sleep timer is set.
Or remove the electrical plug from the wall outlet and wait a while before inserting it into the wall outlet again.

If the problem persists or if you require further explanation, you'll have to consult Samsung--use the contact information at:
