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.
