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.

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

deliver HD (high definition) picture quality.

• A weak signal can cause picture distortion. This is not a TV problem.
• Mobile phones used close to the TV (within 3.3ft) may cause noise in the picture on analog and digital channels.

Incorrect or loose connections may cause color problems or a blank screen.
