Instructions

Difficulty: Easy

Step1

Check the power cord if your TV does not turn on. Plug it in, then press the power button on your TV or on your remote control. Replace the batteries of the remote control if the TV still does not turn on.

Step2

Reset your sleep timer options if your big screen TV turns off unexpectedly. Or, deactivate the wake up timer if it turns on unexpectedly.

Step3

Adjust the picture quality of your TV if you have picture problems, or if you can't get any picture. Select an input source by pressing the input feature on your TV or remote so that a picture appears on the screen. Find the "Picture" menu to adjust brightness, tint or color.

Step4

Choose mono sound if your TV's sound reception is poor, or choose stereo mode if there is no sound. Check your antenna and cable connections, and try a different channel in case there is a problem with the current channel. Make sure that the TV is not set to mute.

Step5

Verify that your TV is aligned with your cable or antenna source if you're having trouble getting more than 13 channels. Set the "TV/Cable" or a similar function on your TV so that you can properly access your cable service.

Step6

Turn off the closed caption feature if you have a black box on your TV screen that you don't want. Depending on your big screen TV model, it may be set to "text" mode. Use your remote or the controls on the TV to turn off closed captioning.
