Apple TV: TV Input

Depending on how your TV is connected to your cable box, especially if you have a high-definition TV (HDTV), you may need to put your TV on the correct video input in order to watch TV.

If you are not sure what connection you are using, for information about the different cable connections.

If you are using a high-definition TV (HDTV)
If you're not getting a picture, see a blue screen, a black screen, or a snowy screen, make sure your cable box and TV are both turned on. Once they are, check to see that the TV is set to the correct input/source.

Find the input/source button on your TV's remote and press it until you see a picture on your screen. If this does not work, please refer to the instructions that came with your TV or contact your TV's manufacturer for assistance.

Once you've confirmed that your TV is set to the correct input, check to see that all the wiring is tight and plugged in securely.

If you are using a standard-definition TV (SDTV)
If you have a standard-definition TV connected to your cable box with a coaxial cable, make sure that the TV is tuned to Channel 3 or Channel 4. If you are using composite (red, white, yellow) cables or an S-Video cable instead, please refer to the HDTV instructions above to put your TV on the correct input.
