TV and streaming

My TV says no signal. How do I fix it?

No signal usually means the TV is looking at the wrong input, not that the TV is broken. The cable box, Roku, Fire TV, or HDMI cable may be on a different input.

The short answer

Press Input or Source on the remote, try the HDMI inputs one by one, and make sure the cable box or streaming device is powered on.

Try these first

1Check whether the cable box, Roku, or streaming device has a power light.
2Look at which HDMI port the cable is plugged into.
3Try Input, Source, or Home on the TV remote.
