If the power indicator at the bottom of your TV is on but there is no picture or sound, the set-top box may be turned off, the wrong input may be selected, or the HDMI cable may not be securely connected.
To troubleshoot the issue, first press the Volume button on your TV remote and check whether the volume level appears on the screen.
Then restart the set-top box. Disconnect the HDMI cable, and then reconnect it securely.
Why Your TV Has No Picture or Sound
- The TV may be on while the set-top box is turned off.
- The selected TV input may not match the HDMI port connected to your set-top box.
- The HDMI cable may not be securely connected, preventing video and audio signals from reaching the TV.
- The TV may have an internal issue.
How to Fix No Picture or Sound on Your TV
Step 1. Check Whether the Volume Level Appears on the Screen
- Press the Volume button on your TV remote.
- If the volume level appears on the screen, your TV is working properly and there may be an issue with the incoming signal.
- If nothing appears on the screen, unplug your TV. Wait one minute, and then plug it back in. If the issue continues, your TV may need service.
Step 2. Turn On and Restart Your Set-Top Box
- Turn on your set-top box using its remote control. If the issue continues, disconnect the power cable from the back of the set-top box.
- Wait five seconds, and then reconnect it to restart the set-top box.
Step 3. Select the Correct TV Input
- Press the Input button on your TV remote. If your remote does not have an Input button, press and hold the Home Hub button.
- Find and select the HDMI port connected to your set-top box or external device.
Step 4. Reconnect the HDMI Cable or Try Another Port
- Disconnect the HDMI cable from the TV and set-top box. Reconnect it securely to both.
