Weak or No Signal / No picture or sound — Input issue or channel problem

What does Weak or No Signal mean?

The TV is displaying a 'Weak or No Signal' message, or there is no picture, video, or sound, or it appears distorted when connected to an external device. This can also happen when trying to find TV channels.

• Incorrect or loose cable connections to external devices
• Wrong input source selected on the TV
• Faulty connection cables
• Problem with the connected external device (e.g., cable box, DVD player)
• No TV channels tuned via antenna or cable wall connector

Click steps to track your progress.

1. 1

   Ensure all cables connecting to the external device are correct and fully inserted into the TV and the device.

2. 2

   Remove and reconnect all cables. If possible, try using new cables.

3. 3

   Confirm that the correct input source has been selected using the TV's Source menu.

4. 4

   Perform a TV self-diagnosis (Picture Test or Sound Test) via the Support menu to check if the TV or the external device is causing the problem.

5. 5

   If you are using an antenna or a cable wall connector (without a cable/satellite box), run Auto Program to search for channels.
