To troubleshoot why your Smart TV is not displaying the correct content from your cable box,
here are some steps to try:
Check that all of the cables from your cable box are securely connected to the input port of your Smart TV, and that all of the lights on the cable box are on.
Ensure that the TV is connected to the same internet network or home network as the cable box.
Perform a restart of your cable box and Smart TV by unplugging them from the electrical outlet, waiting 30 seconds, and plugging them back in.
Try changing the channel on the cable box or the input source on the TV.
Consult the user manual or contact technical support if the issue persists after trying the above steps.
