   • If no lines are visible on the menu screen after power reset, other external sources (such as cable or satellite box, internet video device, or other devices like a DVD player) or cable connections could be the cause of the issue. Check the following to try to resolve the issue:
     • Turn off any electrical or battery-operated devices that may create radio frequency (RF) interference.
     • Adjust the antenna direction and location.
       • Nearby mountain or tall buildings that reflect the broadcast signals may cause ghosting in the picture.
     • Check if the cable is firmly connected to the TV and the connected device and make sure it is not loose.
     • Use a spare cable to replace the currently used one and see if the situation will improve.
     • Use another input terminal of the TV.
       1. Connect your device to other input terminals of your TV.
