Facing TV Problems? Ask a TV Technician.
Hello and thank you for your question. I look forward to assisting you today. Has anything changed on the cable box?
If nothing has changed other than the settings on the TV, then follow these instructions. Press the MENU button to display the menu. Press the UP/DOWN buttons to select channel and then press the ENTER button. Repeatedly press the UP/DOWN buttons to cycle through the input choices and select Cable,then press the ENTER button.
Can you access your menu as I instructed?
How do you have the cable box connected to the TV?
