Horizontal Lines On Panasonic Tv

I have a Panasonic television, model number CT-27D12DF. It is approximately 14 years old. I recently noticed horizontal lines across the top of the picture. Can you tell me what causes that? Thank you.

Check to be sure you don't have a bad cable (wire) connection, depending on what component you're using to watch TV. If all cables are tight and not damaged, unplug the TV for 10 minutes and see if that solves. As a last resort, go into the menu of your TV and do a factory reset. If the TV screen is cracked, follow the link--but you may see a blank space. If so, scroll past it to the subhead, "Repairing a Broken Flat Screen TV."
