There are two possible problems: 1. You are connecting a 15-pin (on the laptop) to the 9-pin (on the TV) connection. This isn't the video-in connection for the TV. The TV has a DB-15 connection near its DVI input connector. You should be using a 15-pin to 15-pin cable. The DB-9 connector on the TV is a serial port for servicing the TV. 2. You aren't enabling the external video port for the laptop. Try hitting Fn+F5 on the laptop to cycle between the three display modes: laptop only, laptop + TV, TV only. Make sure to wait a few seconds after hitting Fn+F5 to let the displays sync up.
