If your laptop has a TV Out connector, which might be an RCA connection, as some do, connect an RCA lead to the TV out connection and to a SCART adaptor, a RCA video connection on the adaptor, or a S-Video lead to the SCART adaptor and then plug the adaptor to a SCART socket on your TV, this should then send a signal from your laptop to your TV
Hope this helps
