I am having a 6200 256 mb winfast graphic card. I wanted to connect my TV to the PC. I had got a cable along with the graphiccard which looks like this :

I tried connecting my computer to the tv by connecting a component video cable to the nvedia cable (the green and blue cable) . It worked , but i could see the screen only till windows loaded (ie, everything became blank in the TV after the windows boot screen). Same thing happened even for ubuntu. Can anyone please tell why is this happening?
