When I try to connect my pc to my tv it starts to play then quits. i have a samsung lcd hdtv. I tried connecting with my hdmi cable.

Does the screen go black, yet the computer itself keeps running? If so, you'll have to enable the second display. Typically you do this via fn+f5 or through the display options.
