- check your display settings: the output should be set to dual/clone to send a signal out the svhs-plug

 

- if the tv-out option does not appear, check the svhs-cable. it might be bad or damaged. happens quickly. if the is the case, the tv-out option will not even be available (as if no cable was plugged in)

 

- once you're sure the screen clones, check the tv-out format (ntsc or pal, whichever applies)

 

- last: if you want to play video, make sure tv-out is set as primary output. otherwise, you'd have the video overlay on you laptop screen and the same spot on your tv will remain black.

 

hope this helps.
