Is the extended desktop showing on your Tv/monitor? if not, your computer graphic card is not detecting your tv. I had the same problem with my Hp laptop, at first it detect my tv/monitor and all of sudden just go black. Would not even flick my tv when I set the extended desktop. Hp have to fixed my graphic card. Try another pogram like winamp and if you have video file you should be able to put the video screen on the TV/Monitor. If same result, your graphic might the culprit.
