Try the following:
1. Select System Preferences from the Apple Menu.
2. Select the Sound icon.
3. Click the Output tab at the top of the window
4. Highlight the option that is not the Internal Speakers.
5. Make sure the Output Volume is not set low and that the Mute checkbox is unchecked.
6. Close the Sound window. (via Red Radio Button, Top/Left of window).
Try it again and see if you get sound this time.
I hope this helps. Regards,

Your tv doesn't supports the resolution the laptop is sending it . To fix that select in the display settings a lower resolution before clicking Apply - use 1280×1024. After that (once the tv is working) you could try to use higher ones.
