First we need to know which one of the 9 different models of MacBook you have. To see which model you have go to the Apple in the upper left corner and select About This Mac, then click on More Info. When System Profiler comes up check the Model Identifier and post it back here.
The Late 2008 model 5,1 Aluminum Unibody and the Late 2009 model 6,1 and Mid 2010 model 7,1 White Unibody have a Mini DisplayPort.
The Early 2006 model 1,1 through Early 2008 model 4,1s plus the Early and Mid 2009 model 5,2s have Mini-DVI ports. Each would take a different adapter to connect with the TV.
Depends on what input plug you'll be using on your TV. VGA, DVI, Composite or HDMI. You'll need a Mini-DVI adapter and a cable from that to your TV. Here's the various types of Mini-DVI adapters on Amazon.com http://www.amazon.com/s/ref=nb_sb_noss?url=search-alias%3Daps&field-keywords=min i-dvi&x=9&y=13
(Composite is the red, white and yellow RCA plugs on your TV or red, white and S-Video plugs.)
You'll also need audio cables to the TV if you use VGA, DVI, or Composite using a 3.5mm stereo headphone jack to RCA sound plugs or a 3.5mm stereo input plug for audio. You attach it from the headphone jack of your MacBook to the appropriate audio input plugs on your TV.
If you connect the MacBook using a Mini-DVI to HDMI adapter you will probably need to use external speakers or a 3.5mm stereo headphone jack to RCA sound plugs connected to a stereo system for audio if your TV doesn't have separate RCA input plugs or a 3.5mm stereo input plug for audio with the HDMI plug. You attach it from the headphone jack of your MacBook to the appropriate audio input plugs.
The Mini-DVI to HDMI doesn't carry audio and there're no audio plugs on most TVs to work with HDMI since it's expecting audio with the HDMI. Check your TV manual though to see if it might have audio plugs that work with one of the HDMI ports. You attach it from the headphone jack of your MacBook to the appropriate audio input plugs on your TV.
