For the Mac Book I think you need to use the Mini DVI to video adapter (store.apple.com) and then connect either an s-video cable (or yellow video out chord) to your tv. If you want to also connect audio you'll probably need something like a stereo to RCA cable (radioshack.com). My G4 Powerbook has built in s-video output, so I usually just connect an s-video cable to the tv and a splitter similar to the one above plugged into the headphone jack. The System Prefs make the whole thing pretty simple really. Good luck! :]

Do what AWA said - pull absolutely everything that can be pulled so your initial troubleshooting is Motherboard and Powersupply only, pretty much. You need to disconnect your hard drive power, CD Rom power, etc.
