Specs? Model? It's quite easy, but it helps to know what we're working with... What's the video chipset? SiS, Nvidia, ATI, Intel?
As for cables, it all depends on your TV. Most laptops have an SVHS output. If your TV has this form of input, you just need that cable. If not, you need an S-VIDEO to RCA converter. You probably would want to invest in a headphone(3.5mm) to RCA converter or cable for audio.
