[quote name='chodax']This is a dumb question, but how do i know if my TV can use component cables?[/QUOTE]
take a look at the inputs on your tv (this could be on the front or side but is usually in the back)
composite/rca are the "normal" yellow video and red/white audio
s-video will look like you could plug a mouse in there (not a usb, but the old ps/2 inputs on a computer)
component input is red, green and blue colored inputs (all video) and is usually next to white/red for audio
if still confused, you could list your tv make, model, year and someone might know about your specific tv (if it is from the last couple years, it almost definitely will have component inputs)
