So i recently got the old version of Xbox 360 from my cousin and i am trying to hook it up using HD/AV component wire. I am trying to run it on HDTV, my TV supports it. It is working fine on normal TV mode but when i switch it to HDTV and switch the Yellow wire with the Green one, the video won't show up. My tv says NO INPUT. I bought another component wire but still the same problem. I can hear the audio just fine but there is no Video signal. Help please.
