Pretty much every 360 will suffer from that problem at some point - It's called the "Red Ring Of Death". The problem is determined by how many quadrants are lit - If there is 1 or 3, there is a hardware failure. If there is 2, then it has overheated. If there is 4, then it cannot detect a video cable, if I remember correctly. Call Xbox Support (Its number is mentioned in one of the booklets that came with the 360) and tell them what is wrong, they will guide you through what to do.
