Hello, my xbox dvd drive won't power on. I have removed it from the xbox to see if I can fix it myself, but I don't know where to start. Buying a new one is not an option as the dvd drive has a "key" that corresponds to the "key" in the motherboard. Without this key the xbox won't read any disc. My question is how can I, not knowledgeable in this field, fix this dvd drive. Anything will be helpful! I live in Bronx, NY just in case there is some local repair store or person that can help me. Thank You for at least reading this.
