Since I got my Xbox it hadn’t turned on. Then I decided to take it apart. I disconnected the dvd drive cable from the motherboard, ad then it turned on. I connected it again and it will not turn on again. I hope that someone can help me with this problem.
Why exactly did you disconnect the disk drive??????? That has nothing to do with power?????? Anyways, check if the power brick is plugged in. Both wall outlet and console.
