Hey everyone, I just recently have taken my old Xbox 360 out of storage and in an effort to play it again. I hooked up everything correctly but when I plugged the power brick into the console and my wall outlet the brick was lit yellow. After I pressed the power button on the Xbox the power brick turned to a red color. I unplugged the brick from the system and the wall outlet for it to cool for about an hour. However, after I plugged the brick back into the system and the wall outlet the same problem happened. I'm assuming the power brick is simply old and needs to be replaced but it may also be something with the hardware in the system. Any suggestions? Thanks!
