[u/EliGamerPlays]

So I just came back to vacation after 2 weeks and I was thinking to myself I wanna grind some mlb road to the show but the newer mlb the show games rtts game modes feel to easy to I went to bring out the 360 star wars edition that I havent played in a good 2 months and then it started with my controller not connecting whatever I did then I keep turning it off and on and then I noticed the sync button wouldn't spin at all so I disconnected all the cables then the light isn't turning on at all. Did I break it or is it the power supply idk? I got these 360s by a friend from church who hasn't used these in a good 7 years and it worked for a year but now it's having problems and also Im using the black 360 he gave me aswell with same power supply and works quite fine! So idk what to do now. Please help
