I tried to fix my Xbox 360, I found some old games that I wanted to play but my disc tray was stuck and my laser was messed up, to fix it I opened up the Xbox and the disc tray and cleaned the inside of it. After attempting to fix it, I turned on my Xbox and heard a loud grinding noise. I’m not sure if the laser works, as I’m scared to put a disc in it just for it to break or something. What cluld this grinding noise be? It sounds sort of like a chainsaw. And before anyone tells me I should get a new console already, I have a PS4.
