So yesterday my Xbox 360s stopped reading any discs, CD, DVD, or game. For the past 3-4 weeks it started giving an Unrecognizable Disc sign which would later be self-resolved and I would be able to play any games. I'm assuming this is a laser problem. Furthermore, I am often having trouble signing into Xbox Live even when my connection is absolutely fine. It does work eventually but it takes some work. Also, occasionally, the disc will be recognized but it will then proceed to give a Disc Unreadable error. Any suggestions/ solutions?
PS: It will play downloadable games that I purchased from the market place (ie. Minecraft, CoD: BO).
