I bought a white Wii U from walmart, hooked it up, went through the setup, and left it update while I went out. Now, when I turn it on, it powers on like it's gonna boot up normally, then the signal cuts out for a second and a screen comes up saying there is a disc drive error. I took it apart and checked the connection and it seemed fine. I put a game in and it took it in. When I power it on without a disc, it sounds like it's trying to eject something anyway. Is there anything I can try to fix it?
