Hi, hoping for some advice please. My Wii has stopped taking in discs. It's like there's something in the way. It's not making any noises or attempts to pull a disc in. Just before it broke though it ejected the previous disc with no problem. I opened it up to see if there was something stuck in it but I can't see anything however a tiny piece of plastic fell out. It's the same semi transparent white plastic as other parts but I can't see where it has come from. Any thoughts? I think it's too old to be under guarantee, although I've opened it now so that's a moot point.... Please help!
