Disc Slot Issue

Whenever I put a game in, it gets stuck and i have to slap my Wii (hitting it doesn't work for some reason) to get it back. Is there ANY way to fix this without sending it into Nintendo?

Did someone try to jam a disc in it while there was already one in the Wii?

No, just, one day, it stopped working like normal. I'm not sure what happened to be totally honest.

It sounds to me like the pins on the drive have been bent inwards. Usually only happens when a disc is in and another one is being forced in. Send it out for repair, or if you feel comfortable, open it up and bend the pins back. Or the eject motor is sticking.
