Where Should I Get My Ps3 Fixed or How to Fix a Ps3?

a little while ago i knocked over my ps3. when i tried it again it started up normal and it works fine but it won't let me insert a disc it will eject them. if anyone knows of a good place to get it fixed can you tell me what there website is. i also know someone that fixes computers if anyone could explain how to fix it that would be best so i could save money.

Suggestion:

call sony
1-800-345-7669
they fix them , it might be under warranty still
