IFIXIT.COM is one of the better websites we’ve come across for self-repairs on laptops, tablets, phones, etc. and includes parts, repair kits, videos, etc. to repair items yourself.

Caveat: Self-repairs require time and concentration and aren’t for everyone.  Do shop around.  IFIXIT sells replacement parts but they’re expensive compared with other online retailers.  Lastly, don’t do something stupid like electrocuting yourself because you tried to fix your Xbox while it’s still plugged in!
