My blu ray player isn't working?

My blu-ray player all of a sudden stopped working. It says "cannot read disk"?

• Whether or not I put in a dvd or a blu ray it says- cannot read disk. Now, just last week all of these discs worked. Nothing has happened to the player (dropped, hit, etc), it just out of the blue decided not to do anything anymore. Player is not even a year old yet. It has had firmware updates in the past so it's not a firmware problem. Plus, all of the discs I'm trying to get it to read are older ones that played before, thus it is not a firmware problem.

• Answer:

  Clean it. Use something like this: http://www.amazon.com/Maxell-BR-GAME-Blu-ray-Game-Cleaner/dp/B0029HLO4S/ref=sr_1_2?s=electronics&ie=UTF8&qid=1298054059&sr=1-2
