my BDP3000 can no longer read DVDs or CDs. It tries to load them, makes tic-tic and writes "No disc". Blurays were still good yesterday, but are now refused. Player makes tic-tic-tic then writes "UNKNOWN".

Is there a way to clean the lenses or something before throwing it outside the window?
I'm a bit disappointing with this product, it's not even 2 year-old.
