You my friend are experiencing an 'Optical Block' failure. Google 'Sony optical block google' and you will find a wealth of information relating to this particular occurence. Myself and many others in Australia and around the world are having quite a bit of difficulty in having Sony rectify this problem. I wish you luck in what will become a lengthy endeavour!
We have a page on Facebook now that can give you all kinds of advice on this issue. We are now suing Sony and winning. When they tell you that is their "Final Offer" it is time for you to tell Sony that you have a final offer for them.
