That is almost always an indication of main-board failure on these Bravia LCD's. Unfortunately this is a very difficult repair, and unless you are an
electrician I would not recommend attempting it. You will need to
contact a local TV repair person in your area. If you think it may
still be under warranty please contact the manufacturer to file an
RMA. If you happened to purchase the TV with a major credit card (not
a debit card) there is a good chance it may still be under the free
extended warranty most credit cards place on electronics. Please
contact your credit card company to inquire if they do this, and they
will be able to file the claim and get you a refund for the TV.
Let me know if you want me to try and track down the part for you, but please make sure you think you are capable of doing the repair.

Here is a link to the service manual--
Page 11 explains the error codes--unless you are a tech with a meter etc it will be a shop repair.
A lot of good info including taking set apart correctly.
