Yes, it is a bad optical block. Sony released a recall on most A2000 models, and all A2020 Series Television sets, and settled a class action lawsuit. I had a buddy get an optical block replaced in 2010 under the suit, but the extention window expired August 2010. You could possibly contact sony, and see if there's anything they're willing to do, but legally, they're exempt from responsibility.https://sites.google.com/site/sonylcdrptvproblems/sony-class-action-lawsuits
They are absolutely incredible TVs.
