The Sony WEGA LCD projection TV's have a well known optical block issue that doesn't present itself immediately and in most instances not until the warranty has expired. Sony is aware of the problem and will not provide a recall. The cost to replace the optical block is approximately $1,200.00. Since Sony won't provide an honorable repair for the TV, please don't spend your hard earned money on a TV that will be unusable within 24 months like we did.
