I have a Sony HD Smart TV was only about 8-9 months old when I replaced it last year. It was the victim of a power surge and will no longer power up. I believe it is repairable, but not many people do this repair. I spoke with one repair guy and said it probably needs a new board and power supply. He quoted around $500 to fix, but said his work table was too small to handle the large size. It is free to any one that can fix it or know some one that can.
