Summary: Unfortunately this appears to be a common issue developing with these Panasonic sets i.e the '7 blinks of death'! Several customers are complaining about it. The problem is caused by one, both, or all of the following boards: SC board, SD board, and SU board.
Summary: I was in the market for a new TV and knew I wanted another Panasonic plasma. I own a TC-P50G25 (50 inch 2010 model) and a TC-P42S60 (42 inch 2013 model). I have never had an issue with Panasonic, and this TV was rated 5 stars. Got a deal on the 65" so I went for it.
