That is the blink code for the lamp ballast. Here is the more complicated explanation from the service manual.
IC2301(pin11) detects the error of LCD Power C.B.A. and Lamp,
then indicates the error when an inner malfunction of LCD Power
C.B.A. occurs, the Lamp voltage becomes more than 130V or
less than 30V, Lamp current becomes more than 5A, or the Lamp is blown
Hope this helps.

Circuit board inside is bad. You need the "SC" board replaced. This is the most common board causing the shut down with 7 blink condition. there is a firmware upgrade that needs to be done to the TV after the board is replaced to prevent this problem from happening again. Contact an authorized Panasonic repair center, they will know all about this problem. if you find a "consierge Service center" you can get two day service on this set. Must still be under warranty? this is a new model.
