Thats a driver error which is usually indicating the SC board has an issue. But it could also be the SU or the SD boards. But the SC is most likely for the 7 blink error

What do 7 blinks indicate?


The Vieras have standby codes that are not published because few Plasma TVs are serviceable by owners. Power surges will cause the blinking sometimes and the only remedy to the owner is to unplug the TV for a few minutes to let the power supply reset and plug it back in to see if you still get the shutdown mode blinks. If you do, the only remedy is to contact Panasonic at 1-877-95VIERA (USA) or 1-866-330-0014(Canada)
