Panasonic 7 to 8 blinking light after SC board disconnect...help

I have a Panasonic Plasma model TC-P55VT30...manufactured in APRIL 2011.

My Plasma went out on me yesterday, 7/22/14, and after unplugging the power cord and re-plugging it gave me the 7 blinking lights of death. So today, I finally had the chance to take off the back panel today and disconnect the SC board. After doing so, I now get 8 blinking lights. I'm reading the service manual and it says this is a SS board issue. I haven't really found a diagnosis and repair guide for the 8 blinking lights. Help if possible.

Thanks.

SOS7 is almost always SC board or SU/SD.
Do you have a digital multimeter available?

No I don't. I just took off the SC board and noticed burnt marks which it was. So I'm guessing its the SC board.

You will have to replace the SC board, it is also a good idea to test SU/SD boards when replacing SC on this model so you may want to get a multimeter to do that...
