Panasonic TX-50AX802B 9 red flashes

My Panasonic TX-50AX802B has just stopped turning on. When i power it on, the Panasonic logo shows, then the screen goes black and flashes red 9 times on a loop. Powering if off at the wall (including disconnection) results in the same thing. Any help would be greatly appreciated. My local service centre has been unable to get a service model for this TV so if anyone has one that would also be greatly appreciated
