Panasonic Viera TH-P65ST50A 3D Plasma TV turning off by itself

“Hi I've got a Panasonic Viera TH-P65ST50A 3D Plasma TV (Built in 2012) which has recently started to shut itself off after 5-10 minutes and goes into standby mode with the red light blinking. I normally turn it off by the power button on the TV and then turn it back on. It sometimes does this another 2 to 3 times before it stays on completely. Can this be fixed?”
