Screen flashes, then Blinking red light

Hi, i have a Panasonic TX-L50B6B which stopped working today while watching something. I turn the TV on, the green light flashes quickly like normal but when the screen comes on it pops up for a split second (flashing 4-5times) then goes back off, does this for about 5 times then the screen goes off, left with a blinking red like for about 5 minutes. It will blink once, wait about 2 seconds then blink once again. Any help would be much appreciated! Thank You!
