I have a Pt-56hx41pf Panasonic and when I turn it on it trips off with a red light next to the led power button flashing. When I turn it on again it wont come on. If I unplug it the tv would come on to setup then trip off to the flashing light next to the power button. Now its gotten so when I unplug it wont even come on but goes to the flashing red light flashing light and thats all that happens.
