Hi Thanks to info in this forum. I have fixed my problem with my less than 1 year old Panasonic Viera LED TV. It has the red light flashing problem. Turn it off and on will display stuff on screen for a brief moment and then it turns off with the red light flashing every few seconds. The fix for me is holding the on/off button for a good 10 seconds or so as suggested and voila it works. Hope this helps.
