Check if your tv has other connection like ps3 or other hdmi connected devices. If so.. we had the same problem.. the tv blinks and it wont turn on. Tried unplugging it from the outlet and pressed the power button for 10 seconds, but still the tv wont turn on. Then i tried to open the playstation which is connected to the hdmi port 2 and the tv turned on. Our kids shut it the playstation off and did not returned the source to hdmi port 1, thats why our tv didnt turn on and the red light is blinking.. hope this will help..
