Panasonic Tv Red Light Flashing 7 Times. Replacing it would be over a $1000 which is just not an option. A common cause of death is the 7 blink failure.

The reason why your lg tv flashes with a red light 3 times before turning off is because of an electrical fault with the power board. The 7 flashing lights can mean either a dead/damaged sc board or a dead/damaged su/sd board. First, (assuming the tv is off) unplug the power cable.
