These blinks [flashes] are fault indication (Error Codes). From the number of blinks occur at one time switch ON, you can get an idea about the faulty circuit section inside it. This will make repair easy. These are called blinking codes. Make sure about the exact number of blinking of the standby/power LED, by switching On & OFF the set, for at least two times. Count it carefully. If you wish to get some details, check the site linked here. It has details about blinking codes, and fault locating procedure, to many popular brand TVs and other devices. http://electronicshelponline.blogspot.com/

In all the time that you have had the tv have you applied 2 firmware updates that some of the tv's need to avoid other known issues with the lcd in the future. These firmware updates are for the main cpu PH1UU112 and the monitor MD1UA104. I don't know if this is the case for you but it worked for me. Call Sharp at 1-800-237-4277.

Sounds like your screen is broken or has been impacted. Force the television on by doing this: Unplug it and on the side of the television where the panel buttons are hold down the ch- and vol+ buttons. Then plug in the television while still holding them down. The television should come on and you see the cracks. Unfortunately it can't be repaired.
If it isn't ch- and vol + then try ch + and vol -.
