I have this older model Sharp TV and it has recently stopped working. This power button is constantly flashing green. I can hold the button down and it turns red. Then I press and hold again and it turns orange and then after about 5 seconds the screen comes on for about 2 seconds and then shuts off and starts to flash again. I can press and hold the power button again and it turns green and the screen comes on again, but only for 2 seconds as well. I don't know if the is any way to fix this problem, but if anyone knows anything it would be awesome.
