My suggestion( Alternative )
Unplug your box for 20 sec. Press and hold stanby button when plugging it back in. As soon as the light flashes let go and press the up, down, left, right arrow buttons in sequence. Make sure you do it 3 times. The amber light will comeon and the green light will start flashing.. leave for approx 60 sec. Your box should turn on and be back to normal. You might loose your save recordings. Good luck!!!
