problem Amiko Alien 2 and HDMU

sorry for the english but I'm Italian!
I tried to install it tells me HDMU-component-hdmi scart any of these I get stuck after I select 50hz when it comes out! What can I do? if I try to start spark will not start on the display of the receiver I get -----------
the procedure I have made is the following:
insert the key into the folder with the image enigma2 in the back door of the decoder
holding ok turn the decoder
I'm going to enigmatic and hit ok
turn off and power back kept ok
I'm going to enig key v + begins to load
and I find myself stuck with the 5ohz on display

excuse the ignorance as you can see views that the screen remains black and the decoder remains the word boot?
