Ok the boards of my friend are here.
There are RGB input and driver boards. Horizontal, SMPS and G2 board.
I tried to swap all but no fix the issue.
So I think that the issue is the controller.

Does this blue image change at all or is it this steady. And if it is steady, does it do anything, like flicker jump or anything at all if you hit any buttons like menu, input or any others?  |

Why don't you try with your friend's controller ? I am willing to send you my working spare controller, just to see if yours is faulty. But i thing you'll find someone closer to you, there in Italy for that.

My friend have two other working 909's but he isn't so expert to pull fixed boards. |

Well are you ready to fire up your soldering iron and get to work? Yes but I don't have any idea about how find the failed point. I inspected the surface of the controller but don't see any component superficially damaged. |

Well first thing I would like you to try is to disconnect the 3 video output wires on the input board and turn on the projector. I want to see if the video disappears. Should be the white wires on J250, J350 and J450.

Ok the white wires are disconnected. The projector show same reaction that described in previous posts.

Exactly: the blue turn bright with noise then too low. The red and green always low.
