Ok. Done some more tests.
The green led (the only one that turns on) do not flicker, it remains steady.
I tried 3 other Kickstart sets and nothing changes. :(
The behaviour is always the same (black screen and steady green led).
Somewhere I also have a set of 3.1 Kickstart set but I cannot remember were... I am going to look for it in the next days.
Anyway I do not think that ALL the 3 3.0 kickstart sets have died in these not usage years! :(
I have also tried without the Kickstart chips and the behaviour is the same with or without them, so the issue should be (according to what I have read) that the Amiga cannot pass the control to Kickstart... :( :( :( am I right?
I am quite sad. I am afraid that the possibility to repair the mobo is beyond my capabilities... I am not capable of testing electrical parts understanding what's happening or desoldering and soldering chips... :( :( :(

One more thing: I removed the FDD so all my tests have been done without it, but I do not think it can change the situation (obiously the first tests were done WITH the FDD connected!).

 Sure you have loads of amigas and a1200's, it's not the end of the world if it doesn't work anymore ;) first world problems..
