Thanks to all for support.
I have tested the PSU again, the 5 volt is ok (5.68) the 12 v is weak (11.68) and -12 v is really bad (-8.69 if i remember clearly)so if you are right genie-mac i have got a problem here.
Some pictures:


On the down side, i just discovered yesterday that something else was missing from the Logic board :

(the board was washed yesterday BTW)

The Video ROM is missing as well !! so will probably be looking locally for both items(a relative has a spare SE/30...so hopefully will be able to get it)
