Ivo,
I experienced a tantalum shorten on the CPU board, they were unusual
non-polarized three terminals tantalum caps.
I changed it following the suggestion of a friend of mine who repaired
a lot of them having the the same problem of your.

Have a great day.

Hello Massimo.

I will have a look.
It is a strange thing though; normally, when you pull out the units
one-by-one, you easily can find the one with shortened decoupling
capacitors. With this error i can pullout any unit I like; still the
SPMS stays in this non-boot hickup mode! I cannot figure out what is
going out here.........that's why a schematic could help....
