After the mess, ...
... it was time to reorganize a cool place to continue this restoration :-)
Without the schematics of the two power supplies, I decided to follow
the tracks on the printed circuits boards from the area where I measured
the collapsed regulated 5vdc, I start to check the components and try to
understand the problem alone, I decided to check the 5 big capacitors
this one is a little bit high but OK
YES ! I finally found a dead one, hourra!! :-)
A 23000µf 15VDC used in the filtering of the regulated 5vdc, but...
finally no, unfortunately ... it was not the source of the power fail :-/
Tomorrow I continue my investigation and I will check the big capacitors
of the other power supply in charge of the 15V which is monitored and
possibly also the cause of the error message.
