Yes ! I found it !

You are right, there was indeed a beginning of corrosion with a leaking
battery. I had taken it away, I could not remember it at all.
I still have to find the voltage of this missing battery, do you know
it? Otherwise I have this UTS20D, there may also be a battery with the
same value ...
So I cleaned the rest of the acid, no damage I think.

So it would only be the cause of the blank screen? That would be so
great !! :-)
I also disassembled the PSU board, some inflated capacitors, I'm going
to replace all these caps. There is also a broken/burned "molex" connector.
I will repair all this and I will post a topic dedicated to the
restoration of this machine.
Thank you all for the information !

Can you tell me where the batteries are supposed to be, on which board?
I disassembled the machine, extracted the 4 motherboards, I did not
see any batteries anywhere.
If they are externalized, maybe I removed them a long time ago in the
idea of replacing them, but I have not yet found where they were
connected in that case.

I do hope you get it going. If you feel qualified, one thing I'd
also look for are packs with batteries to hold information that may
have decayed. That sometimes can cause what you described. since
the system may have been left since 1999, the batteries may have gone
onto corrosion and you may have a bit of fixing to do for that.
