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 !
