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 !
