RE: Got a HP 19C
Thank you for the sugestions.
Did I say it did not look like an absolute disaster? Well, it turns out it is. Just opened the calculator, to find four broken Ā«golden fingersĀ» ( it was not me, belive me). Plus some white stuff on the coil at the bottom of the PCB and blue stuff in the nearby big resistor.

edit:

broken fingers can be seen on the left
I think blue dirt comes in fact from damaged capacitor (in green)
From what I have learnt reading around here, I expected to have to do some cleaning and replace some faulty capacitors.
But.... removing the PCB is more chalenging than I thought, so for the time being I will left the machine as it is. Do not want to scratch or break something.

Actually, putting the two halves of the machine back together is tricky, but easier than I thought. The trick is to align carefully the bottom edge of the machine, and then snap it close.
