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.

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.
