HP-65 1333S05093 restoration and display problem

[albertofenini]

Hello Everyone, Happy Christmas Season

we are in the process of restoring this unit, which is peculiar having an Italian back label,
we are wondering in how many languages these have been translated ...

So far so good, the unit has been cleaned and when the weather will improve we will spray the front with TS-80
The card reader has been rebuilt but the clutch is yet to be done
The unit reads and writes correctly so far, but we have done only a couple of read and write operations

However, the display has a faint digit partially lit in the second block of leds, it can be seen in the last picture
I'm figuring a defective block, but any suggestion is, as always, very welcome

As a tip, we have seen in a video where a Nintendo restoration was performed the use of a ice cube molder
to keep all the pieces, and we must say it's quite useful so we wanted to share the idea ...

Take care !!!
