In my eyes, the condition is very good, so it will be a lost if I don't get this running again. (what wouldn't you do for an old calculator that was a dream when it was released in the late 70's)

Usually the problem (a false contact) due to one ore more broken posts, it's not so simple to solve
after any repairing (I mean a replacement or a rebuilt of the posts) there is to try quite a lot to adjusting the screw's tightening.
You get this kind of problem (but it's rare) even after a replacement of the board, into a perfect look machine, but this is more simple to solve, finding by attempts the good thghtening: these machines are forty years old... Usually you get, as you described, @@ o strange characters in place of the starting four zeroes or the "MEMORY LOST".


I hope and I'm quite sure the shop will return you a perfectly workig 41, good choice.
All the best

edit: typos

You were right, It returned and all is working perfect. It was something with the processor card that was the problem and it was replaced.

It was sent from Spain yesterday arrived at my home in Sweden today! That's very impressive.
