I recommend the parts of http://www.thecalculatorstore.com

There are smart solutions for zebra connectors and many others. The new zebra design is incredibly simple and works very well.

For the back cover + IO connector problem, you will find a combined solution by sticking the IO connector to the back cover, this makes it stronger and avoids the weakness of screw areas. Also indenpendent solutions are available either for the screw areas or for the IO connector.

Reliable solutions for upper and lower posts, which are really the weakest design point of HP41 series.

I can say that, except for the display, you can find good solutions for any HP41 series at http://www.thecalculatorstore.com and at a reasonable price. I am not commercially linked to this portal, to avoid suspicions.

Kind regards

Thanks a lot Ignacio.

Not sure I understood about the combined solution of the back cover + IO. Can u clarify ?

I knew about the site and maybe I'll buy something, but first I want to understand if it's a contact problem and maybe just fixing all together correctly will make it restart working :-)
