Describe the problems.
Are they broken displays, or is the problem less dramatic?
The only real hope if the display is broken is to get another good display from an otherwise broken calculator.

display is not cracked at all. The first, third, and forth digits have missing LCD segments on the numerals.
Is it possible to purchase a new display or the only 'part factory' is an existing model? Do I actually have to go to that extent or is there something simpler that should be checked first (loose contact ...)? There is no evidence of battery ooze and no indication of mistreatment.

That sounds like a couple of bad connections to the LCD display.
However I have never dissasembled an HP41 to the extent that Itried to get at those contacts.
The last time I did that to anything with an LCD display, it never worked again. I have learned my lesson :-)
There may be others who learned in a different school though.
