Part 1 of my HP41CV repair report.
Disassembly
After removing the 4 rubber feet 4 screws were loosened, the back cover lifted. and coveres removed:
Looking into the void between the upper and lower PCB it became obvious, that there only was partial contact between them by the flexible contact rolls (no image of that, hard to take a picture, sorry), so I removed the the upper PCB and the flexible connection roll(s):
This gives access to all connection pads and also (sadly) obviated that the lower right fastening pole is badly broken (i.e. horizontally and that broken off part broke into two pieces a few moments later).
Contacts cleansing
Staying cool about that broken pole I've now first proceeded by cleaning all contactpoints with a mild nail lacqer solvent (had good experience with that in other gold on gold contact problem cases).
This is where I stand now. Next step is the repair of the mounting pole and then reassembly of the unit to see if we have progress or success already.
What I actually have at hand is an "Ethyl-2-Cyanacrylat" glue which I hope will do the job as it helped well in other plastic glueing cases which needed to provide mechanical stability... Any more hint, warning and/or advice would be much appreciated!
Kind greetings,
