RE: Bad HP41 display? Shows @'s and whistles
Struggling the same fight these days.
Have a CV that sometimes turns on all ?, sometimes nothing or invisible, sometimes only 6 or 7 ,-signs, sometimes only all annunciators, sometimes only left half or only right half of the display showing something, most often waste. Found a loose display contact cause it was singing in the top but the buzzer. Resoldered. Now the buzzer is wheening displays same waste as before. It the chewing gum zebra. So you don't know it does good contact or not. Can't measure after you close it for testing. Is there a source for golden zebra replacements or substitute for reasonable prices? Or solder all contacts from keyboard to mainboard as I have seen somewhere (Monte and the 41CL?) I live in Europe. Andi |
