Re: HP 32E Display Question Message #2 Posted by Nelson M. Sicuro (Brazil) on 21 Aug 2003, 11:28 p.m., in response to message #1 by Harry (Germany)
I have a HP32E too, and when it arrives (I bought it through eBay) its display was horrible, digits missing, half-digits. I begin the restoration, and I found that my 32E is that version that the chips isn't soldered (as its display). I disassembled it and begin restoration, cleaning the contacts with a soft pencil eraser. When I assembled it again it was working as new!
Look at http://www.hpmuseum.org/tech30.htm
As your 32E is showing the same simptoms as mine I guess that it is the solderless version too.
In less words: bad contacts, a good cleaning will fix it.
But take care, the case is tricky to open, and the chips just jump away when you take the holders off!
Good luck.
Nelson
