Re: HP 41CV freezes on pressing ALPHA Message #3 Posted by Martin Sonntag on 26 Sept 2007, 6:26 a.m., in response to message #2 by Karl Schneider
Karl,
yes, it's a fullnut, so not all hope is lost :-)
Examining the PCB closely, I found a few tiny metal chips
stuck to some of the contacts. A good cleaning is obviously necessary.
I'll try to get hold of an ultrasonic cleaner, then.
Are there any joints which I should have a closer look at (i.e. known weaknesses of this machine)?
Martin
