HP48S strange behavior

[Daniel Sole]

Hi there, I think I must share my experience in an order others can know. I did the wash and dry process and, after assembling the calculator, I have found out that it has stopped to work.

My opinion is that I twisted too much the bottom part to be able to pry the rivets. In one of the attempts I accidentally entered the metallic piece I was using inside the keyboard with fatal result, I think. I don't think the wash&dry process has been the problem.

The truth is I regret having tried the repair. Anyway, calculator wasn't working right before my botched job.

I'll try to find an old calculator, maybe a not working one, and I will try to use the keyboard as a replacement part. I'm quite sure my problem is in there. If I have some kind of future success, I will post it here.

The funny thing is that on the while I've been working with this, I learned what HP did later: the 49G, the 50's, the Prime... I have purchased now a Prime and I'm going over my math!
