HP-41C malfunction during startup

[prwktokali]

Thanks for the warning damaltor! Either way i have to find a magnetic card in order to use the reader, which i haven't yet.

As for the repair, after opening up and tinkering with the cpu connector a few times i finally managed to get the calculator to power up without issues. The new issue that came up is that the display will now turn off by itself after 15-20 seconds of inactivity, which is not a huge problem thanks to the constant memory. Just press on and continue from where you left off. I found a post regarding the same problem and offering possible solutions but i am hesitant to open up the calculator again since i can already feel the screw posts getting weaker and i am afraid that the repairs are not gonna last for long.
I suppose my next step is to learn how to set the constant ON flag, but until then there's lots of reading that needs to be done.
I'd like to thank you all for your help and for maintaining this community. Hope that as time goes by i will get to be an HP expert myself and help others in return
