HP41-CV Troubleshooting

[hoit]

Hi Diego,

many thanks for the response. I guess people would get tired of answering the same noob questions. It would really help if there was a "sticky thread" that had basic troubleshooting tips.

In the end I cracked open the calculator and found the processor had some corrosion on it. I cleaned it as carefully as I could with isopropyl but could see some of the tracks looked to be in poor condition.

I sourced a replacement processor from a helpful seller on eBay which has fixed my problem.

Cheers
Hoit
