Keys on HP-41 CV intermittently stop working



#3

The central keys (. 2 5 8 CHS STO SIN SQRT) of my beloved HP 41 CV stop working for time to time.

Does anyone has an idea how to fix it ? or know a repair centre or someone who can do this in Europe ?

Thanks for your replies !


#4

I had the same problem with my 41CX a time ago. Then I decided to open it and take a look inside. Nothing looks bad and did some cleaning with compressed air and everything worked fine again (maybe some dirty).
