HP 41C Switching On Problem
I have 41C. Since last few days it does not switch on. It means it does switch on some time. The batteries have total voltage of 6 VDC.

Have a look on the flat-flex connector on the main bord. These connector is only pressed (with the four vises under the rubber pad). Often corrosion appear on this flatflex and disturb the HP41.
So let me know waths up ,
have a look on this :
