RE: HP 41 not working
Today fiddled around with a 5V DC power source in the calc.
When I put power only little life appeared in the display for a very short time.
When power switched off the display shows some signs of life.
Switching on and off more often and fast changes from upper half of starburst in the right half of the display to full width of the display's upper half starburst.
Waiting with no power for about 5 seconds I can repeat from the start with only little signs of life.
Any ideas?
Thanks
Andi
