Hi everybody,
I have received a second HP41C unit, and I did some repair on it.
One of the internal battery contacts was ruined and I have restored it with a thin metalic film soldered over the original contact.
It worked out, since now the unit is turning on.
However, the display is not able to light up all the segments, making it unreadble and unusable.
I have warmed and re-soldered the display contacts, both on the keyboard side and on the display back, but nothing.
For example the ALPHA label is not showing up on the display, even if the unit is in alpha mode.
What could I check without destroying the machine ?
Thanks for help, take care Alberto
