HP-19C Repair Odysee

[Artur - Brasil]

Many thanks for your kindly reply!

I will let it in trace, as it is easier. The calculator, in ON mode, and having all parts (except keyboard front part) attached moves the head printer to right position, but none on display. As you did, I changed the two transistors in power circuit and this restored voltage levels but nothing on display. I tested the display with a multimeter and LED segments are working.

It's sad to see a beautifull machine stoped like this one.

Best regards,
Artur!
