RE: Seeking repair recommendation for HP 67
1) Probably the led is dead.
- Try first to clean the led contacts.
- If it does not work, find a compatible spare one (in sets of four digits, I believe) from a compatible donor (better non working models: all "classics"...if working, I recommend to sacrifice the HP45...it is the cheapest and less painful...well, it is always painful)

2) Will depend if the card reader tracking roll has been already replaced, if not, do it…(lots of tutorials here and there)
- if yes, it is usually a matter of mechanical calibration (contacts, excentric axis of the tracking roll), always check the contacts...
- if none works, then go to the less usual issues (this does not mean impossible to happen ;-D): electronic components failure (mainly capacitors...google in this forum, I am not familiar with this issue).


3) It does worth a lot to get this unit repaired!!!!


4) thecalculatorstore.com , based in Barcelona, offers this sort of services, occasionally...I myself do collaborate with José González.


Regards

Ignacio


Good luck
