My HP-34c turns on fine and works ok; however, when I move the right switch to "PRGM" mode, the calculator turns off.
If I then turn the ON swtich to OFF and back to ON, the 000- digits appear and seem to be working properly (i.e. I can enter a program).
Any idea why and how can this be fixed ? hopefully without opening the case.
I looked into this link but didnt find the answer:
