I have an odd problem. I recently acquired a Time Machine pin. Display 2 was entirely out, and the 6th digit of Display 1 was partially out (a few segments flicker now and then. It came on once after being powered on for a couple of hours, but hasn't worked since).
The seller gave me another display board; he was unsure of the status. I connected it, and Display 1 was completely out, but the others were good. They were also in better cosmetic condition, so I opted to use the newer board.
I removed the one-digit-missing Display 1 from the older board and installed it on the newer board in the Display 1 position. Weirdest thing! Digit 6 is now working, but digit 2 is out!
I checked the solder connections; everything looks good. I don't know anything about these displays. My best guess is I somehow damaged the display when I removed and reinstalled it, breaking digit 2, or there's a problem on the display board preventing digit 2 from working.
I'd like to think it's the latter. If that's the case, where do I start looking. What part, or parts would present with digit 2 not working?
Thanks!
