Hi, all. I'm having an issue with a blank 10's digit on an LED display on my Black Knight. After swapping the positions of the displays around, I observed that the issue follows the display, not the player. So now I'm trying to pinpoint the issue on the display itself.
I have continuity between the solder joints of 15 - 8 and 15 - 10, as the schematic specifies for the 10's Digit Select and additionally, continuity between the pins on either side of those solder points.
Any suggestions on what else to test to diagnose the problem?
Thanks!
