Resolution

  • Try re-pinning bad pins in plug by pin-popping the pin out and clean off scorching if possible.  Bend pin back to reach proper pin height.
  • Or, contact Daktronics to order a replacement harness.  If shot clock's manufacturer date is prior to June 2017 will also need to order one (1) new main clock digit PCB and two (2) new shot clock digit PCBs.
