    Why are the display and navigator pad not functioning on my TE TE3112?
    • K
      Kelly SheltonAug 25, 2025
      If the display and navigator pad on your TE Printer are not functioning, here's what to check: * If LED1 is not illuminating, the power supply unit or CPU PCB could be defective; replace the PCB CPU or power supply unit. * If LED1 flashes, a firmware update was unsuccessful; reload the firmware. * Check the cable connection between the PCB CPU and the control panel. * If there's no voltage at either measurement point, the power supply unit may be defective, so replace it. * If there's no voltage at one measurement point, the PCB CPU may be defective, so replace it. * If these steps don't resolve the issue, consider replacing the LCD Display or the PCB Navi Button assembly.
