    How to troubleshoot no display on GE LOGIQ 100 PRO Medical Equipment?

      If your GE Medical Equipment display is completely black, several factors could be responsible. First, check that the power cable is correctly connected and that the wall outlet is providing power. A power supply issue or a defective PCB could also be the cause; consider replacing them. Ensure that the brightness and contrast knobs are properly adjusted. Confirm that the video cable connecting the Davinci to the monitor PCB is securely attached. Try feeding an external video signal to the monitor to rule out signal issues. If these steps don't resolve the issue, the monitor itself, the Davinci, or the FEB may be defective and require replacement.

    What to do if GE LOGIQ 100 PRO Medical Equipment has no echoes but the system is otherwise ok?

      Juan BradyJul 31, 2025
      If your GE Medical Equipment system is otherwise functional but displaying no echoes, the issue may stem from a defective HV Power Supply, a loose connection of the CA 30N cable assembly, or a defective FEB. Begin by inspecting the CA 30N cable assembly for any looseness. If the issue persists, replacing the HV Power Supply or the FEB might resolve the problem. In some instances, the DSP application may not fully load during boot-up; rebooting the system can rectify this.

    Why does my GE LOGIQ 100 PRO Medical Equipment show “No trackball Acknowledgement” error?

      Laura BradleyAug 4, 2025
      If you're encountering a “No trackball Acknowledgement” or “Trackball Interface error” message on your GE Medical Equipment, the trackball or its cable might be defective. In such cases, replacement is necessary. The keyboard, Davinci, or interface cable could also be at fault, requiring appropriate replacement.

    What to do if GE LOGIQ 100 PRO Medical Equipment shows “Keyboard not connected” error?
    • S
      Shaun RoyAug 10, 2025
      If your GE Medical Equipment displays a “Keyboard not connected” error message, the interface cable connecting the keyboard to the Davinci may be defective. Replacing the cable may resolve the issue. Alternatively, the keyboard itself might be defective, requiring replacement. If the EXT Video LED and the FREEZE LED are illuminated simultaneously during boot-up, this also indicates a potentially defective keyboard, which should be replaced.

    • J
      Jacqueline LopezAug 19, 2025
      If the GE Medical Equipment displays a “No System Mode Acknowledgement” error message, the Davinci interface may not be properly connected. To resolve this, consider replacing the FEB or Davinci PCB.
