Troubleshooting Recommendations:

  1. On the Galley Control Panel (GCP), navigate to home, CMS equipment page and look at the system status.
  2. If system status is reported "ready", proceed with step 2.
  3. If another system status than "ready" is reported, follow the appropriate procedure.
  4. In case a DRM logo is displayed in the upper right corner, follow the appropriate procedure ("GCP displays DRM-logo on equipment page").
  5. Assign a source video signal (i.e. BDP video) to LCD and a PSM and check if it is displayed correctly.
  6. If source video signal is not displayed correctly on LCD and PSM, check the source and follow the appropriate troubleshooting procedure.
  7. If source video signal is not displayed correctly on LCD or PSM, check the wiring interface between the affected components. Pay close attention to the routing of the harness.
  8. If source signal is displayed correctly, continue with next step.
  9. Do close out.
