  8. Inspect Lamp and Filters: A failing lamp or clogged filters can affect image quality, resulting in lines. Check the projector’s lamp status and clean or replace filters as needed.
  9. Temperature Regulation: Ensure proper ventilation around the projector to prevent overheating, which can contribute to display issues like vertical lines.
  10. Professional Servicing: If all else fails, consider contacting the manufacturer or a certified technician for professional diagnosis and repair.
  11. Hardware Replacement: In rare cases, vertical lines may indicate a hardware malfunction requiring component replacement. Consult with technical support for further assistance.
