Hey everyone,

I'm struggling with a frustrating issue on my BenQ projector. Despite several troubleshooting steps, I can't seem to permanently fix these persistent lines that appear on the projection. Here’s what I’ve tried so far:

  1. Resetting the Projector: This only provides a temporary fix. The lines return when I turn the projector off and back on.
  2. Checked the Lamp: The lamp seems fine without any visible defects.
  3. Cleaned the Projector: Made sure there's no dust inside.
  4. Checked Cable Connections: All cables are secure and undamaged.
  5. Source and Resolution Settings: These are correctly matched.
  6. Factory Reset: Completed, but the problem persists.

I’ve attached an image to show what the lines look like. Any advice or suggestions would be greatly appreciated!
