I have a PRM-35 projector that when it turns on it just glows orange. It looks like there is an egg yolk in the lens. Any idea what might cause this?

Thank you for your post!
The issue could be caused by the cabling. The best way to find out is to remove the cable from the back of the projector and bring up the onscreen menu, can you still see the issue?
If so, I would suggest contacting Promethean Support directly with the serial number and an image of the issue:
