This isn’t a LED sequence I’m familiar with.
If you have an issue with the projector, try removing the power cable for 30 minutes and then connect and test again.
If you still have the same LED sequence, try and replace the lamp just in case that this is at fault.
If this doesn’t help, record a short video showing this LED sequence and contact Promethean Technical Support directly and provide your serial number so we can further advise.
