Hi Anna.
Your case reference is 00355585 should you need to contact us directly regarding this issue.
Is the projector displaying an image at all? Do you know the model number of the projector?
If you are unsure which model of projector you have, please click here and look at the Promethean products and let us know which one you are using?
Does the projector have any LED's displaying? If so, which are lit up and is it showing a sequence?
Your ActivBoard that you are currently using, does this have power to the ActivBoard? Is the LED flame lit, if so what colour is showing?
I look forward to your reply.
