What is ActivInspire?centering image on board

Hi Chloe, 

Thank you for posting your question. 
Sounds like either the board or the projector got knocked, have you tried moving either ever so slightly to fix the issue? 
If the projector has come loose, you might be able to shift it back and secure the bolts to keep it in place. 

I have opened a case for you under reference 00461046 should you wish to give us a call so we can talk you through it.
