I have 14 promethean boards installed in my school. The picture on 5 of these boards has started to deteriorate. I would like to deep clean these 5 projectors, all are Sanyo XE40s. Is there a company that performs this service locally? Our school is located in Clonlara, Clare, Ireland. I also need to purchase some Activpen3s and nibs. Can this only be done online?
