Speckled whiteboard display
For the last few months my projector has displayed salt n' pepper pixles on my board making it difficult for my students to see what I project. Can someone please advise me how to fix this problem.
I really love the board and unfortunately do not want to get rid of it especially since my school has little funds to pay for a replacement.
I do hope the fix is easy and something I can do on my own with little help.
Looking forward to getting a response.
