Is my projector cooked?

Old Benq MP515 I currently use in my classroom. The dead pixels appear to be multiplying...

Assume it's a board not a lamp issue and is it likely to be sortable?

Thanks, thought it might be... New one on order : ) I don't think the hot temperatures here combined with it being moved around a lot do it any good, but it's pretty old anyway...
