Hi I have a 30 inch Cinema Display from 2006-ish. I have not used it for a while and when i powered it up again a few days ago it was kind of broken. There is no image from my Mac, only these vertical lines (check the photos). The lines change a bit if I move a window around and using a different Mac does not help. https://www.flickr.com/photos/69744417@N06/15415125321/ https://www.flickr.com/photos/69744417@N06/15231698748/ The screen itself appears to be intact. Does anyone know of anything I can try to get it fixed? Or replace a part or two?
