Hi. I have a 32" direct view Loewe which I am very happy with. Last night I spotted black stains on top of the screen and they weren't there before, I am 100% sure. First I thought they were on the glass and would come off so I started to wipe the screen but it is like they are inside the screen! They don't come off... It can't be burn in, the set is 7 months old and calibrated properly with S&V disc. There is a lady coming for cleaning once a week, and she knows she mustn't touch any component in my HT area, but this week her sister came instead as she was sick. And apparently she cleaned the screen, because it was shining bright when I came in from work. But I don't want to blame her as I can't even think how on earth she might have caused such a thing. Any ideas/comments about what might have caused these terrible things?
