Hey B&o enthousiasts!

I've bought a beovision 10-46 type nr 9566 recently but it has some stains on the screen, i added some pictures. But if i look closely it looks like some moisture on the glass, the screen behind it looks to be safe but I'm not sure. I want to be sure what it is before i take conclusions. So I want to open the tv but unfortunately I can't find any repair manual online. Does someone know more about this problem or have a repair manual/ progressive scheme? I'll be very happy if someone is able to help me! 😕

Thanks in advance!
