Those are the standard mains suppression capacitors that have been fitted to most electronics since the 1970s. They can fail and, when they do there's usually a bang and some smoke, but I would have though this TV was far too young for that. I wonder if this is tied in with a visit we had a year or two back to change out a board on our Beovision Eclipse TV as a "preventative maintenance precaution" due to a potential failure issue that had been identified? As I'm in the UK, our lovely new forum owners, Multicare, contacted us directly and came and did the job for free, but I wasn't home that day so didn't find out exactly what it was they changed. As the TV is fairly recent, I would say that your best port of call initially would be a B&O dealer if you have one nearby.  

Just replace those two paper foil capacitors. As said, it a common thing. I've already done some, these were also boards from BV11's. But also some psu's from Essence mk2's and ML/NL converters. After replacement the powersupplie will work again.

Thank you AdamS and Beobuddy!
