I owned two Wegas, loved both. First was a 20", second was a 27" KV27FS13.
Had an issue with my 27", it buzzed for a while. The buzzing was brightness related, higher brightness = louder buzzing. It was a common issue apparently, IIRC it was supposed to be due to a power problem - flyback transformer maybe? Anyway I took it in for repair & they couldn't find anything wrong with it. They sprayed some dampening material on something & gave it back to me with a $25 charge, & it has worked perfectly since.
I sold it when I moved cross country, replaced it with a Samsung HD set. I still miss it at times. It's now on its 4th owner (I was the second) & still working perfectly.
