Hi, my parents Beovision Avant 4K tv has also a similar problem. Since one month the screen got all rose/pink patern. The resailer couldn't give them a date of repairment, but i'm worried about the cost, since the tv is out of warrenty, it was bought in 2015.
How can they avoid paying, since this issue seems to be often happening to this tv model?
It should be covered by B&O themselves
