Bought new 2015 and not problem until 2022 when like others get sound but no picture - reportedly an acknowledged problem on the main board. The picture will return after 1hr to 10 hrs seemingly depending on heat of main board as when sun heats the tv in morning it comes on, but other parts of day it won't. Now 7 yrs old the picture is still beautiful for bright scenes, the local dimming and contrast limits of IPS panel from 2015 of course means blacks are not true black and you can see the local dimming is not sophisticated compared to new models.

7 yrs in and still going strong. Until the other day. Sound and no picture. Stills work pic etc But in motion nothing for about 30min to 45min then comes good.
