A bit of a half arse post i'm afraid,but just had one in 49" broken screen,sorry no model no,but cheap ish 4K set.Turns out these were sold with a 5 yr Curry's/PC world warranty,which includes accidental
damage.
Point No 2,under the stand three small screws,the rest appear to be clipped all the way around.
Now I've never not got the back off a set before,but this thing did not want to let go,got so far & clicked it back together.I think it would be very easy to break case or even screen taking apart.
Anyone else had a large screen Sammy like this?
