Having a nightmare with this. This TV Model 2019: UE32N5300 AK. I have a universal wall mount and non of the screws fit. I have M4/30 screws and also been told by Samsung support that M4/30 screws are the correct ones, but they are not. The length is fine, but the diameter is too big to screw into the back of the TV. So I have a TV that I can't put on the wall and no one, even Samsung, seems to have the answer. Can anyone help? Or I'll have to send the TV back for refund, which seems ridiculous.
