I have an extremely annoying high pitched whine that occurs when the TV is in game mode using my Xbox XS. I reported it to Samsung in February (under warranty) and had a tech come three different times. First time he replaced the mother board (didn't work), second time replaced the power supply (didn't work), third time replaced the display. After replacing the display, the noise had gone away. I don't play the Xbox often (I won it) and when I turned it on 7 months later, the noise was back. I called again and they informed me it was out of warranty but after explaining it was the same issue, they had a tech come at no charge. The tech replaced the motherboard again and it still made the noise. Samsung issued an exchange number and called me to inform me I would only a prorated amount as a refund ($500 less than I paid 14 months ago). I escalated it to the "Office of the President" and Milargos still refused to refund the full amount even though I reported the problem during my warranty period and it still had not been fixed. I am extremely frustrated since it is a major hassle to take down and put up the TV since I can not do it myself. So now I must figure out how to get it down, then they pick it up, I only get a partial refund, and I have to buy and mount a new TV. Does anyone know how to fix this? It blows my mind they are willing to loose a loyal customer over $500.
It's not the Xbox. Multiple people have had the same issue with the TV, even when not using the Xbox. It is something to do with when the higher refresh rate is used. Also tried different wires, same result. My major gripe is that they don't honor their warranty because they are saying the ticket submitted during warranty was closed and that it was not reported AGAIN until after the warranty period (2 months after). Bottom line is that it was reported during warranty and was never resolved.
