My Samsung 65 inch was a few months out of warranty when a white dot appeared on the bottom of the screen. Annoyed me, Samsung said 12000 baht to replace the screen, without looking at it. I did not do it. A month or so later they called back and said 6000 to replace the screen. I have no idea how that came about but I did have them do it and it is still working after 4 years or so, but no Samsung ever again for me.
