A TV should not black out like that. That is the menu and such should still work. Call it in and ask Samsung to fix it.
While turning on my Samsung smart tv (model UN55F6300AF) it blacks out when the hdmi cable from mxq tv box is plugged in. I have to unplug the hdmi cable and power off the tv and power back on again to make my tv work. Does anyone having this kind of issue or anyone know what's happening?
