"Another VIZIO turns off randomly"에 답변Check the back of your TV. Are the vent ports clean and free of lint? Lint build up will impede the airflow necessary for the interiors components. Clean them using a dust wand or a can of air. At some point it'll lead to a blown capacitor. That's noted either by a bulge at the top or a brownish substance. If you're handy with a soldering gun is a relatively easy fix. If not, then you would need to replace the board with the blown capacitor.
