TCL TV keeps flashing black on and off
My TCL tv keeps flashing black on and off. It's not a complete solid black, kinda transparent on the left side and transitions to solid on the right. It's happened a few times and eventually fixed itself bit has now happened again.
Sound is unaffected. Can't be the hdmi as it happens even when no cord is plugged in and the no signal screen comes up. Power supply is plugged into a surge protector.
