When TV is off a relay clicking noise can be heard. Only stops when TV is unplugged. The TV comes on and works fine for now. Is it time for a new TV or can a circuit board component be replaced.
@firemonkey732 … relay clicks are associated with the power supply board. its hard to pin point the issue on intermittent symptoms. if and when the tv no longer turns on, this will enable you to determine what the issue really is. for now, i wouldnt worry about it.
