Buzzing Sound Behind Flatscreen - Lights Dim Simultaneously
The Title more or less says it: Buzzing Sound Behind Flatscreen - Lights Dim Simultaneously. Heard it for first time today. Samsung LCD flatscreen hangs on wall - installed 2 years ago. Home built in '84. Not sure of wiring specifics. When the buzzing occurred a light on the same receptacle as well as lights in an adjacent room all flickered. This happened 2x's in 10 minutes - each lasting 2-3 seconds, tops. How worried should I be? If it recurs should I get an electrician - frankly I am neither knowledgeable or handy with such things.
