Buzzing/fizzing noise from back of sony flat screen tv

Posted by techwurx on Oct 23, 2009

Maybe some clarification could lead to more peace of mind. Just as an FYI: Many power supplies inside such units today will generate a very low buzz as it converts wall power to DC inside and generates a "buzz" in some cases to do so. However if the noise is objectionable when listening to TV sound it may be a filtering defect. Interference: It is possible some other device nearby or plugged into the same outlet is simply creating interference. You can try ensuring no other electronics are close-by, using a different outlet with nothing else plugged in, or a good power strip. Also if the unit has a three-prong plug be sure that all three pins are connected to a good grounded outlet to get best (and safest) results. If that is no help: Do you know anyone else with same TV model you can check with to hear what theirs does? Or any same model units in a store nearby where you may be able to stop by and check?
