Question about Televison & Video
There are different causes to this type of problem;
ONE: If coming from the loudspeakers you may have a power supply problem wherein one of the filter capacitors is allowing 120 cycle ripple to get into the audio amplifiers. If the sound goes up and down with the volume setting, it is in the lower B+ voltage area that feeds the preamplifiers to the audio amplifiers. If it does not go up and down with volume settings, it is in the main power supply - but the repair problem is about the same. The replacement of the caps is not much; mostly labor. The cap parts are only a few dollars.
TWO: If the buzzing sound is coming from within the unit itself it is likely to be a loose transformer. They are mounted on the metal chassis and sometimes one of the mounting screws will work loose and allow it to vibrate, causing a resonating buzz to make the chassis into a sounding board. The problem is solved by properly mounting the transformer. No parts are needed, only a remounting of the transformer screws that hold it down. This is something your depressed husband may be able to do by himself if he knows which end of a wrench and screwdriver to hold (I can give some detailed instructions if you think this is the problem).
THREE: AND, there are other possible causes of this noise you are hearing. As you may realize it is not possible to predict exactly when doing it from a long distance without seeing the unit and only going by your description of the symptoms. For example, it is possible there is a buzz coming from the video signal processor into the audio; it happens to some extent in some sets, and would require the replacement of some parts in the IC chip that handles those functions, but your description didn't sound like these symptoms.
Lastly, please note that before you do any of the above, just do a hard reset on the tv; unplug the power cord for 4 hours. That will reset the internal software codes and could, although not highly likely, restore the system if it is something in the video and audio processing functions.
I hope the above points you to the right direction in solving this problem.
