My TV makes a staticky/crunchy/popping sound intermittently. Sometimes it lasts for hours and doesn't seem to matter how high the volume is. Sometimes it's days, maybe weeks in between when this happens. My husband read (or was told) that it was because of dust accumulating on a part in it and that the sound happens when it's burning the dust off. Sounds ridiculous to me. Have any of you ever experienced this and if so, what did you do? My TV is in a cabinet and takes two people to lift/move it. I'm sure my husband won't go for 'self-diagnosing' as some of you have - I'd be willing to if I could lift it without him knowing :-). But if you can give me a better reason than 'dust', he might be willing to try it. Thanks!
