My JH has started making a pop noise. The pop occurs one time (in maybe an hour or two hour session), maybe ten or more minutes after switching off standby. No static or other unusual racket. This has occurred three times, while watching tv baseball and playing scales, so very low volume, no effects. Does anyone have any thoughts about the cause/cure? Original tubes. Thanks!
