Incredibly harsh static on JVC AV-27750 television
James Posted Jul 03, 2008
Can anyone isolate this problem?
I left for 6 months and my friend used this TV. Upon return the picture is fine but the sound is so awful I can barely use the TV. It is loud overpowering static, occasionally interrupted by the actual sound of the TV program. It varies depending on channel. When I get the static on one channel I'll switch to another. Sometimes it's impossible to find normal sound on any channel, and even then it's temporary. It seems to depend on what is shown on the TV, if that makes any sense. When the screen switches to a commercial the static is worst of all. Graphics produce static on sporting events. The TV is completely silent upon startup, for several minutes. Then the static begins and won't relent until the TV is turned off. I've always liked this TV and really don't care about digital or HDTV newness. I just want basic picture and sound. Can this be repaired at sensible expense?

This kind of fault would strongly suggest that the audio output IC is faulty, the fact you state that the static sounding interference varies with programme content I feel is a bit of a misleading symptom, as the residual background noise of the various programmes will have differing levels, albeit this not so noticeable to the human ear! but this "will" be detected by current operated devices such as the audio output IC.
This of course is the simplest reason for the problem, and is the first thing that would be replaced to effect a cure, however if this proved not to be the cause of the problem it would then be a much more time consuming exercise, this being unlikely though!
