When I first turn on the TV (JVC AV-32750), there is a terrible noise coming from the speakers for about 20-30 seconds before it starts to subside. Once warmed up, there is no noise. I can even turn the TV off and then back on without problem. It sounds like electrical interference, but I don?t think that is the problem since it has worked for years in the same location. I have the satellite receiver audio hooked up the audio receiver for sound so I have the speakers turned off and the volume turned down to zero. Thanks in advance.

This model doesn't have a headphone jack. The only JVC TV in the series that does is the model AV-20D202. For the JVC AV-2732, use the RCA audio out jacks with an RCA to 3.5 mm adapter to connect to the headphones. The front audio jacks are audio in (for the audio from a video camera for example).
When you use any external speakers or headphones through the audio out jacks, make sure to turn off the TV speakers. Press Menu and navigate down to TV Speakers (up/down arrows). Then use the right/left arrows to select Off and then Exit the menu. Make sure you scroll the TV volume before doing this. Note: if your headphones do not have a volume control they are a bad choice for this type of audio output.
Ur tv turn on now,hear alot of clicking?The tv LED light "lamp" on front panel flashes or light up?The tv projection lamp is dead.The Ballast board dead too,if hear alot of clicking?The ballast board help to ignite the projection lamp.
Sounds pretty bad to me, I had a computer monitor that did a similar thing when plugged in after blowing, it's not a good thing. I didn't even bother to mess with it. You may have to replace the whole power board or at least have a whole handful of pieces to re-solder. It most likely isn't worth it unless your other tv's are under 30" and you don't have a lot of money ;)
it is due to degaussing circuit.
it has developed due to changing the side or turning tv or any thing is lying near tv which has got magnetic effect.
1 put of tv for 15 minutes
2 do not change direction while watching tv .
3 remove magnetic thing like speaker if is near tv.
still if you donot get the result call tech.to degauss it with degaussing coil.
it is 2 minutes job.
