I have had this tv for about 8 monthes. Ever since I have had it, there is a popping sound coming out of the speakers. Even if the tv is on mute, it still makes the noise. Do you know what could be causing this?

Re: Popping noise coming from tv
This can either be an connection which isnt plugged in all the way otherwise it can also be a bursted speaker which in the case means it's a great idea to get a seperate audio solution in order to provide you audio--unless you still have a warranty on it? If so, get it in ASAP since that can be limited.
a 6ya expert can help you resolve that issue over the phone in a minute or two.

If the amplifier itself is making the popping sound I suggest you disconnect it immediately, as it could be an electrical short within the amp. If the popping sound is actually coming from the speakers, it could be due to a crossed wire, blown amp channel, or blown speaker. If you posses the technical know-how, you can test the amp channel and speaker by connecting a different speaker to the channel responsible for the popping sound. If the new speaker makes the same popping noise then it is most likely a blown channel. I hope this helps =)
You have a problem indeed. try lowering the tv volume . if the signal is too high on tv it can cause some problem with the sound system if that dosent work then you may have some electronic sound output resistor problem.
That popping noise means the silicon grease underneath the audio ic has melted and is shorting the audio. This is unfortunately a design flaw by sharp. To fix the problem, you'd have to disassemble the entire TV and clean off the melted residue off of the AV Board and replace it with a new Sharp Heat Insulation Pad. Its a pretty difficult job, I suggest calling your local Sharp authorized service center to fix that for you.
Is the popping noise coming from the speakers? If it is, lowering the volume to zero does not stop the popping from the speakers, then you have an audio output failure. If the sound is not from the speakers, you probably have a high voltage leak. If this is the case, are you in a moist environment or using the set near a window??
Our Sony (almost new) is experiencing sound problems. The sound go off and on about every 10 seconds. Cords appear correctly connected. It sounds as if its coming from the television. Can you help with this problem? Thanks,
Has anyone heard of something like this where the cable box/service is causing popping sounds?
yes & it is common problem.
And is this something I should be concerned about causing damage to the TV's speakers?
not at all.
The Sony tech-support representative (over the phone) diagnosed it further to a problem not with the TV but with the cable box/service because there were no popping sounds when I played a DVD on my Playstation 2 that is attached to the TV.
they are right that your problem is not due to tv.
it is due to cable box/service?
but not defective it reqires to change the way you have connected tv to cable.please call tech to get it connected in such a way so that you do not get popping sound when you you put off cable box.
If the popping sound is NOT coming through the speakers, you probably have high voltage arcing. Probably close to the high voltage (flyback) transformer. If this is the case then other parts could be damaged if allowed to continue.
If the popping is coming through the speakers then you could have a problem any where in the signal circuits. Like a loose connection.
You'd need to have it checked out to find the problem.
Does the " popping" noise come through the speakers or from the TV chassis ?
If it is coming through the speakers you could have a bad solder joint somewhere in the tuning circuit.
If it is a snapping sound coming from the chassis, then you probably have something arcing in the high voltage circiut. If this is the case then you should have it checked out since this can cause other parts to short shutting down you set completely.
