It sounds like a bad capacitor on the audio board or the speaker themselves are the problem.
I can't say it's 100% the problem because I can't actually look at the tv over the internet.
If by chance the TV is still under warranty, go that route.
If not under warranty and If you have some electronic experience, you can purchase a Service Manual over the internet and diagnose the source of the problem and fix it by soldering in the new part. The Service Manual will give you circuit diagrams, test points, and part# lists. Usually, cost under $20.

I hope I shed some light on the subject for you.

I'm getting a funny popping sound from the sub-woofer it appears; because when unplugged I don't hear it.


Looks like the capacitors on the amp are going.
If you hear a hummm sound when you turn it on without anything playing on it, then the capacitors are to blame for sure -> Time to replace the capacitors.

Logik LED TV making a constant tapping/clicking sound.


try turning off AND unplug for a couple minutes! USB may have pulled power down to start the switching noise. Try usb again and if it does it again then I wouldn't use that usb anymore.

We have a bottom freezer Kenmore refrigerator, and it makes a very loud tapping noise, almost like someone hammering. Then it will make on loud pop and quiet down for awhile.


Which is your model.
Also how about cooling temperatures are they ok.
Is the sound like the motor compressor hemmering or the fan blades hammer.

When the ice maker start to rotate there is very loud noise


Dripping sound.
During the defrost, water draining from the freezer section will drip into the pan by your compressor in the back and bottom of your refrigerator.
* Air rushing or blowing.
There is a fan in the freezer section and in some models in the back and bottom of your refrigerator to circulate air. This is a normal sound.
* Louder when starting or coming on.
Compressor operates at a higher pressure when first starting and noise should disappear as refrigerator continues to run and balance pressures.
* Popping, crackling, or sizzling about once a day.
If your model is self-defrosting, the defrost system utilizes a heater to remove the ice and frost from the freezer coil. During this period you will hear some expansion noises as heat is applied to the coil and you may experience some sizzling sounds as the melting water drips on the heater.
* Running water.
If you have an ice maker equipped model, the ice maker will call for water as the old batch of cubes is ejected and the ice maker starts to make more cubes. This will last for about 10 seconds and is normal.
* Vibrating or rattling noises

Sony Bravia XBR-2 32-inch LCD with popping noise problem


Unfortunately, we have the same problem. We hear popping and our sound goes lower. It is not the cable box for us, it's definitely the TV; however, it happens, on our set, after its been on for a few minutes and then goes away after half an hour or so -- however, this evening its been happening for the past hour and the TV has been on for the evening.

Popping noise


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.
