Not sure what model but there is a coil on some LG LCDs that needs to be replaced on the SMPS.

I suggest to unplug surround and sub woofer so you will get sound from front speakers only.

SOURCE: crackling sound from speakers, intermittent,

If these speakers are internal to the TV, chances are an internal component is getting noisy -- probably a capacitor -- and will eventually need replacement. That's not something you can do yourself. It's also possible there's a loose connection or a noisy volume control, but that's less likely, and again, would require a qualified serviceman.

If the speakers are external - that is, you've plugged them into the set -- check the connections at the set and at the speaker to make sure they're not corroded and are firmly seated. Sometimes just unplugging and replugging them a couple of times rubs off enough corrosion to solve the problem. Also wiggle the wires close to the connectors on the cables. If that causes the crackle, replace the cables.

Panasonic sa-pt860 speakers crackling


Panasonic SC PT860 Manuals
The above link is the owner's manual - it may help.
Here are some other ideas:
Try to find out if the crackling sound is coming from all speakers or just one - you may just have one bad speaker.
If the crackling happens at high volume settings, you may be overdriving the system - you'll just have to turn it down!
Try turning down the bass or the subwoofer level.
Is the crackling present with all sources (TV, cable, DVD, bluetooth)?

My hp mini sounds distortd when i play music like a crackling sound


update the sound drivers. most of the time when crackling happens it comes from bad drivers. if that does not solve it, then check the levels of the speakers. if all of that is fine then you may have blown your speakers from playing them excessively loud

No sound coming out of speakers


A quick way to check your speakers is to put the contacts from a 9 volt battery to the positive and negative speaker wires (briefly). You should hear a crackle of some sort if the speakers are functioning. If there is no crackle, speakers are bad / if there is a crackle, your head unit must have a problem.

Sound prob


Let me know what the Type Numeric Number and Model Number on the bottom of the laptop is. I can look on IBM website and see where the hard drive is in located to the speaker. It has happen on some HP and Toshiba I know from experience where the hard drive causes the speakers to crackle. Not sure why, maybe not enough shielding. The type has 4 Numeric Characters and the Model has 3 Alpha/Numeric Characters.

Let me know

After a while the system starts crackling and eventually sound deteriorates to thundering in speakers


Hi, I have exactly the same prob and I belive that it is in the amp module?! I am going to take mine in for repair as my other sony HT amp has just give up the ghost, (STR-DE435), it has a protector prob and is probably not worth repairing, although it is a great amp. If anyone knows the solution to this prob it would be great to hear it!!!
