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

Not sure if this applies to your situation, but Plasma TVs use high voltage in their display systems, and static electricity builds up after 10-15 minutes of activity. Whenever the scene changes from a bright to a dark one, there is a voltage surge that causes sparks to discharge between the electrodes. This causes the crackling sounds you hear.

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)?

I have a crackling speaker on the left port of the bass box

The crackling sound on the left port of the bass box, indicates vibrating foreign matters inside it. Just open the box and clear it up. Put the sounds on. Listen if the crackling sound is audible. If the result is ok, then, close the box, and everything is alright..
However, if the result is otherwise, then, it is due to a defective speaker that needs to be replaced.

Sound fluxuates,crackling sound samsungTX-R3079WH sound goes up and down automaticly

If the sound FLUCTUATES up & down, try turning off the AutoVolume in the sound menu. You didn't say if it's one or all speakers crackling. Crackling is either a speaker or circuitry issue. Adjust the balance away from the speaker that crackles, if it stops, that speaker is probably "fried". If it still crackles, I'd turn off the speakers and run the sound thru a stereo for the quick, cheap fix. My Samsung (10+ years old to be fair) crackles due to a circuit issue but if I SMACK the left side speaker (behind which is the sound board and side panel connectors) it stops for a while. Maddening. I think I broke it squeezing it into the furniture it's in, pressing on the protruding RCA plugs. Dumb design.

Continuous crackling from TV speakers

I'm sure you have figured this one out. TV itself is causing the problems.
The circuit board that produces the audio signal seems to be the problem.
Before you call the repairman, go to the web site just to get an idea of what the parts will cost. That way he doesn't rip you off.

I hope I answered your question correctly. Please rate me. :)

Crackling sound when changing channels

Check the connections to the speaker and the receiver. Had a loose connection once that did the same thing.
