Question about LG 42PC3D 42 in. Plasma Television
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.
