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.

I had my speakers 3/4 volume and they were fine. later they just started making a quiet crackling and the bass seems to not be in the sound, so it sounds tinny.


If you feel happy to do it I would take out a driver and try to look at the capacitors on the crossover for any leakage and if you have a multimeter handy check that the ohm's on the bass driver to see if they are within the stated range,a continuity test or a 9v battery across the bass terminals should tell if coil is broken,also is this just on the one speaker or both?

hi there,
The problem is actually from the speakers themselves. If it's not a year old you might want to bring it back to the store where you purchased it for a warranty repair or replacement.
Sadly the problem is inside the speaker and it could be a loose connection inside. If you're comfortable enough you can try to open the speakers and check inside for any loose wires which cause unstability of sound or for any loosed fittings from the magnet.
Hope this helps!

Crackling sound on boot up. goes away after a while


Crackling sounds are from poor connections. As the system warms up, the heat causes expansion and the crackling stops. You should remove and reseat the board in its slot, remove and reseat all connections between the board and the speakers, mics, etc. and restart. The sounds should have stopped - or been reduced considerably.

Please rate this reply - good luck!

Intermittent crackling sounds DPR 1005


This is an obvious thermal problem. Use circuit cooler to isolate the bad part. It could also be a crack in a circuit board.

Alternate warming with hair dryer and cooling one component at a time while listening for the noise.

Static from right from speaker


The noise is in the pre-amp stages of the Denon AVR. It might be caused by bad capacitors.
