Samsung LN-840950 Crackling Noise

by grinmoure / September 6, 2010 6:15 AM PDT

When I turn the TV on I hear a crackling noise. The noise is only present when the TV is on Component source(for cable). When on AV source, no noise. When I mute the TV the noise stops. When I take both Red and White AV cords out of the TV the noise stops. When I put them back in and take the same cords out of the cable box the noise continues. If I turn the cable box off the noise continues. When I raise the volume the volume of the noise increases. I've had the TV for about 3 years. Any thoughts?

Have you tried changing out the cables themselves? It is possible that there may be some damage on the cables or that the cables have degraded and is causing the buzzing you are hearing (which, from your description, actually sounds like interference).

update AND FIX!!!

I swapped out the red/white AV cords with another and no change - still crackling noise. I even reversed the cords, swapped red for white and crisscrossed the red & white and still same effect. The issue now seems to be whenever the AV cords are connected to the cable box, even if one red or white on one side is disconnected. The noise is also present whether or not the cable box is on or off. I'm going to power down the cable box and reboot it. IT'S FIXED! The problem appeared to be the sound from the cable box (digital/HD). Rebooting it fixed it!
