For the two newbies, go to Radio shack and get a 1/8" stereo male, that is used to replace a broken end on a headset. Also pick up some contact cleaner while you are there. Turn off and unplug the set, then take the spray, spray some into the headphone jack, then take the 1/8" plug and insert and remove a couple of times. Let sit for the cleaner to dry, then plug the set back in and see if it fixes it. If not, repeat process of the spray and inserting the plug again into the jack.
