Recently lost sound. Couple of nights it did come back but now no sound at all. Funny thing, can record shows with cable box and when box hooked up to another TV show plays with sound. TV 4 years old

Enter its sound menu, and check it. If muted, as you know there will be no audio output. If not muted, check the speaker/s. If found OK; check and replace the damaged component/s at its audio output section circuit board. If needy, replace this board as card basis.
