Have TV Questions? Ask a TV Technician
Hello and sorry you're having problems.By far the most common cause of this problem, is a glitch in the cable box processing.Please follow the steps below:1) Shut the TV off, and then disconnect the cable/SAT box AND the TV from power (unplug their power cords).2) If using an HDMI cable, disconnect and reconnect the HDMI cable on both ends when the cable box is unplugged from power (make sure it's secure on both ends).3) Press and hold the power button on the TV itself (not the remote) for 10 full seconds while the set is unplugged, then release the power button.4) Plug the cable box AND the TV back into power, then turn the TV on and attempt to watch a program.
Usually it's the cable box- that's why I gave you those steps first. On the soundbar- let me know your results first and we can talk about that. Also please do not forget to rate my service- as that is how I am paid for working with you.

Please do rate me positively (at least 3 STARS) and I will continue with you on this as needed. The positive rating ensures I am credited for my work.
Do you need further assistance with this? Is the sound still out? Let me know please.
Have you tried a source besides the cable box like a DVD player???
