Facing TV Problems? Ask a TV Technician.
Hello and Welcome. My name is ***** ***** I'll assist you today. I'm reviewing your question now, and will post back with your reply ASAP.
- What video devices/ sources (such as cable box DVD player etc) are connected to TV and does the problem occur on all video input sources?Thanks.
Just to clarify, you get sound when playback DVD disc and HDM box means Cable Box connected to TV through HDMI cable and TV doesn't give sound on cable channel, is this correct?
OK, this kind of problem mostly occurs in cable box and sound processor chip in cable box gets error and sound gets mute. Reboot the cable box that will help to resolve the problem.
- Have you tried to unplug TV and cable box power cords from wall outlet for 10 minutes to reset, replug back in, let cable box reboot that may take several minutes and check?If not yet, can you try it now and reply back with the result and if problem resolved then a positive rating to answer would be highly appreciated.
