Facing TV Problems? Ask a TV Technician.
Hello, I'm Shahid. Sorry to hear that you're having trouble with this but I'll do my best to help.
- 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?Thank you.
OK - Have you tried to unplug TV and Roku box power cords from wall outlet for 10 minutes to reset, replug back in and check?If not yet, please try it now and reply back with the result.
Phone call assistance would cost you additional $26 and we can troubleshoot it here in text chat format if you prefer it.
Please check TV menu for TV Speaker option that should be set as ON.
Please find TV Speaker or External Sound option in TV menu (sound or setup) by using TV Remote and select TV Speaker/ Internal Speaker instead of external or any other thing to enable sound menu and sound output.
Is there any other video source to connect to TV as a sound test?
OK, that would be fine to fix the sound problem.
