Facing TV Problems? Ask a TV Technician.
Hi, my name is ***** ***** I will do my best to help you today. To make sure I don’t miss anything, please give me a minute to review your question.
1- Could you please get me the model number written on back of TV?2- 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?These info will help to troubleshoot the problem.Thank you.
If TV gives sound problem only with cable channels but you get sound when watch DVD or any other video source then the issue would be within cable box which isn't sending out sound signals to TV and rebooting the cable box will fix 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, please try it now and reply back with the result and if problem resolved then a positive rating to answer would be highly appreciated.
I just got phone call request from your side, it would cost you additional $26 so please confirm to proceed OR feel free to ignore it if you prefer to troubleshoot the sound problem here in text chat.
Do you need any further assistance with this question?
OK, we need to try another video source to confirm the TV is fine or has got internal issue.
Is there any DVD player connected to TV?
If so, please playback a disc as a test to check sound output. Is it OK or still no sound?
Sorry about delayed reply, I was away from computer.
Since you get sound when play DVD that means TV itself is just fine and possible causes for no sound on channels is either cable box has got internal issue with sound processor and isn't sending out sound signals to TV OR the connection cable(s) between TV and cable box are not plugged securely/ tight.
I would recommend to check the cable(s) runs between cable box and TV to make sure it is plugged securely and tight, if all looks good then again reboot the cable box that should fix the problem.
If still no sound on cable channels then I'm afraid you would need to call your cable company to replace the cable box to resolve the problem. If you have any additional questions, feel free to ask. If you're satisfied, please rate me a 5-star at the top of your page. Thank you.
