No sound for cable tv

I'm having a problem with my Tv. When I try to watch cable I get no sound from the tv. But when I play a dvd I have sound. It is obviously a soundcard problem but Where could I locate this soundboard, and where could I find a replacement?

Re: No sound for cable tv

Is this cable connected up to your TV set thruogh the tuner, the RF input, or the video and audio outputs, scart connector? You may want to make sure the cable box does not have a mute or a volume control turned down, and make sure the TV's audiop setting is not on SAP. Good Luck

Projection TV. DVD works. Cable often seems, "untuned". Static & un-fine-tuned sound of channel with black screen. Then, later, it will come on just fine. Sometimes, will go back to untuned status.

I would suspect your cable box first. I would unplug the power cable from your cable box and wait 60 seconds. Plug it back in and try to watch cable tv. I would also make sure the coaxial cable going from the wall to your cable box is connected properly. I would also make sure the cable going from the cable box to the tv is connected properly. Test your tv and see if it works correctly when you watch cable. If this fixes the issue you are good to go.
  • If this makes no difference use a set of new cables if you have them.
  • If this does not work then call your cable company. They may have to replace your cable box.

Sound won't work

If your TV has a picture but no sound, start by checking the obvious such as whether the mute button is on or whether the volume has been turned all the way down.

Next check your cable connections and make sure everything is plugged in tightly.

Change channels to make sure that it's not a technical difficulty with your TV service provider or TV station. Call your service provider to see if they're experiencing issues with their audio.

Try reconnecting the HDMI cable after you turn off the TV.

Make sure your remote is on the correct input, and see if you have sound while playing a DVD or video game.

For a simple troubleshooting checklist, see No sound on TV and get more details on some simple fixes for this problem. I hope this helps!

power in the tv has nothing related with the DVD. The tv has to have raster (white screen) even without signal (cable, DVD, others) if the tv alone is just having the led flashing and neither sound nor video (black screen) The tv has a short circuit in some of the boards that are part of the tv system. the blinking is part of a protection when the tv was created in the factory. Refer to the technician to repair this problem.

You need a audio cable for sound. HDMI cable is only for picture. I use the comp 1 plugs myself, better picture. I found with my TV that the HDMI cable is only good if you have a digital box for it. You can also use the plug to hook your computer to off your graphics card and watch downloaded movies on.
