I have an LG tv. It is connected to the cable box with an HDMI cable. There is also an x-box connected to it. The picture works fine on the tv, but I cannot turn on the volume. The picture and volume works fine with the X-box, but the volume does not work at all with cable television (on any channel). I checked the menu and the speakers are on. When I use the remote for the tv, the tv indicates that the decibel level of the volume is rising but there is still no sound. The same is true if I use the volume button on the tv (picture indicates that volume is rising, but there is no sound). Is there anything that could be preventing the speakers from being heard on cable when they work perfectly fine with the x-box?
Model: Not sure
Unplugging cables. Checking the menu. Using alternate methods to control the volume -- cable box volume buttons, tv volume buttons, tv remote, cable remote.

Before we can begin I need more information:1. What is the model number of the Tv?2. IS the xbox also connected using hdmi?3. Who is your cable provider and what is the model number of the cable box?Please reply with all the information to get started trouble shooting.

LG - Model No. 37LE5300UC
Cable provider is Time Warner -
Cable Box is SMT_H 3050
X-box is not using an HDMI cable it's just using the gray cable that came in the box with it.
Ok thanks. The first thing you want to do is hard rebooting the cable box-Leave the Tv on showing the picture from the cable box.Find the power cord for the cable box, unplug the power cord, count to five, plug it back in.Watch the Tv screen as the cable box comes back on and hopefully the sound will be working.If that didn't work then reply here for more help.Mike
That did not work. I also tried changing the port that the HDMI cable was plugged into, which did not work either. Obviously the TV speakers are working because they work fine with the x-box.
So you either have a defective cable box or a defective main board in the Tv. You can do some more trouble shooting to figure it out or you can hook up the cable box using Component wiring and be up and working. Component connection is still HD, you don't loose any quality using Component connection.To continue troubleshooting the hdmi problem you need to find another device that has hdmi like a bluray or dvd player and connect it to your Tv. If it works then your cable box is bad. If it doesn't then the main board in the Tv is bad.If you find the cable box is bad then call Time Warner and get it replaced. If you find the main board is bad then a repair shop will charge about $350 to fix the Tv or you can buy the board and install it yourself. Here is an example of the main board (your FULL Tv version is required to get the correct board)- Buy Main BoardMike
Ok. I have an extra blueray in my office. I'll bring it home and plug it in tomorrow to try it. The tv in issue is my only stand-alone tv. All of my other tvs are imbedded in the walls and the components are all in an a\v room. The other tv's are controlled through my ipads via the Crestron system. I'll get a component cable and try it with the tv in issue as well. I don't understand how there can be a main board problem that relates only to HDMI, and not to other component cables but i'll try what you suggested.
Ok. I will be here. It is very possible for only the hdmi to have audio/video problem while the other inputs remain perfectly fine. Just curious- has this cable box always been connected to this Tv with hdmi and was working? Or is this a "new" setup?
