How do you receive your tv channels , antenna ,cable box or satellite box ?
O.k then as cable boxes are known to cause sound problems , the first thing to try would be a reboot ;
Pull the cable box`s power cord off the wall outlet (cable box only) for a minute.In the mean time turn off the tv and turn it back on only after you plug back the cable box power cord.Note that it may take a couple of minutes for the cable box to reboot after you plug it back ,just give it time.
Let me know how that goes

Did you reboot the box in the den ?
That is what we were talking about yes ?
If the reboot didn`t bring back the sound then you would have to try something else like a dvd or even an old vcr on this tv to see if it has sound .
If you have nothing else you could try then connect the incoming cable directly into the TV's cable terminal at the rear and set the tv to tuner/tv mode , there should be some channels in the lower bands and you`ll know if there is sound
If the tv has sound on any of those then the cable box is defective.
If the tv proves to be defective then the audio circuit is located on the main board and is not repairable separately which means the whole board has to be replaced and if you are not into repairing this yourself then you are looking at perhaps $200 + parts (average $80) in repairs at home and perhaps $50 less if you take it to the shop yourself.
For that type of money you could buy yourself a nice sound bar , you can get a very decent one for $120 .That would fix this problem along with giving you a better sound than original with the tv speakers alone and that can could even be used with future tv sets.
This sound bar would be connected directly at the cable box audio outs either digital or analog , all cable box have them beside HDMI
Even the TV's optical/digital audio out should still be fully functional , either ways you have a sound sourceThat is the workaround most often used nowadays.
