Ideally the tv should be near the sofa. But if that is not possible then you can make a simple wooden shelf with the wood panel going right behind the tv. Something like this. You can make only one shelf but next to the tv not below it as it may hamper the movement near the dining table

ok pls provide me more details

Hi Hardin, You need to post a clear picture of your living room along to get it designed. Thanks and regards, Sujoy
