You have not given enough information.
Does your TV support connecting to the internet? In the UK such TVs are frequently described as 'smart' TVs.
Does it have an ethernet port?
You will need to re-ask the question, but state what the make and model is. If it is an unusual make and model it would also help if you described what its manual says about internet connection and what you have tried so far.
If you supply what you have tried so far then it will be easier for someone to judge your expertise and supply a suitable answer for you.
