Hi there and welcome to Just Answer. My name is Steve and I am one of the TV experts here. I am in Maryland and have been helping customers like you on this site since 2005.


As we chat, please allow me time to research and type in an answer to your messages. I am a real technician so this can take a few minutes.


Let's get started! Are you saying that the coax terminal that sticks out the back of the TV has snapped off? I just need to be sure before we proceed.


Please let me know at your earliest convenience so that we may continue.

If that is the case, then you will need a replacement Main Board from that model of TV. Someone is selling on HERE. You would need to get that, open up your TV, and swap out the board. It is not a simple project by any means but it can be done.

You could also pay someone to do it for you. I would think it would be a $100-$150 job plus the cost of the board. IN all honesty, for a 42" TV, you can pick one up with a built in Roku for under $200 at BEST BUY.


Please let me know if you need further help. I'll be here.


All the best.
