No more broadcast hd channels

We have this TV in our bedroom. Cable comes in directly from the wall (family room TV has the box). Anyway, I no longer receive the broadcast channels in HD unless I jiggle the coaxial cable where it enters the TV. My first thought was the cable, so I replaced that, but it did not help. Any ideas?

Scott, possibly broken solder/connection of the connector to the video board. you will have to remove the back panel and see how to get to the coax connector. If you can give us a proper model we might be able to help you a bit more. Also, once you have the back off, it might help if you post some images with your question. That way we can see what you see. use this guide for that.
