hdmi no signal but component input works

Both the HDMI inputs are not recognizing ANY cable input, either from my receiver, direct from the cable box, or direct from a PS4. (separately or all together) They have worked just fine for 4 years. As of last night, not so much. The tv just reads that there is nothing plugged into it (whether it's HDMI 1, 2, or both together). If I connect the cable box to the tv through component cables, it works just fine, but ONLY if the HDMI input cables are unplugged. If the component cables are plugged in at the same time as any of the HDMI, none of them work. We have had some issues with the HDMI cables where they connect to the tv. If they are wiggled or played with at all (i.e. telescoping the tv out from the wall mount or tilting it, etc.) the signal from the receiver cuts out until they are adjusted (at the point of connection to the tv) to where the signal comes back.

I can only assume that it's the HDMI connector panel on the tv that has to be replaced/repaired. Ballpark figure, what does that run to repair? If that is the problem?
