My fifth wheel has the 40" LED TV mounted on an articulated arm so it can be pulled out and moved around. Found out the hard way that the antenna cable Keystone provides is only 3' long and because of the location of the receptacle in the wall it has to snake around the mounting board before it connects to the TV and thus provides very little slack to the TV.
Long story short: while moving the TV the other day, the antenna cable was pulled tight and caused the threaded antenna mount to break off the TV.
Any idea how hard it is to find someone these days to work on a TV? After a number of phone calls and learning that a Sansui repair shop was a couple hundred miles away, I found a guy who looked like an extra on Duck Dynasty and whose shop was a bay in a mini-storage facility, but he was able to replace the item by taking the TV apart and after 2 hrs. & $75, it was good as new.
Immediately went to WM and got a 6' RG6 cable for $8 and the problem is now solved.
If you have that setup I would replace the RG6 cable ASAP.

Yes finding someone now a day is the key 
Luckily what you had was not a severe problem, on the inside of that coax connection is a short snub which screws on to the inside of that outside connector and goes to the receiver board inside. Interesting it broke off that easily
