Unfortunately, that coax connector  is almost certainly crimped onto a cable inside.  You might want to pull off the back panel to see if that internal cable is screwed onto another jack on the chassis. If so, you can disconnect that end and substitute another cable, they come in several different lengths and are not critical. Any electronics store will have them.
If it isn't equipped with a connector inside, you will need to have someone unsolder the defective cable and install a new one.

Do you have a cable box or satilite box? You can come out of the box with the video output and into the tv and use it on video1 or whatever...and use it that way. Also a vcr will work the same way. Then your using the t.v. as a monitor and changing stations with the box. That's an easy "get-around" You just have to be careful when fixing the broken connector with a substitue cable. Some antenna inputs are isolated from ground, so if you use another cable, you will blow out the T.V. The isolator is usually a small 1 inch square box the connector came out of, then a small cable attaching to the tuner. If the connector was attached to the tuner itself, then you need a new tuner or a repairman to solder a new connector on. Don't try and solder one on yourself. I've yet to see that work be anyone other than a repairman. You could change the tuner yourself if you can solder somewhat well. Good-luck.

The coaxial cable antenna broke on my RCA tv


The part is called a Female Belling-Lee Socket. Radio Shack, or anywhere that sells antennas, CB radios, repairs TV sets, should have one. Soldering it in, is another matter. Be careful.

Input cable piece broke off akai pt5499hd


The coaxial input can be soldered back in. You will need a new one however. Sometimes the internals in the tuner (where coaxial goes) may be damaged when coaxial connection breaks out. If that is the case a tech may charge more money. But just to replace the connection should be relatively inexpensive.

The coaxle broke where you put the cable line on


The coaxial connects inside the set to the tuner. It needs to be resoldered in to the board & secured on the outside to the tuner. Its a quick fix at any tv repair shop. Unless u tried stick something inside & damaged internals of tuner

Broken coax connection on back of unit


If you are comfortable doing some small repair work, you might be able to fix this with stuff you have laying around.

All you need is:
1 - 8" piece of coaxial cable with male connector on one end
1 - set of RCA cables (Red/White/Yellow)
1 - coaxial coupler
2 - small wire nuts

electrical tape

Take the back housing off of your TV. You may have to unscrew the small nut holding the threaded connector to the TV. This threaded connector should connect to the motherboard with a male RCA prong that should be soldered to the component on the motherboard. You will need to carefully cut
& remove the old soldering & wiggle the connector off. This is the hardest part, but it WILL come off with a little trying.

Now get your coax cable and strip off about 2" of the black outside housing ONLY. Your solid copper` interior cable should be protected by a small plastic coating which is covered in braided wire. You'll need to be careful not to cut the braiding off. Untangle the braiding down to where your cut stops and try and get it all on one side of the cable so you can twist it all together and make a nice wire. Now strip about an inch off of your interior plastic sheathing to reveal the small solid copper wire on the very inside.

Get your RCA cable and cut about 6" off of the one yellow side. Follow the same process above to get a braided sheathing wire and a solid copper wire. Attach this yellow wire to the coaxial cable by twisting the two braided wires together and the two solid copper wires together. Use your wire nuts & electrical tape to secure your connections making sure none of the wires can touch each other.

Connect the yellow cable's male prong into the component on the motherboard and attach your coaxial coupler to the male end of your coaxial cable. If you saved the small nut from earlier, you can re-attach this new coupler to the housing on your TV. Screw your housing back on the TV and you should be good to go.

Cable plug broke off


Well first repair the coaxial cable going to your antenna. There is no way you can use RCA cables as a substitution for coaxial cable. They have totally two different properties. You can use the coaxial and feed it to a VCR/DVD player where you can output the signal with RCA/composite cables. Basically, use your VCR/DVD player as a tuner for your TV.

I BROKE THE COAX CABLE THAT GOES INSIDE THE TV TO CONNECT TO CABLE


You can run the cable signal into your vcr, and then use composite cables from the vcr to your tv (red, white and yellow). You will have to use your VCR to change channels though.

The silver box is called the TUNER. Call an RCA distributor, such as Union Electronics or Herman-Panson and order it by description by asking for the tuner for your model number. Have the location number on the board, just in case.

Snapped cable input


It all depends on what actually broke. Those input connectors are usually 90 degree metal units, soldered to the circuit board, so possibly the connector took a chunk of board with it. Any competent TV technician should be able to repair this in your home, especially if you tell them what the problem is when you call them. That way they will know what parts to bring.
