The cable coax male connection is disconnected from the television

This is quite simple. Your wall box is a male connector. The TV input is a female one. Make a cable with resp; female and a male connector. Unless the wall box has a 'screw on' connector. (FC10 f.i.) Then you need this special item and/or crimp tools in order to fit this FC type connector to the coax cable. Not simple.

Female to female couplers will only connect to a male plug either side. If the two plugs are female you won't be able to do it, till you either change to two males or get a male to male coupler!

set should have 2 cable connecters; IF IT DOES NOT CONNECT VIA CABLE BOX/SAT BOX ETC TO ONE OF THE SETS OF AUDIO/VIDEO JACKS ON BACK OF SET AND USE IT THAT WAY----the AV jacks bypass the cable fitting.

Tuner could be removed and coax fitting replaced but just go around the problem.

If you do not understand, comment here and I will explain.

SD TECH

Tune the TV on and go to input set the input to cable. And set the unit to chanel 3 you should be able to get an image. Are you connecting the unit via rca cabel, HDMI, or coax cable?

You'll need to take it to a repair shop. There are high voltage capacitors inside a television which will hold a charge even after all power is removed. I would highly advise against making this repair yourself.

pls .check your tv power cabel pin and plugg bitwin sparked or luss canaction [pls unplugged cabel pin and see tv. power cabel pin on top side black spot.]
pls try power cabel properly canact if loose replace with new.
NOTE:most of tv poblum is making power cabel loose. so canacting tv power cabel or power bord check with electrician

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.

u can try to solder it back on

There might be a bad (loose) connection in the RF isolator or the tuner (both are silver boxes. Try to unplug the coax and bend the RCA tabs in so that the connection gets firmly made when reconnected. This may help. If it does not The connector may have to be replaced.
