Coaxial to component

If you hookup your TV directly to the coaxial cable, bypassing the cable-box, do you get a few channels? If so, then the coaxial cable is carrying a signal, which is good.

How are you hooking the output from the cable-box to the input(s) on the TV? Coaxial output port on box to coaxial input port on TV?
Red/blue/green "component" outputs on box to matching inputs on TV? Red/White audio outputs on box to red/white inputs on TV? HMDI output from box to HDMI input on TV?

You have to "tell" the TV which of the inputs:
* coaxial (with TV set to Channel 3 or 4)
* component
* HDMI
to "listen" to.

You can fix you have to follow this instruction

1-Reset the TV by unplugging its power cord for 30 seconds and plugging it back in. This is an essential troubleshooting tool as a simple reset often will resolve the great majority of technical issues experienced by any kind of TV. Power the TV on after plugging it back in and check the picture for any improvement.

2-Unscrew the coaxial cable that attaches your wall cable outlet to either the coaxial cable input on the plasma TV or to any digital cable converters you may use at home. Check the copper needle in the middle of the cable for any bending or damage and screw the cable back on the coaxial input. Again, check the picture for any improvements.

3-Secure the audio/video connection cables that attach the source device you are trying to watch to the plasma TV. This is a particularly important step if you use component cables. Component cables separate a video signal into different colors, so a damaged or loose component cable can lead to noticeable discoloration on the screen. Once the cables are secure, both in the source device and the plasma TV, check the picture again to see if this may have resolved the issue.

4-Scan your channel lineup and check the other TVs in your home to determine the scope of the problem. If you see the discoloration only on one or a few channels, and the same channels are discolored on the other TVs in your home, you may be part of a cable service outage and you will need to report the issue to your cable provider. If all the channels on the one TV have the same discoloration, and the other TVs in the home look normal, the plasma TV likely will need to be serviced for a problem with its picture components.

hope that it helped

You need to have a decoder box from a over-the-air (DTV), cable or satellite provider that has an HDMI, "S" video, composite video, VGA or component video outputs to connect to the TV's input. The coaxial cable only plugs into the decoder box. Apparently your TV doesn't have a tuner for coaxial RF.

Most old systems such as Mega Drive will come with an RF adaptor, which plugs into the back of the console and has a coaxial tip on the other end, to connect to the tv.

When you connect the coaxial end to the tv, you connect it to the round coax plug which is where you used to plug in your old cable tv hookup. It also might say Ant. or Antenna.

Turn on your megadrive and use your TVs input selector to change to either "antenna" or "tv" or "cable" input, or until you hit the input which displays your megadrive's signal.

Tip: use your TV's view options to change the input to a 4:3 or "not stretched" aspect ratio so that your old Fullscreen video games will not be stretched out wide on your new widescreen HDTV.

Good Luck!

U have HDMI ports,order HD from the cable or telicom compannies.Use a HDMI cable for the tv,also get HD channels.Do not have HDMI ports than ur Main signal board must replaced the Antena analog coaxial it broken.Well not able to buy the coaxial input for the antena along for part.

coaxial cables are great for HD boxes and usefull components like that but as for D.V.D... dinosaur feed!

get a converter from "The Source" that will convert coaxial analog to yellow component Video and rca audio. and you will be laughing :)


Trust me i am the flat pannel guru! :)

They don't make a coaxial to RGB or Component adapter. I know they make a coaxial to RCA. If you go that route you would just connect the coaxial to the video. Now if you do this not sure as to what would happen with sound, if you would have it or not. It is possible but not sure. The adapter I am talking about is called a
UHF Female to RCA Male Coaxial Adapter. Which can be found at most Radio Shacks. If this doesn't work I would contact the cable company about a cable box that they could then run the coaxial to and then the RGB or Component cables to the TV.

Hope this helps.

This part is called a coaxal RF connector.

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.
