Connect Coax Connection to RCA Connectors

I read this thread:
https://www.doityourself.com/stry/ho...o-an-rca-cable

After connected as instructed... I can play a DVD thru this connection; But the signal from the coax-connection is not passing to the TV. Help?

Can you provide a photo showing your connection?

That article is a little dated. There are no coaxial to RCA plug converters that I know of.

Your DVD player more than likely doesn't have a coaxial output which means you'll need to use the composite audio and video outputs. Unless the TV is a little junker it should have composite audio and video input jacks.

Does the DVD player remote have a switch or button for DVD/TV? See if pressing that will get the signal from the coax to the TV..

I would think that pressing Stop on the remote would accomplish this but maybe not.

Double check to be sure that the signal from the coax works when that coax cable is screwed directly to the TV.

We can see a DVD player in the picture.
Can we assume that you have connected the "OUT to TV" RF jack to your TV and on channel 3 the DVD is playing ok ?

Many players will carry the RF connections thru when you power it down. Some have a setting in the setup menu that can change when it connects.

You need to make sure whatever you connect to the "IN from ANT" is on channel 3.

You're showing the back of two different DVD players.

I think you are trying to use the DVD players as an RF modulator. That is probably not possible.
You are sending a signal in but that is not getting processed inside the player.
It's just being switched to the RF out jack.

In other words...... on the RF out jack...... you will see either the DVD player OR whatever is being sent in the RF in jack.

Does the TV have a screw on jack (stud) just like the UHF/VHF jacks on the back of the DVD player?

Does the white coax cable work correctly when screwed directly to the TV?

I never though this would get so complicated! Don't kill me... But there is another device(s) between the DVD/VHS player and the TV:

We're not going to kill you but we can't help you when we don't know exactly what you have.

That is a composite video wireless link. Not sure what you'd be using that for.

What signal does/should the white coax cable carry?

If ou take away the DVD player and connect everything else up, does the white coax cable work correctly? y

>>>The TV is across the room from the cable-feed; And no way to extend the coax.

Ok..... so the cable box is connected to the wireless transmitter.
The wireless receiver is connected to composite LINE IN on the TV.
That means your TV has an antenna connection as well as at least one A/V input.

The channel you want to watch has to be selected before getting to the wireless transmitter (box in the middle of your diagram)..

In your blue diagram where is the cable box?

An old VCR might not be able to select channels from a cable TV inlet coax that delivers digital video.

You should run a controlled test. Connect the white coax cable to a cable TV box. Bring a second (probably smaller) TV over to the side of the room with the cable wall outlet. Connect the TV video in jacks to the cable box video out jacks using RCA cables. If this does not work then something else unrelated to the DVD player and wireless transmitter is wrong.

At least we proved that the cable is still live.

Short answer beyond this point is still, you need a proper cable box.

Long answer where the final result is still not guaranteed:

(first of several one step at a time tests)
Connect the long temporary coax cable to the back of the DVD player VHF UHF output to TV.jack,
Connect the other, short, coax cable from the wall outlet to the DVD player VHF UHF in from antenna jack.
You should find that you still get the program on the TV and the TV channel selector still works when the DVD player is turned off.

Turn on the DVD player.
Set the TV/DVD toggle (single button on remote, may be labeled TV/VCR) to DVD. You will have achieved this when the TV remote will no longer let you flip through channels on the TV (or if the screen goes blank after working properly a moment ago).
There should be a Channel 3 Channel 4 selection in the DVD player menu (or a switch on the back of the DVD player) .Choose one and match it on the TV.
Now you should be able to bring up the DVD menus on the TV.

There may be a DVD menu selection for Antenna or Cable or U-Band or OTA or CATV or things like that. Try different ones.
Flip through the channels using the DVD player and its remote.

If nothing works then try a different DVD player or VCR.
As you can see there are many different combinations and permutations to try. In all cases the TV must remain on either channel 3 or channel 4 to match the DVD player. Still, most likely you will not be able to select all of the channels via the DVD player (or VCR).

We have not reconnected the wireless equipment yet. We will get to that after you got it to work using the temporary coax cable.

Medium answer: Install the temporary coax cable permanently. Most likely the cable TV picture quality will be better compared with going through the wireless equipment.

Update...

I did the coax-to-coax as below - Worked. But no combination of inputs/outputs on the DVR/VHR remote would switch to the DVD(actively playing).

I then connected the wireless as below - DVD worked as did the coax-to-coax.

Allan: You provided the solution... Channel 3 on the DVD-player. Thank you for your patience with me.

"There should be a Channel 3 Channel 4 selection in the DVD player menu (or a switch on the back of the DVD player) .Choose one and match it on the TV. Now you should be able to bring up the DVD menus on the TV".

Other, obscure, advantages of putting the DVD player up front, under the TV.
1. The remote might be unreliable pointed in front of you and having to bounce off the front wall to activate the DVD player behind you.
2. DVD pkcture quality is better still when you connect the DVD player to the TV using the green, red, blue jacks (and another red.white cable for the audio). You still need the yellow, red, white jacks to play video tapes.
