Radio shack rf modulator model 15 1214

The RF modulator does not seem to be receiving power. The red light is not on. However when I plug in and unplug the receiver, the red light turns on for a split second. I do not believe this to be a split wire in the cord, as I have TWO modulators that are now doing this.

SOURCE: need cable connection circuit board for symphonic wf2702 television

I replace just the rf connector. You should be able to pick one up at you local repair center. If you did not damage the tuner which the jack will get solder'd into, you'll be ok.

SOURCE: do i need an rf modulator to install cyberhome dvd player to hd receiver?

Probably. I recommend posting a photo of the back of each unit. If the DT HD box only has an F coax connector for an aerial input, then yes, you'll need a modulator.

Transmits and receives no modulation out


I am not an expert but I think there can be little or no modulation of the carrier wave unless there is an audio input to the modulator. Like any audio amplifier a transmitter modulator (amplitude modulation) is quiescent without an input.

If the modulation amplifier and audio pre-amp are working and modulating the carrier wave and the antenna is ok then audio modulated radio frequency must be being transmitted.

It would be an extremely good quality CB that had a modulation meter. Mostly all they have is a meter giving an indication of the rf power being sent to the antenna and that rf (radio frequency) power would be the same whether modulated or unmodulated.
The modulation envelope, incidentally, is traditionally viewed or measured with an oscilloscope.

The indicated rf power could be verified using a field strength meter but the only practical way to discover if a standard CB is transmitting modulated rf is to listen to the transmission on a suitable receiver. If the squelch is turned down it will be obvious if the rf carrier wave is being received as the hiss would be silenced. If no audio is received it can be assumed none is being transmitted.

I suggest you try another microphone and lead and if that doesn't work it is clearly a job for a repair shop.

What to do if your TV won't take your Video/Audio cables


see, your DVD/Video device, outputs Composite Video & and an Audio signal, subsequently you must have AV inputs on your set they are Red & White (Audio) & Yellow (Video) RCA Jacks. If you do not have these then you are a bit stumped. You may however get a RF Modulator, this takes the Composite Video & Audio signal, and converts it into a TV Signal that can be "Received" on a TV Channels.
I have included a link so you understand what I am talking about.

Can't find where to connect for dvd. no white,yellow,or red plug.


Hello, Thank you for the opportunity to help

Sounds like you got a pretty old tv there, its frustrating not to see the RED/WHT/YELLOW plugs on it. This is because this tv was made when that was not out yet. So are you out of luck? No, you ar in luck but it will cost you a little money.

You can purchase one of these RF modulators at Radio shack for like $29.95.

OR

If you have a VCR, Generally they have these plugs out the back of them you would plug the DVD into the VCR in the Video IN. You're TV will need to be on channel 3 or 4 (dending on your vcr) You vcr will need to be powered ON then tuned to VIDEO INPUT. You can do this by using the remote's up/Down channels buttons or pressing input on the remote depending on the VCR.

The VCR will need to be connected to the TV's coaxe port on the back, That port looks like this:

If you do not have a VCR you would purchase a RF modulator you TV will need to be on channel 3! The modulator is connect to the port pictured above above. The DVD is then introduced to the ports on the back of the modulator witch looks like this:

Connect magnavox dvd to ge tv HELP!


You need to go get an RF modulator. They can be purchased at Radio Shack or a number of other electronic shoppes for a reasonable price.

The RF modulator connects to the coax cable connector and it has inputs for the RCA connectors.

Cheers ... Best wishes

On my new magnavox zv450mw8a i cannot get the vcr to come through the tv. i have followed the instructions on page 20 in the owners manual.what am i doing wrong?


I had the same problem with the dvd/vcr and my tv not communicating with each other even though they were plugged up correctly. I called the manufacturer phone # on the instruction manual. What they told me to do is strange, but it worked. They said to switch the bottom "in" yellow connector to the bottom "out".....and plug the bottom "out" yellow connector into the bottom "in". It worked on mine. Hope this helps.
