I have an F Jack (coaxial) jack coming from a wall plate I want the video signal to go to a Sharp DLP projector and the audio to go to an amp connected to 4 speakers.   I need to find some way to convert the RF signal from an F-Jack to RCA or S-Video.

I have purchased an RCA CRF940 RF Modulator but I do not seem to be having any signal coming from the Audio-Video Output jacks after connecting the F-Jack connector from the wall plate. 

I know the best way to make the conversion is with a simple DVD/VCR combo unit however, I cannot find a unit that has an F-Jack IN/OUT.

If anyone has a suggestion or suggestions I would appreciate it.   By-the-way the RCE CRF940 also has S-Video ports as well.  I had the same luck with those.

Thanks in Advance

Welcome to the forum, john.

This is an interesting puzzle, indeed. First thing's first...what is the source of this video? You mention an "F jack"...that's fine. What is the origin of this source? ATSC? Cable? Satellite?

The source of the video is a set-top box provided by the local Telco which is the cable tv provider. The interesting thing is when I connect the F-Jack (F connector and coxail) directly to a television I get a clear signal, meaning a clear picture on the television with both audio and video.

Ok...I'm getting a better picture now.

You've got a reversed idea what that RF modualtor does. It takes an RCA feed and sends to out of the RF...not vice versa.

You will need to modify the in-wall wiring and the wall plate to accommodate RCA connections for this scenario to work.
