Just got a new cable service through comcast. Have older tv that only has an RF connection in the back. Have set it up with the wall cable RF going to the cable box the out to the TV. Now am trying to set up the autoscan of the channels. On the back of the cable box there is no place to select channels but able to get a signal through channel 3. So now trying to scan the channels and the dvd/vcr is not picking up channels except for channel 3. What have step have I missed.
You can try going from the wall to the dvd/vcr first then to the cable box then to the TV.
It may find the channels but they might not be in the order you usually wouls see them i.e chan 4 may be chan 34 etc.
this will only work on an analog connection, if you have digital cable box it will not work.
other than that, you have to control everythng from the cable box and the dvd remains on chan 3 at all times.

RF MODULATOR HOOKUP For a TV with only a RF input jack, a RF Modulator can be used to hookup DVD players, DVD recorders and other devices which output RCA composite video and audio. For example, analog cable TV can be connected using a RG-6 type coaxial cable to a VCR or older DVD recorder's analog cable ready tuner RF input. Then as shown above, the output can be connected to the TV thru the RF modulator. The modulator outputs on channel 3 or 4 for the older TV so the TV is set to channel 3 or 4. Some RF modulators are built-in to Audio/Video switch boxes. These allow multiple RCA inputs along with RF input.
RF MODULATOR CLOSE-UP The modulator converts signals to channel 3 or 4 so older TVs can tune them on their analog tuners channel 3 or 4.
If your comcast box has video (yellow), audio R (Red), audio L (White) out, just connect RC cables to the input of the TV at video, audio-in RC Jacks. If your comcast box has only RF out, buy one RF to audio-video converter and then connect these to the TV.
Locate the TV's VHF IN [ANT, CATV, or 75(ohm)] or Cable Connector. Disconnect the existing cable wire from the TV's VHF IN. Connect the short, thick wire from the RF Switch (labeled ANT) to your TV's VHF IN. Reconnect the existing cable wire (disconnected in step 2) to the silver post labeled ANT on the RF switch. Connect the thin wire of the RF Switch (labeled Control Deck) to the back of the NES (labled RF Out). On the back of the NES, set the 3/4 switch so that it matches the channel of the TV. Note: The RF Switch does not produce stereo sound. To get stereo sound, connect your Control Deck to your TV or VCR using the Stereo Audio/Video Cable.
After the system is connected to the TV:
Insert the Game Pak firmly into the Control Deck. Plug the controller(s) into the front of the Control Deck. Use the far left port for a one player game. Plug the AC Adapter into the back of the Control Deck. Plug the other end of the cord into a wall outlet. Press the Power button on the front of the Control Deck. Turn on the TV and set it to the appropriate channel (3 or 4.) The game image should now be displayed on the TV screen. If after following these directions you are not able to view the game (for instance, if the red power light flashes off and on), try our Troubleshooting Tips.
use any other connections to your tv, not the one thru rf input. i.e: audio/video, component,hdmi, etc.looks like there is a tuner issue, plus you'll get a better picture quality by using other options. if that' hd set, you will take advantage of this feature, if not, just improved picture and no hassle to screw in that "comcast's" thick RF cable in. Good luck, Alex's TV.
If you used to put the TV on channel 3 to watch the videos that means you had this hooked up with the RF RG6 COAX cable. You most likely had this passing thru the cable box and then to the TV, but with the new digital format that may not work any more. A quick fix for this is to take the coax wire from the player and hook it up directly to the TV Cable port then flip your tv to 3 and it should work. If you have an older tv without the newer connections you may have this port already in use with the cable box - if that is the case you may need to get an RF switch or splitter. hope this helps
I ran into the same problem, Radio Shack has a device called a RF Modulator. The model # is Model: 15-2526 | Catalog #: 15-2526, the price is $27.49. On the back there is a place for cable in and cable out to tv. There are the 3 rca jacks on the back also, 1 video (yellow) and 2 audio (red/white) That simple. Set the tv to channel 3, turn on the dvd player and it automaticlly puts the dvd on the screen. Turn it off and back to normal cable. Works great, I use one myself. hope this helps. Steve
I don't understand why you would bother to scan channel when you have directv or dishnetwork??? directv or Dishnetwork required their units in order to watch any channel,which means: A. Depending on your TV setting,if you use RF connection from your basic directv to the tv,you would have to leave the TV on Ch.3 or Ch.4.to view the rest of the channels,you have to change it from the directv or dishnetwork box. You are NOT able to scan the rest of the channels from the TV,bottom line!! If you have comcast or your local cable provider,once you have activated,you could use the RF signal coming out from the wall plate straight to the tv and go to TV auto programming,it will auto scan the available channels for you. Don't waste your time on directv. If you are thinking about recording from your BASIC directv or dishnetwork box, you would connect SAT. signal from the wall plate to the directv box,then use composite video/audio output and connect straight to your VCR/DVD player under composite video/audio input. Now you could record the viewing channel to the VHS. Good luck!
