Can't View TV Program When Recording With VCR

    I just purchased a Philips DVD/VCR, Model No. DVP3345V/17, for use
    with my Samsung LCD TV, Model No. LN-T3253HX/XAA and Cox digital cable
    system. Everything is okay except that, when I try to record a TV
    program, I get a blue screen. However, I can record the program and it
    plays back fine (both picture and sound). What do I need to do to be
    able to view the program that I am recording? Thanks.

    You're gonna have to tell us how this whole thing is wired. Cable directly
    into DVD/VCR? Cable into a cable STB? DVD/VCR -> TV....how? Etc....

    Okay, and thanks for the response. The cable is outputting to an RF
    modulator (necessary because my TV has only a coax input), the
    modulator is outputting to the TV, and the DVD/VCR's audio/video (red,
    white, and yellow plugs) outputs are connected to the modulator's
    audio/video inputs.

    Nothing going to DVD/VCR *inputs*?

    You say "The cable is outputting to an RF modulator (necessary because my TV
    has only a coax input.)" The RF output of your cable box is connected to the
    RF input of the modulator?

    I'm confused. I'm not familiar with RF modulators that have RF inputs. And
    since the DVD/VCR's composite A/V outputs (red, white, yellow) are connected
    to the modulator's composite inputs, there's no composite inputs available
    for input from the cable box.

    Suggestion: cable box A/V (composite) outputs to modulator A/V inputs.
    Modulator RF output to DVD/VCR RF input. VCR RF output to TV RF input.

    Methinks you're failing to tell us something here.
     
  5. This is a trivial matter. The antenna (or cable cable) connects to the RF
    intput, the RF output goes to the TV's RF jack. Simple. (I can't believe
    you're having trouble with something so simple.)

    The VCR shoulid have a switch that lets you choose between the antenna
    signal and the VCR signal. That's it. If you can't view other channels while
    recording, you're doing something wrong. And it's something very simple
    "wrong".

    The setup that I have is described here:
    http://hometheater.about.com/cs/dvdlaserdisc/a/aadvdrfmoda.htm

    So, the steps are:

    "First: Just plug your cable/vcr output into its cable input
    connection of the RF modulator and the DVD player into the RF
    modulator's AV inputs.

    "Second: Connect a standard cable from the RF modulator to your TV.

    "Third: Select either the channel 3 or 4 output on the back of the RF
    modulator."

    You seem to be suggesting that a connection is needed with the DVD/VCR
    A/V inputs. But, if that's true: (1) Why doesn't the above website
    mention it? and (2) How is the VCR managing to record if the
    connections are wrong?
     
  7. You seem to be suggesting that a connection is needed with
    As long as the antenna or cable cable is connected to the VCR's RF input,
    the VCR will record, regardless of whether the rest of the setup is
    "correct".
     
  8. Please pardon me, I am nobody from nowhere. If this doesn't
    No need to. I say dumb things once in a while, and I haven't left. Yet.

    That applies to playback through the TV's RF input, not to recording.

    The subject line reads: "Can't View TV Program When Recording With VCR". The
    modulator isn't needed for this. The tuner in the VCR and the tuner in the
    TV receive the same antenna or cable signal, and can receive any channel.

    Okay, guys, problem solved -- at least for my purposes. It turns out
    that my TV does have A/V inputs -- they were hidden by the way the TV
    was positioned on the wall. I therefore removed the RF modulator from
    my set-up, connected the TV directly to the cable box, connected the A/
    V cables that came with the DVD/VCR from the cable box outputs to the
    DVD/VCR inputs, and bought an additional set of A/V cables at Radio
    Shack to connect the DVD/VCR outputs to the TV inputs. Now,
    everything is working fine. Thanks so much for your assistance,
    although I'm still puzzled as to why my initial set-up worked the way
    it did. Is it because the VCR and RF modulator are analog and my TV
    set is digital?

    Ah, the OP said he had digital cable (and I assume a digital STB.) So, the
    TV tuner (his TV was old) *can't* receive any channel. Neither can the VCR.

    No.
     
  12. Is it because the VCR and RF modulator are analog and my TV
    You're kidding, aren't you?
     
  13. VCR.

    Okay, but then how was he able to make recordings?

    Don't ask me. I couldn't get him to tell me to what the *input* of his
    DVD/VCR was connected. I'll assume it was modulated, and the DVD/VCR was
    tuned to the same channel as the modulator output. But anything is possible,
    considering he didn't realize his TV even had A/V inputs. Sigh...

    I told you in my second post what the set-up was: The inputs of the
    DVD/VCR weren't connected to anything. However, the VCR could still
    record -- it's just that I couldn't view what I was recording.
