    Digital and Analog question

    I'm trying to help a friend ................
    He had an old TV running off a roof antenna - - Now, everyone needs a converter box for analog tv reception......instead of paying for that, he bought a digital flat-screen TV. He's trying to tape programs from the digital TV to his "old" VCR, and is getting neither picture nor sound to record on the VHS tape.
    Is the old VCR the problem? We've tried every hook-up from red, white, and yellow rca-types to "super tv" cables, to the screw-on tv cables, and so far,
    nothing has recorded. The TV picture is clear, and the hookup female plugs are there.........still, nothing.
    Is he simply stuck with buying cable or is there another solution? Any ideas would be appreciated, and thanks for past help.

    Re: Digital and Analog question

    In order to record the digital TV signal on the VCR you would need a digital tuner that provides an RF frequency output.
    I suspect that the output of the digital tuner in your TV goes directly to the circuits in the television and that the TV connectors are inputs only.

    As Stuart suggests, you need to get a modulated output from the TV and I doubt if you have one.
    I believe the red and white connectors are (stereo) sound, and the yellow connector is a composite video signal which is not compatible with your VHS recorder, and which is expecting a signal from an analogue aerial into its own tuner.
    If the VCR has no other inputs (other than the aerial) you would need some kind of digital to analogue (SCART to RF) adapter to record from the TV's tuner (if such a device exists), or it may be simpler and cheaper to find a digital tuner that has an analogue output and use that to feed the VCR.

    Alternatively get an aerial splitter/amplifier and put a separate feed in to the VCR (putting the digi-box after the splitter as well).

    Re: Digital and Analog question

    I read from the original post - "...a converter box for analog tv reception......instead of paying for that, he bought a digital flat-screen TV..." - that the digital decoder bit is incorporated within the TV itself without there being an analogue output.

    (I suspect the aim is to be able to record digital channels...? <img src=/S/shrug.gif border=0 alt=shrug width=39 height=15> )

    Note to self - must get eyes checked and re-connected to brain.

    I think the answer is that the OP will not be able to record to VHS direct from the TV. A cheap digi-box might do the trick however. To the original poster - you will almost certainly find that the quality of VHS when viewed on a large screen TV is disappointing to say the least.

    Our solution involves a TV tuner card, a PC (well 2 actually!) and a lot of HD space!

    Re: Digital and Analog question

    By February 9, 2009, in the US anyway, ALL TV stations will be required to switch from analog broadcasts in the VHF band to Digital broadcasts ( mostly in the UHF bands ). Practically all of the stations are now simalcasting in both bands in order for people to test reception in the new bands. Users that have cable or satellite TV servers will not be affected by this change. People who receive their signals from external outdoor antennas or "rabbit ears" must either replace their TV with a digital receiver or purchase a DA
    ( digital to analog ) converter box in order to continue to use their outdoor antennas. IF ( and I repeat, IF ) reception was good in the UHF bands, channels 14 and above. then a converter will work fine without having to change the TV set. IF UHF reception was poor, then you are "up the creek without a paddle".
    Unfortunately, I fall into the latter category. I had great reception in the network VHF bands using a deep fringe antenna and a good high gain amplifier BUT UHF was spotty at best due to the distance from the transmitters. I got a converter and tested it out and sometimes it worked fine, others were a forget about it read a book night. ( not too bad an option anyway ) I don't want cable, so I guess satellite is the way for me.

    To get back to the OP question, I think the jacks on the new TV are digital jacks which are not directly compatible with the older VCR analog cables. PERHAPS, a DA box hooked into the new sets jacks and then fed to the VCR would work? The boxes ( with the government $40.00 rebate card ) are only a few bucks and probably worth a shot.

    Re: Digital and Analog question

    If the TV has RCA-out (it is not obvious that it would have this) and the VCR has RCA-in (pretty standard) I would expect that to work. Can you hook the new TV's RCA-out to the old TV's RCA-in to see whether a signal actually is being sent?

    Re: Digital and Analog question

    Who makes the TV ?? You might check out their website for any connection guides they may have posted.

    Otherwise, take a look at this article for a written explaination of the process. Or these instructions for using an RF Modulator.

    Or there are instructions with pictures here for connecting a Digital Converter box into a system, but states that a Digital Converter Box is nothing more than a digital TV so you should be able to adapt the instructions to fit your situation and get things working. Good luck and let us know how you make out. <img src=/S/smile.gif border=0 alt=smile width=15 height=15>

    Re: Digital and Analog question

    The TV is a Visio, and the VCR is unknown to me, but is pretty old (like 6 to 10 yrs), so I'm pretty convinced that they're going to end up uncompatible.
    I'll double check his connections to make sure that the "ins and outs" are not crossed-up, then we'll see what happens. Thanks for all the input,
    and as usual, you guys rock.
