    Hi, My TV picture is being interrupted for anywhere from a few seconds to a
    few minutes by fairly heavy snow, and I'd like to know if and how it's
    fixable. It's a recent development, and I haven't changed or added
    anything electronics-wise to the room. The TV is an ancient color Zenith
    hooked up to Time Warner Digital Cable, but I don't think the problem is
    with the cable as I have a vcr hooked up to the cable too, and video is
    recorded cleanly. Playback from the vcr, however, also gets interrupted
    by the snow, as does the tv picture when I skip the cable box altogether
    and plug the cable directly into the TV. The picture is great, as it
    always has been, otherwise. I do live in an apartment building so I guess
    it could be something new a neighbor has that's causing the interference,
    but I don't have a clue what and I'd like to be able to go to Radio Shack
    to pick up something or other that would fix this if possible. Last piece
    of hopefully useful info, I have another ancient color Zenith in another
    room hooked up to the same cable line and I'm not having any problem there.

    Thanks for any help you can provide.

    You would be best to try another TV at the exact same connection,
    incase it is something like the cable splitter, a connector, or the

    Did you check that all the connections are good in you home?

    If the TV is at fault, this may be a failing component in the AGC
    circuit, or the RF amp stage in the tuner. If it is an involved tuner
    problem, the tuner module is replaced.

    It is also possible to have a cold solder connection in these areas as

    This type of fault is not going to be solved using parts from RS. You
    will need to have the set properly serviced if the fault is internal to
    the TV.

    In cosideration of the age of your TV sets, it may be a better decision
    to replace them with new ones than put money in to them.

    Thanks for the reply. Naturally I would replace the TV if it turns out
    that's the source of the problem. I am in the process of swapping out
    cables and connectors as you advised and have eliminated the possibility
    that it's the wiring. Swapping the TVs is unfortunately impracticable.
    I gather that even though this seems to my layman's eye to be a problem
    of interference, ie. someone in an apartment near mine added some
    electronic equipment that's interfering sporadically with my picture, that
    the reality is that's impossible unless there's something wrong on my end?

  4. When it happens, can you tap it on the side and get the picture back?
    How old is "ancient"?
