    I have an older Magnavox 25TRC1 television, and I noticed that my
    remote control no longer works. I don't have the original remote, but
    I use a universal remote that came with my DVR. This remote has
    always worked, and I think that the problem is inside the TV itself
    since the remote works fine for my other devices. I've have had to
    take the remote control sensor out of the TV several times throughout
    the lifespan of the TV and clean it. I thought this was the problem
    this time, but it doesn't seem to be. I think that the sensor has
    finally gone bad.

    Does anyone have any advise (short of buying a new TV) on how to make
    this work? Perhaps someone knows where I can get a new sensor chip
    for the TV.

    tlhiv / Troy:
    As compared to the remote control itself, the sensor inside the television
    SELDOM is faulty, but it does happen. Before you jump through unnecessary
    hoops here, go to WalMart or Radio Shack and purchase a cheap universal
    remote.... as little as $5.... and try it with your television.

    Frequent removing/replacing the sensor may have caused tiny cracks in the
    print tracks near the solder pads.

    Thanks for the reply. I have a universal remote that came with my
    DVR. It has worked in the past, and the remote still works on my
    other devices (e.g., VCR, DVD, etc.).

  5. Have you made sure the thing is still properly programmed? Maybe especially
    if you've dropped it and the batteries have fallen out, or if you've changed
    the batteries. For that matter, if the batteries are getting weak, that
    also might cause the loss of the programming.

    I have a universal remote that I use at times, and it seems it can
    fall out of being programmed. At the very least, accidentally pressing
    the wrong button might explain why I have to reprogram it.

    I think this is more likely than the IR receiver, as someone else
    also pointed out.

    I have tried to reprogram it. I have a list of codes that I've tried
    in the past, and one of them used to work but not now. This thing
    stopped working when I was adjusting the color in the TV menu that one
    of my children messed up. I thought maybe I had changed something in
    there, but I have looked through the menus SEVERAL times and can't
    find anything that would indicate that I've disabled the remote from
    the TV.
