    I have a Zenith SR2568S TV that has served me well, but I sought and
    found the Service Menu access key because I had a problem with reception
    on one channel. I have cable TV, but one channel drifts in and out of
    color occasionally so I thought there might be a way I could adjust the
    tuning of that channel in the Service Menu.

    My first question is: Do Service Menus have any means of adjusting the
    tuning of a single channel?

    My second question is: I understand the purpose of most of the menu
    settings, but those below I am not sure of. Could someone please
    explain what they are? Thanks.

    CAP Phase

    AC On

    Key DEFT

    Are you suggesting that this setting may be able to correct the tuning
    problem I had with the one station?? Or are you just defining the

    that fault does not sound like something which diddling with the
    service menu can resolve. try your cable decoder on another tv see what
    happens. Sounds like either trouble with the deco, or possibly a tuner
    /IF problem

    I take it from your comment that there is no adjustment for fine tuning
    the frequency for a channel? Ironically, after entering the service
    menu and leaving it with the settings NOT changed, the channel is now
    working better. Since I do not use a cable box, but simply the TV tuner
    to select my channels, I suspect the poor reception on the one channel
    might even be the cable company's fault. I know it has not improved due
    to anything I had done, so I am sure it is just a coincidence.

    Any idea what the abbreviations stand for in my message above??
