  1. This Tv set works fine for about 10 min and the color will go dark and
    everything else stays ok (sound). turn set off and immediately back on and
    it does it again after about 10 min.

    Do you mean the chromanence signal, or the complete pix? In this case, I
    would be looking for components that have become thermo sensitive with age.
    This can be in a fair number of places to effect the luminosity in a
    picture.

    The tech would have to troubleshoot the set by first determining the stage
    or area that is defective. Then he can proceed to find the components that
    are temperature sensitive.

    If you are not trained and experienced in TV service, this is going to be
    very difficult to find yourself. You would be best off giving the set out
    to a service centre for an estimate. There are many safety issues in
    servicing TV sets.
