        I've got one of them, too. Still have to give it a good whack
        about every six months.

        Long distance guess: The delay line is a device which delays the
        B&W signal while the color sig is being processed. The B&W sig
        is the brightness of the color picture. This probably got it's
        solder jarred loose.

        I may have the service manual. Send model number and I might be
        better able to direct you. Look for a component like "DL1". In
        Toshibas, I think it would be a little black "box", very narrow,
        standing on its side. About 1" high, 1.25" long.

        For the daring: wiggle it with a non conductive probe while
        watching the pix.

        Also possible, in view of the color problem - the little board
        on the end of the picture tube. Tap on that with GOOD
        insulation.

        Let me know if you need further by e-mail.
