    1. To pin 21, input burst and chroma signals with the same
    amplitude of 100mVp-p (monochromatic, blue).
    2. Vary the phase of the above monochromatic color and seek
    the monochromatic input phase where the B-Y output
    amplitude of pin 43 reaches 0 (θB-Y).
    3. Vary the phase of the above monochromatic color and seek
    the monochromatic input phase where the G-Y output
    amplitude of pin 44 reaches 0 (θG-Y).
    4. Vary the phase of the above monochromatic color and seek
    the monochromatic input phase where the R-Y output
    amplitude of pin 45 reaches 0 (θR-Y).
    Also, in PAL mode, adjust the delay line using a Philips
    pattern signal with the IC mounted in the set and check the
    phase in the video input using either a PAL or 3N rainbow
    signal.
