    Is the high-voltage OK (26-28KV) ?
    Are the CRT heater filimments glowing ?
    Is the G1 voltage OK (-20 to -60 V) ??
    Is the G2 screen voltage OK (350 - 600V) ??
    If above is OK, try connecting a 1K resistor
    for one of the video color cathode pins on
    the CRT socket to gound. The screen should
    turn on with that color.
    Hope ythis helps....
