Since you aren't hooked up to see a picture, everything you just wrote makes sense. Good luck.

Try to get the luminance channel working first. Inject a signal into the tuner from a DVD player or Analyst, and scope the output of the video detector. With the horizontal section disabled, the AGC circuit isn't going to work, without a keying pulse; you'll have to use a bias box instead. If you have no video at the detector, the problem is "upstream", in the IF strip or tuner.
