There a number of variables at play here! Yes the alignment may be out. But the oscillator may not be at 93MHz. Maybe Chris tuned to an image or harmonic? How certain are we the oscillator is correct?
Certainly the fine tuning test will show if we are in the ballpark. If the video carrier is not on the slope at 50%, the picture will be smearyand awful anyway.
I see impatience here. Too often I see the knowledge we have gathered taken for granted.
If the alternative is to feed the video amplifier, fine. But will no contrast control in this set to set level and assuming the output composite analog video polarity of say a DVD player is negative sync you may not need to invert video. Is Chris up to devising a way to interface the video and manage signal level?
It seems simpler to me to resolve the relative simple problem the set has rather than introduce another problem. Maybe the best way is to let somebody else work on it.
