You're dealing with 2 circuits here, the horizontal oscillator AND the horizontal AFC. Best thing to do is disable the horizontal AFC, and see if the osc runs on/near frequency. You should be able to adjust it for a semi-stable picture (no synch) If that works, re-enable the AFC, and if it pulls you way off freq, look in that circuit.. If you can post that portion of the sch, it would help..
