I'd like to repeat that it would be good to fix the tracking problem. If it's a tape speed problem, it should not affect the color frequency, but if it's a head speed problem, it could. So, fixing the tracking may solve the difference between tape and monitor (or may not). Now that you know how to adjust 688 kHz color frequency to cater to either playback or monitor mode, you need to find out which is wrong. I would guess that the monitor mode, based on the crystal oscillators, is correct (but I wouldn't say for sure).
