If you can adjust the diagonal noise away with fine tuning and retain enough color signal you may be able to get away with tweaking the hue/tint control and if that isn't enough eyeballing the color demod transformer...I've had to do the old demod eyeball adjustment on my CTC-4s it's not that hard....Granted if that test pattern looks perfect hue wise with video injection (haven't seen that checked yet), but looks terrible through the IF then that would be an IF alignment issue.
