Motorola ts907 low hv

You need to read on how color TV works, again. In any case, if you have the color control turned way up and the oscillator is working you should get color
at some position of the fine tuning, maybe one with a really bad B&W image,
even if the IF is badly misaligned. Last spring I worked on the CTC5 at the ETF.
I got color, in fact good color, but the B&W picture looked even worse than
yours. I didn't have time to do an alignment.

If you don't get any color, the first thing is to bring the antenna of a regular
short wave radio in CW mode up to the color oscillator and see if there is
a whopping signal at 3.58 MHz.

Problems with the pulses generated by the horizontal output transformer
can cause no color to get through the color amplifiers. The feedback in the color area is so complicated that no color is a nightmare even with a scope. Wrong color is a lot easier.
