no, it would not be the demods,95% chance its a problem with the osc circuit, including A18, and the previously broken and replaced core, these are all symptoms of it not being able to be tuned into the correct range.

If you had a frequency counter or oscilloscope you could verify that it is at or near 3.57954 MHz but if its unable to get there due to come fault like in the coil, you will never get the color to lock in.
