Haven't dug that deep into a deck that old with that issue but if I wanted to figure out which board(s) are involved I'd trace the control track wiring off the stationary head (which also contains the linear audio head on most decks) to a board and also trace the head drum and capstan motor wiring to a board. Those boards are likely involved. The older the VCR the more spread out the circuitry the first models may have read the control track on one board and passed it to 2 separate servo boards, the most recent ones did everything in the entire deck on one board. How muchand what was on one board in early decks sometimes has more to do with how compact they could build it by putting things certain places than logical placement.
If there's block diagrams in your service literature that may help you find things too.
