Hm, both the ones (PAL AG7350) we have here have developed two other issues but not tracking problems.
Firstly there is
some image disturbance on VHS (but seemingly not s-vhs) tapes. More recently the one I was using has started shutting resetting most of the time when trying to start playback. I haven't found anything about either issue online. I already checked for bad caps in the power supply (and replaced a bunch I probably didn't need to as most seemed to be good) and the video boards, only one that I remember being high ESR was the 400v 1uf one in the power supply, though those are known to fail over time as far as I've seen and cause startup issues.
The SVHS sub-board used in this and other decks also seem to have some SMD caps that can fail over time, and cause bad or missing output for SVHS playback, though that seems to not be an issue so far (it's one of these hybrid IC boards that are annoying to fix.)
Which of the servo board capacitors go bad? I suppose it's not impossible that that could cause other issues too like the reset issue which is presumably some issue on the servo board.
