Going to preface this by saying I'm used to the MS9 in my NAC, which has horizontal width control on the remote board. I'm not very familiar with using the coil. In my MVS-U4 the horizontal width is slightly too wide, it's not unplayable but kind of annoying. I have a long fiberglass adjustment tool with a flat screwdriver head, and the coil has an indentation in it that looks like it's meant to be tuned with something like this, unlike most width coils I've seen pictures of which look like they need a hex style tool.

The coil seems to be stuck in place and won't move, I haven't applied a ton of force from fear of breaking it but it feels like it's not really supposed to be adjusted the way I'm trying. Is there a trick to these that I'm missing?

I have a similar issue with horizontal collapse on my MS826. I believe they take hex for adjustment.

I tried adjusting it live and it heated up my hex and burnt my hand.

I'm gonna adjust it off from now on, but I think the coil itself needs to be replaced.

I'm wondering where you can purchase the coil from if that ends being your issue as well.

Mine does not take hex for adjustment, it has nowhere that looks like a hex bit should go, only a flat indent. I do know from researching this that you should never use a metal tool in a coil because of your exact issue, instead get an alignment tool set. It will heat up something conductive even if it's working normally.

Got it working, there was some loctite like substance on both coils that could only be seen from behind. Didn't really have to do anything, just let it warm up for a couple hours and they moved freely. The range of adjustment was not huge (almost imperceptible if you're watching the screen while adjusting) but moving both fully clockwise did just enough to not cut off the tips of health bars in fighting games or the borders in something like Money Idol Exchanger.
