Sanyo 20EZ - can't adjust B+ - stuck at 80v - pot? flyback?

I have a Sanyo 20EZ that I got from a warehouse raid and I just put it in the Radarscope I got running with the help of Spaeth (thanks!). It was working pretty great for most of the first day but then it started getting brighter and brighter throughout the day. I kept adjusting it down but it kept going bright again. It eventually got to a point where I couldn't adjust it all and make it look good. No matter how much pot tweaking I did, it looked like ass.

So, I decided to test the B+. It was at around 80v. If I move the pot it doesn't change at all. It's pretty much glued at around 80v.

So, is this a pot or should I be looking to get a new flyback? OR is it something else? Any ideas? Monitor has original caps but the picture was pretty damn good when it was working nicely.
 
Just an update on this topic...

I replaced the flyback and it didn't fix my B+ issue. But I think it fixed my brightness issue. So, I replace the B+ pot and that fixed the B+ issue. so, yeah...
