25" K7000 on the bench. Was a "parts" chassis that I revived. After getting it all fixed up, it's working and looking great but when testing the V.Size adjustment, I noticed that if I went all the way down with it, I get these black blobs. Suspected the flyback so I replaced it. Nope. The whole chassis was capped, reflowed, and all the stuff I normally do. Just curious if anyone has seen this previously before I spend hours trying to solve it. Thanks.
