Well, you are putting a CRT in a TV that it was not exactly made for, so there will be some changes to be made, I'm not sure if I am looking at the right schematic, pilot_tv37_sams_62-16, but if it's right, you say that “the pot is maxed to open” (R4) vertical size, if this is the case, then all you need do perhaps is raise the value of R58 to 1.1 or 1.2 meg or so, just see how it goes, or, if by chance, you have the pot at the other extreme, then lower it to 900-800k.
