I have multiple DKjr boards all seem to have broken/problems with the 50K horz position pot. I replace both the H and V 50k pots on the board and still eveytime I try and adjust the H position pot the video scrambles and no amount of adjustment will correct it. If the board sets for several minutes it will usually be ok and the video is fine until you try and adjust the H pot. What am I missing? What else controls the H position on these boards. The monitor is fine it works with other DK/DKjr/DK3 boards without issue.
