I recently picked up a DK Jr It fired up and plays you can here it coin up and play. But the screen was all messed up vert lines of Color from the game but you couldn't make anything out. I adjusted everything. and when I got to te horizontal hold adjustment it fixed it and it looked perfect I played it for a half an hour, very proud that I fixed it. I turned it off and came back out later to show my wife I fixed it and it was right back to the vert lines. What could cause this?
