Yoke wires are tight.
It was after the cap kit that the problem began. I plugged it in and after about 2 seconds I saw smoke rising from the area in back between the flyback and the tube. I turned it off, removed the chassis, and checked for solder bridges. I found possible issues and put it back to get only the horizontal line.
I will remove the chassis, check for cold solder joints and test the Xistors.
